As it happened: Japan earthquake on Wednesday

  • Japan's Emperor Akihito has said he is "deeply worried" about the crisis his country is facing following last Friday's earthquake and tsunami
  • Technicians temporarily abandoned the quake-crippled Fukushima Daiichi nuclear plant because of a spike in radiation levels
  • The number of confirmed dead and missing now stands at nearly 13,000
  • About 450,000 people have been staying in temporary shelters. Snow has been reported in affected areas - with more freezing weather forecast
  • Live page reporters: Stephanie Holmes, Aidan Lewis, Matthew Davis, Daniel Nasaw, Yaroslav Lukov, Anna Jones, Olivia Lang and David Gritten
  • All times in GMT

2359That concludes our live coverage for Wednesday. Join us shortly for our reporting on Thursday's events.

2253 Channel 4's Jon Snow tweets: "Have reached Tokyo Nareta airport in 15 mins less than usual no rush hour sadly. Strong head winds blowing to sea sunny. Radiation?"

2348It should be noted that the Tokyo Electric Power Company has a poor record on revealing the extent of problems at its nuclear facilities. In 2002, senior executives were forced to resign after the government disclosed that they had covered up a large series of cracks and other damage to reactors. In 2006, the firm admitted it had been falsifying data about coolant materials in its plants.

2340Jeffrey in Kawanehon, Japan writes: "It's amazing how foreign governments are inflaming fears in order to score political brownie points. It's also amazing how many fair-weather friends Japan has in the current expat community. Japan has been good to me and I'm staying to help."

2336Kuni Yogo, a former nuclear power planner at Japan's Science and Technology Agency tells the New York Times that the Japanese government and the Tokyo Electric Power Company, the operator of the troubled nuclear plant, "try to disclose only what they think is necessary, while the media, which has an anti-nuclear tendency, acts hysterically, which leads the government and Tepco to not offer more information".

2332The Guardian reports that Greg Jaczko, the chairman of the US Nuclear Regulatory Commission, was pressed on his assertion in Congress earlier that there was no water remaining in reactor 4's spent fuel storage pool, which was subsequently denied by Japanese officials. He told reporters: "The information I have is coming from staff people in Tokyo who are interfacing with their Japanese counterparts. I've confirmed that their information is reliable." Mr Jaczko nevertheless added: "It is my great hope that the information is not accurate."

2323John in Nerimaku, Tokyo writes: "We go to bed not knowing what the morning will bring. We wake up hoping that nothing more serious is happening at the nuclear plant. This stress is beginning to affect everyone - my children too."


2319The level of radiation detected at the Fukushima Daiichi plant has fallen steadily over the past 12 hours, an official at Japan's Nuclear and Industrial Safety Agency has said, according to the Reuters news agency. A level of 752 microsieverts per hour was recorded at the plant's main gate at 1700 on Wednesday (0800 GMT), said Tetsuo Ohmura. The monitoring point was then changed to the plant's west gate and readings were taken every 30 minutes, he said. At 0500 on Thursday (2000 GMT on Wednesday), the reading was 338 microsieverts per hour. That level is still much higher than it should be, but is not dangerous, Mr Ohmura added.

2311 Steve Nagata tweets: "Woke up feeling cold. Just saw a shot on tv of firefighters in the quake area walking with heavy snow. I think I can take the chill in Tokyo."

2308Harry in Nagoya, Japan writes: "There is fear spreading among the Japanese and foreigners, as day by day the supermarkets empty. I am angry at the lack of proper information. The local media and people persist in their idea that there is no need for panic while the western media and foreign embassies insist that their citizens should go back to their respective countries."


2303An additional 28,000 people have been evacuated from areas near the stricken Fukushima Daiichi plant to avoid possible exposure to radiation, NHK television reports. But many temporary shelters in the 31 municipalities in Fukushima prefecture were too overcrowded to cope with the influx and had to turn them away. The displaced are now heading to neighbouring prefectures.

2259Martin in Tokyo writes: "There does seem to be a lot of panic, but it's not here in Tokyo. There is tension and obviuosly worry. However people are going about their business as normal."

2255 The IAEA has released information about the temperature of the water in the spent fuel storage pools inside reactors 4, 5 and 6 at Fukushima Daiichi. Spent fuel that has been removed from a nuclear reactor generates intense heat and the water is usually kept below 25C. The IAEA says that the temperature of the pool at reactor 4 was 84C on Tuesday morning. On Wednesday morning, it was 62.7C at reactor 5 and 60C at reactor 6. Current reports say the pools at both reactors 3 and 4 are boiling. Reactor 4's pool may even be dry.


2253A spokesman from the British government confirmed that a Cobra emergency response committee meeting was held on Wednesday evening to discuss the situation in Japan. It was described as an opportunity for departments and the goverment's science adviser to update the meeting on the latest situation.

2244 Mark MacKinnon of the Globe and Mail tweets: "More alarming warnings from embassies in Tokyo suggesting citizens leave. Not bc of radiation, but bc supplies of food, fuel running low."



2242The director general of the International Atomic Energy Agency (IAEA), Yukiya Amano, has said he will be travelling to Japan as soon as possible to get the latest information on the situation.



2239Ginette Sainfort, who was rescued six days after Haiti's earthquake in January 2010, sent a message of support to Japan. "God is great. We Haitians dealt with all the difficulties, all the problems with courage. They too (the Japanese) have to realise that these problems cannot handicap their lives. Today I feel sad to see once more the effects of this sinister thing. I know that the Japanese people are suffering enormously and I am ready to say to tell them have courage, courage."

2231John Luke from Nerimaku, Tokyo writes: "Remember, many people are wearing masks now because it's 'hay-fever season' NOT because they are worried about radiation. Your report gives the impression people are wearing masks because of fear. Please correct this."

2226Nick Bikkal from Tokyo writes: "I live within Tokyo city limits. I keep reading of radiation coming into the city from the plant 200 km north of us. Technically NE of the city. Embassies are urging their citizens to leave the city and country. How can radioactivity head our way when for the last few days all the weather reports have said the wind keeps blowing from the west or NW? The official weather reports back up my statement. Either I'm still underinformed or am being misinformed. Family and friends abroad are in a panic over me and my family but I say there is an attempt to confuse and create panic. It's a media tactic to keep people glued to them. I see little support given to those working hard to help, clean up & rescue. Instead of running away people should give what they can to those in need."



2218The BBC Damian Grammaticas in Sendai reports that a bowling alley is being used as a mortuary, as people continue to search for their loved ones. One man came looking for his wife, who disappeared in the tsunami. He could not find her name on the list of the dead, or the survivors.



2214Japanese auto companies have extended shutdowns of car-assembly plants affected by the earthquake and tsunami, reports the Associated Press. However, some parts factories in Japan plan to resume production later this week.




2201There is some anxiety at US military bases in Japan about exposure to radiation, Reuters reports. On a Facebook page for US Naval Forces Japan, some Americans voiced concern. One living in Atsugi, Japan, where radiation was detected at a naval base, asked about a potential evacuation. "Having a toddler and being pregnant, I need to know if they can get us going," wrote 21-year-old Chelsea Origer.




2156The yen has continued to surge in early Asian trade, hitting 76.52 against the dollar, reports AFP news agency.



2153Dominic Jones, who's originally from Cornwall, lectures at a university in Sendai. He told the BBC his family are packing their bags: "Amazingly, outside our apartment they're building a new house and the builders came back and started building yesterday, which I thought was a bit crazy. And the Post Office have come round and delivered some parcels. So there is some kind of normality. But I think especially the foreign nationals are very worried about the nuclear situation. And as we have two young children, we've decided that it's best for the children to move back to England temporarily."



2148Many airlines have suspended flights to Japan while at Tokyo's Haneda airport there are large crowds trying to get out of the capital. One man at the airport told BBC World Service: "My children are small and have their life ahead of them and I don't want them to be contaminated by the nuclear fallout."



2144Germany has advised citizens in Japan to consider leaving Tokyo joining a growing number of governments and businesses telling their people it may be safer elsewhere.



2142The Governor of the Fukushima region has criticised the official handling of the evacuation. Yuhei Sato said the people of Fukushima had reached the limits of "fear and anxiety". He said that if an evacuation was necessary, it would be difficult. "How do we move people, transport people?" he said. He said they had secured the "minimum food" but that daily supplies are all in shortage.

2130 The BBC's Tim Wilcox tweets: "Just come off air - latest tremor shaking buildings around us - like sinister fairground ride - nothing compared to what last fri #japan"



2118This disaster must not be seen as proof that fossil fuels are a "safe" alternative to nuclear power, writes George Monbiot in the Guardian. "While nuclear causes calamities when it goes wrong, coal causes calamities when it goes right, and coal goes right a lot more often than nuclear goes wrong.




2116The head of the US Nuclear Regulatory Commision, Gregory Jaczko, has told lawmakers that he strongly believes the US could "mitigate" the impact of a nuclear crisis similar to the one unfolding in Japan, Reuters reports.

2110Stuart Blackburn from Osaka writes: "Today, I and other Britons were contacted by the foreign office, and asked to refer to a report from the government's Chief Science Officer for advice. His conclusion was plain; even if the reactors meltdown, we would be in no danger. There is no reason to leave. For me, this was the clear, expert opinion I had been waiting for. I shall not leave Japan. I began to spread the word to friends. Until, that is, I read an article from the New York Times. The reactor blasts have exposed storage pools of spent fuel to the outside. With the cooling systems down, the water covering the fuel is boiling away, and engineers are unable to conduct repairs. Should the water evaporate away, the spent rods could ignite, sending huge volumes of radioisotopes into the air. 100 rapid deaths within 500 miles. Over 100,000 deaths over time. Of course, this is a worse-case scenario. But the once quenched debate is re-ignited. Should we stay? For now, we can only wait, and talk."




2057Andreas Persbo, director of the London-based Verification Research, Training and Information Centre, has told Bloomberg that although Japan is legally obliged to provide information to the IAEA and its member states, officials in Tokyo simply may not be able to do so. "In a crisis situation, the only ones that really know what is going on are at the site and they don't have time to pick up the telephone," he explained.


2046Japan's foreign ministry has asked foreign diplomats and government officials to remain calm and "accurately convey information provided by Japanese authorities concerning the plant", according to NHK television.


2038Experts warn that if radiation levels become too high, workers at the plant would not only be prevented from approaching reactor 4's spent fuel pond, but also the adjacent reactors, which also have malfunctioning cooling systems.


2035US officials have concluded that the Japanese warnings have been insufficient, and that, deliberately or not, they have understated the potential threat of what is taking place inside the nuclear facility, according to the New York Times. Gregory Jaczko, the chairman of the US Nuclear Regulatory Commission, earlier said he believed that all the water in the spent fuel pool at reactor 4 had boiled dry, leaving fuel rods stored there exposed. "We believe that radiation levels are extremely high, which could possibly impact the ability to take corrective measures," he told a Congressional committee.

2031Yumi from London writes: "It appears the Japanese press have not been reporting all the information that has been made available to the rest of the world. Having contacted family in Tokyo, Ibaragi and Tochigi; asking them to come and stay in London - they told us that Japan was completely safe, that radiation levels were lower than those produced by an X-ray. It appears the vast majority of people in Tokyo are oblivious to the "mass exodus" and say the running of public transport and open businesses are proof that everything is normal. My only hope is that the Japanese government become a little more candid so that those with an option to leave Japan can do so soon."


2027Japan's Nuclear and Industrial Safety Agency has said it is also concerned about the spent fuel storage pool inside the building housing reactor 3 at Fukushima Daiichi. The pools at both reactors 3 and 4 are reportedly boiling - there may not even be any water left in reactor 4's pool - and unless the spent fuel rods are cooled down, they could emit large quantities radiation. Radioactive steam was earlier said to be coming from reactor 3's pool. If cooling operations did not proceed well, the situation would "reach a critical stage in a couple of days", an agency official told the Kyodo news agency.


2019The US military will also fly one of its Global Hawk unmanned high-altitude reconnaissance aircraft over the site, possibly later on Thursday, to take photographs of the inside the building which houses reactor 4, Japanese government sources have told the Kyodo news agency. Global Hawks are already being used to survey the devastation caused by the earthquake and tsunami.


2014A special police van equipped with a water cannon - normally used to disperse rioters - meanwhile arrived at the power station early on Thursday. Tepco plans to use the cannon to spray water onto reactor 4's spent fuel storage pond. The cannon is thought to be strong enough to allow engineers to remain a safe distance from the complex and limit their exposure to radiation.


2010More on the power line being laid to the Fukushima Daiichi plant to help restore the reactor cooling systems: Tokyo Electric Power Company (Tepco) spokesman Naoki Tsunoda has said it is almost complete, and that engineers plan to test it "as soon as possible", according to the Associated Press. Reviving the electric-powered pumps might allow the engineers to finaly cool the overheated reactors and spent fuel storage ponds.

2002Dominic Jones from Sendai writes: "We are one of the lucky families with no cooking gas but shelter, heat, electricity, water and some food. We are not complaining, our hearts go out to our friends in temporary shelters in conditions much worse than ours. As my wife Eri and our two young children Lawrence, aged 7, and Michelle, aged 2, are asleep, The Clash's famous rock anthem of 'Should I stay or should I go?' plays in my head. We are emotionally worn out and torn between the urge to return to England to loved ones or stay with loved ones in Sendai. The main questions with no answers are: Will there be safe food and water in the coming days, weeks, months? Will the Fukushima nuclear situation improve? Will another earthquake come and knock out our "life line" as the Japanese call the combined utilities of water, power and communication. Now that the Foreign Office has advised Britons to leave northern Japan, I am making preparations to leave."


1956Earlier, the National Police Agency said it had confirmed 4,314 deaths in 12 prefectures, while 8,606 people remained unaccounted for in six prefectures. The Kyodo news agency reports that, in an unprecedented move, police in the badly affected provinces of Iwate, Miyagi and Fukushima have begun announcing the names, ages and addresses of people whose bodies have been recovered and identified based on their belongings alone, and not through a post-mortem examination.


1945Some 80,000 Japanese military personnel, police officers and firefighters have been deployed to areas affected by the earthquake and tsunami, the Kyodo news agency reports. The government has also mobilised 10,000 military reservists for the first time since Japan's Self-Defence Forces were established in 1954. About 420,000 displaced people are staying in more than 2,200 emergency shelters in eight prefectures.


1933Yukiya Amano, the director general of the International Atomic Energy Agency (IAEA), has said he plans to fly to Japan on Thursday to get further information about the situation at the Fukushima Daiichi nuclear plant. The BBC's Kerry Skyring says Mr Amano is under pressure to demonstrate his agency is informed and able to communicate a clear picture of what is happening. "At daily press briefings he has been unable to explain why the information provided is so sketchy. As well as flying to Japan to what he says are high level meetings he is creating two teams who will also go there, one with expertise in nuclear safety, the other in radiation protection," our correspondent adds. Asked if the situation at Fukushima was now out of control, Mr Amano said: "It is very serious. The government and operators are doing everything they can. I hope their efforts will be successful."


1924US Treasury Secretary Timothy Geithner has said it is too early to say what effect the disasters in Japan could have on the US economy. "It's a hard judgement to make at this stage," he told a Congressional committee. "Our focus now is, as it should be, on trying to do as much as we can to help them mitigate the humanitarian costs of the catastrophe there, and we'll offer them every assistance we can."


1917BBC business reporter Mark Gregory says: "You would expect the currency of a country in crisis to fall in value. But the opposite has happened in Japan. During trading on Wednesday, a dollar was briefly worth less than 80 yen for the first time in 16 years. It is driven by the belief that Japanese firms will need to repatriate some of their vast overseas holdings to pay for reconstruction. This would mean swapping other currencies for yen, pushing the yen higher. This is bad news, though, for Japanese exporters. A high yen means their goods become less competitive in foreign markets just as they are reeling from the impact of an earthquake, a tsunami and a nuclear emergency. A similar rise in the yen took place after the Kobe earthquake in 1995. Indeed, that was the last time the Japanese currency was valued near the current level."


1913The yen has hit a 16-year high versus the dollar on the currency markets, and is within a few cents of its highest level since World War II. A high currency value could make it harder for Japanese firms to compete in trade at a time when they are already having to cope with multiple emergencies.

1906Jun Suzuki in Kashiwa-shi, Chiba, Japan writes: "Most of the people here are confused. Some Japanese people in the Tokyo area have also started to evacuate to the west. We really appreciate the rescue teams from other countries and rescue dogs from England. They are involved in a lot of activity for us right now. Really much appreciated.

1900 Mr Jackzo said the high radiation levels would make it very difficult for workers to get near the reactor. "The doses they could experience would potentially be lethal doses in a very short period of time," he said, but added that the NRC's information on the situation was "very limited".


1859 More from NRC chair Gregory Jaczko. He told Congress: "We believe that secondary containment has been destroyed and there is no water in the spent fuel pool and we believe that radiation levels are extremely high which could possibly impact the ability to take corrective measures."


1854 He told the BBC: "We are informed by the science, and the science says that outside the 30km exclusion zone there should not be a threat to human health. If we thought there was a threat to human health of a severe level in Tokyo we would have much stronger advice at this stage, saying that people should leave with immediate effect. What we are saying is that people should consider leaving Tokyo and northern Japan."


1853 Mr Browne said trains and planes were available at the moment for people wishing to leave, but that "if the capacity needs to be increased by the British government we will do that".


1851 UK Foreign Office minister Jeremy Browne has said the advice to British nationals is "not an order" but that given the situation "British nationals should consider leaving Tokyo and northern Japan and that the capacity exists for them to do so".


1843 White House spokesman Jay Carney has said the latest US evacuation order does not signal a lack of confidence in the Japanese authorities, AP reports. He said US officials were basing their recommendations on what they would do if such an incident happened at home, and that they had consulted with the Japanese government before issuing the advice.

1841 Ross in Osaka, Japan writes: "The lack of details available - or what seemed misleading at the time - encouraged me to leave the Hitachi area on Monday with my wife and young child by car. Now we are staying with friends in the Osaka area and have access to internet etc. Despite this access to the media, I still feel in the dark. There are so many opinions and suggestions, different governments giving varying advice - nobody knows what is going to happen."

1837 Gregory Jaczko, head of the US Nuclear Regulatory Commission (NRC) has said there is no water left in the spent fuel pool in reactor four, adding: "We believe that radiation levels are extremely high." Mr Jaczko was speaking to Congress in Washington and it was not immediately clear where his information had come from.


1832 The AP news agency is quoting Tepco as saying a new power line is almost ready which could end the crisis. The disruption of power to the pumps which send coolant through the reactors is what led to their overheating.


1825 Reuters reports that the quake has led to the shutdown of roughly one third of Japan's oil refining capacity of 4.5 million barrels per day. More than one fifth of its nuclear capacity, estimated at 49 gigawatts, is also believed to have been cut off.


1823 Our correspondent says there is also growing suspicion that the government and the Tokyo Electric Company (Tepco) are not telling the whole truth about the danger to the public. "We don't trust them," one young mother told him. "They want people to stay calm so they cover up the truth. We are all very afraid she said and we want to find a way to leave the country."


1821 The BBC's Rupert Wingfield-Hayes in Tokyo says there were hundreds of people in the main train station on Wednesday afternoon trying to board bullet trains heading south to Osaka and beyond. "Many were families with young children. They said they wanted to get far away from Tokyo and the radiation danger," he says.


1818 The US Environmental Protection Agency says it is increasing its monitoring of radiation along the western coast and Pacific territories, AP reports. However the US Nuclear Regulatory Commission has said it does not expect harmful levels to reach North America.


1810 The legal exposure limit for the workers was raised on Wednesday from 100 to 250 millisieverts, a move officials said was "unavoidable". Most individuals will absorb 6 millisieverts a year, AP reports.


1809 "I don't know any other way to say it, but this is like suicide fighters in a war." That's how Keiichi Nakagawa, associate professor of the Department of Radiology at the University of Tokyo Hospital, described the 180 workers battling flames at Fukushima.


1806 The British embassy reports that there is still "no real human health issue that people should be concerned about". But the statement continues: "Due to the evolving situation at the Fukushima nuclear facility and potential disruptions to the supply of goods, transport, communications, power and other infrastructure, British nationals in Tokyo and to the north of Tokyo should consider leaving the area."


1803 The UK is advising its citizens to consider leaving northern Japan, Reuters reports.


1759 The embassy says there are "numerous factors in the aftermath of the earthquake and Tsunami, including weather, wind direction and speed, and the nature of the reactor problem that affect the risk of radioactive contamination within this 50 mile (80 km) radius or the possibility of lower-level radioactive materials reaching greater distances."


1757 This is an extract is from the US embassy's advice to its citizens in Japan: "Consistent with the NRC [Nuclear Regulatory Commission] guidelines that apply to such a situation in the United States, we are recommending, as a precaution, that American citizens who live within 50 miles (80 kilometers) of the Fukushima Nuclear Power Plant evacuate the area or to take shelter indoors if safe evacuation is not practical."


1755 Earlier on Wednesday, UK Foreign Secretary William Hague said the team had been sent home because they were not integrated into the wider rescue effort and had not brought their own logistical supplies.


1752 Mr Gray said the fault lay with the embassy. "The Japanese government issued a permit but we needed a letter from the British embassy to get the permit. They said because we weren't part of the British response, we're a non-government organisation, we couldn't have a letter."


1750 The International Rescue Corps has returned to the UK after it was sent back from Japan. Team leader Ray Gray said he was disappointed to be home so soon. "We flew over there with the intention of doing what I thought would have been a good job and a worthwhile job at the request of the Japanese government, and we've spent two days in an airport because we couldn't get a permit to get on the road from the British embassy."


1743 The Swiss foreign ministry said it would lay on charter flights if necessary to bring Swiss nationals home.


1742 Switzerland has also advised that its citizens leave north-east Japan and Tokyo. "At the moment, the development in the damaged nuclear facility is unpredictable and aftershocks are possible," said Swiss president Micheline Calmy-Rey.


1738 The US is advising its citizens living within 80km (50 miles) of Fukushima to evacuate or stay indoors.


1735 The Fukushima plant has a total of six nuclear reactors - all of which have been affected to varying degrees. Our annotated aerial picture shows the layout of the site and outlines what workers are facing at each reactor.


1729 US Secretary of State Hillary Clinton has said the US has to answer questions about "the costs and the risks" of nuclear power. "We get 20% of our energy right now in the United States from nuclear power," she said.


1726 Is Tepco becoming Japan's BP? BBC Business reporter Mark Gregory says that like BP's struggle with the Gulf of Mexico oil spill, the Fukushima operator has found itself struggling to cope with a situation it never saw coming.


1720 Kyodo reports that the US military is to fly an unmanned plane over Fukushima, equipped with infrared sensors, to give an aerial view of what is going on.


1711 The BBC's Environment correspondent Richard Black says the fact that the focus is now on reactor four - which was not operating at the time of the quake - is a surprise. He has been looking at what might have happened in the reactor and what is being done to save it.


1706 A reminder that all our reports, analysis, graphics and explainers have been brought together in one place, on the BBC's Japan Earthquake special report page.


1702 Mr Ellmann tells the BBC World Service that the embassy is taking calls around the clock, "receiving more than 1000 calls a day". A 114-strong French rescue team "is now in Sendai helping the Japanes search and rescue teams", he adds.


1701 France is arranging for extra planes to take their nationals home from Japan on Thursday. Julian Ellmann, spokesman for the embassy in Tokyo, says the advice for French citizens in the capital is "to go the south of Japan, to Kyoto, for example, and for those who want to, come back to France".


1659 Another survivor, Yoichi Yamazaki, said it was so cold he was unable to sleep at night. "Nature, it seems, is in no mood to give the survivors of this disaster any respite," says our correspondent.


1657 Roy Wilshire, a member of the British team in Ofunato, said he had been struck by the response of local people. "We had a fire-fighter from the local fire service with us whose own home had been destroyed by the tsunami but he had been working every day since. When you see the people in the streets and you can see the devastation in their eyes, this is a major shock to them."


1654 The BBC's Rachel Harvey is in Ofunato, a port city devastated by the waves. "There is what looks like a house that is now sitting on its side - it has obviously been picked up by the tsunami, carried along and then just dumped. And everywhere you look there are cars that are on top of buildings or in the high levels of buildings, left there as the water surged through."


1651 IAEA chief Yukiya Amano told the press conference earlier on Wednesday it was "not the time to say things are out of control". He said the Fukushima operators were "doing the maximum to restore the safety of the reactor".


1649 On Tuesday, Mr Oettinger had said Japan was facing an "apocalypse".


1645 A spokeswoman for EU Energy Commissioner Guenther Oettinger has clarified his earlier remarks that "further catastrophic events" were expected. "He just wanted to share his concern and that he was really touched by all the images of people and the victims," said Marlene Holzner. "In this sense, he said that according to we have seen in the media, it seems that in the nuclear power plants at the moment we do not have technical control."


1640 The number of dead is expected to rise. The mayor of Ishinomaki said earlier than 10,000 people were thought to be missing in his town alone and a similar number was given in Minamisanriku.


1639 The figures show 8,606 people are missing and 2,282 have been injured.


1638 Latest official figures show 4,314 people are now known to have died in the disaster, AFP reports.


1635 The BBC's Mike Wooldridge says the snow now falling heavily on the quake-hit zone is complicating efforts to rescue any survivors, and to retrieve bodies.


1633 Dr Richard Wakeford of the University of Manchester in the UK says the real health risks come from the consequences of the quake and tsunami, not the radiation. "If this was a developing country, we'd have people going down in their hundreds and thousands with the likes of typhoid and cholera by now. The questions should be: Where is the sewage going? What is the state of the drinking water? If I were a public health official, that would be my principle concern," he told Reuters.


1630 The EU is urging member states to check food imports from Japan for radiation, AFP reports.


1629 Writing for NPR, David Ropeik, an instructor at Harvard University, says the fear of radiation could be worse than the radiation itself. "Nuclear radiation is dangerous. But so is worrying too much about lesser risks and not enough about bigger ones."

1625 Robin, from Kamakura, Japan, writes: "One big problem is there is no guide to how long the evacuation will last, or how long there will be radiation affecting health in the worst scenario, or if things carry on as present."



1624 Mr Amano said: "At units four, five and six, which were not operating at the time of the earthquake, increased temperatures were observed at the spent fuel ponds. As far as radiation levels are concerned, those rates in Tokyo and other cities have increased very slightly but levels are not dangerous to human health."


1617 Mr Amano said he hoped to return from Japan with "firsthand information" and to address the issue of improving the flow of information to the IAEA, AP reports.


1615 IAEA chief Yukiya Amano has said the situations is "very serious". He has urged Japan to give more information, as he prepares to fly to the country./


1613 AFP reports that the Japanese yen rose to its highest levels against the dollar since 1995 on Wednesday.


1610 Risk modeling firm Eqecat has put the insured losses in Japan at between $12bn and $25bn, one of the costliest natural disasters in history, reports Reuters.


1606 We have a new gallery of images from Japan, showing some of the damage to Fukushima and the terrible conditions in which survivors and rescue workers have found themselves.


1605 Our news story now focuses on the Fukushima prefecture governor's criticism of the way the crisis has been handled. "Anxiety and anger felt by people have reached boiling point," said Yuhei Sato.


1558 The IAEA's Secretary General Yukiya Amano says he plans to go to Japan as early as Thursday, AP reports.


1556 Kyodo is reporting new plumes of smoke coming from the building housing reactor three.


1555 Fukushima's operators, Tepco, have said they want the military to make another attempt at dumping water from a helicopter onto the damaged reactor on 17 March.


1549 However, no US military personnel have shown signs of radiation poisoning, officials say.


1548 The Pentagon said some US air crews in Japan have been given iodine tablets as a precautionary measure.


1545 The Pentagon has announced that US forces must stay 50 miles (80km) away from the Fukushima reactor unless they have specific authorisation, Reuters reports.


1542 Here is the full statement from Russia's Ministry of Foreign Affairs on its evacuation plans: "In connection with the situation that has developed in Japan, the decision has been taken to temporarily withdraw family members of staff at Russian establishments in Japan, including the embassy in Tokyo, general consulates, the trade mission and a number of others, from the country, provisionally on 18 March. At present, there will be no evacuation from Japan of staff at our diplomatic missions, as well as staff from other Russian state establishments."


1540 US Energy Secretary Steven Chu says the US is trying to send equipment to Japan to detect radiation levels in the ground. The department is also sending 39 personnel.


1535 French Environment Minister Nathalie Kosciusko-Morizet has said "the worse case scenario is possible, and even probable, around the Fukushima plant," Reuters reports.


1529 More from the IAEA. Its latest briefing says that officials are preparing to spray water onto reactor four and possibly three. "Some debris on the ground from the 14 March explosion at Unit 3 may need to be removed before the spraying can begin."


1525 The EU's energy chief Guenther Oettinger has said that in the coming hours "there could be further catastrophic events, which could pose a threat to the lives of people on the island". He told the European Parliament the Fukushima nuclear site was "effectively out of control". "The cooling systems did not work, and as a result we are somewhere between a disaster and a major disaster."


1520 The IAEA says the Japanese authorities "have reported concerns about the condition of the spent nuclear fuel pool at Fukushima Daiichi Unit 3 and Unit 4". The pools are where the still-radioactive fuel rods are kept after they have completed their useful life in the reactor.


1516 Mr Chu said there were conflicting reports coming from Japan. The US teams who have travelled there are not only assisting the Japanese, but also ensuring that the US can secure its own measurements of what is happening, he said.


1515 US Energy Secretary Steven Chu has described events at the Fukushima plant as "appearing to be more serious than Three Mile Island". How much worse was not clear, he said, adding that it was very hard to tell how bad things were on the ground.


1512 The group's energy chief, Mike Childs, said the UK can meet all its energy needs through renewable sources and slashing waste. "New nuclear stations will inevitably starve these programmes of vital funds," he said. "We must invest in a cleaner, safer future. Nuclear power is a gamble we don't need to take."


1510 UK-based green campaign group Friends of the Earth have said the UK must now re-assess its plans to build more nuclear reactors.


1507 The Associated Press reports that the nuclear scare is proving to be a sales bonanza for traders in iodine, face masks and radiation meters. This is particularly the case in Russia, where people have painful memories of the false securities given in the wake of the Chernobyl disaster. "It is a pity that certain businessmen are trying to profit on the situation," Olga Shekhovtseva, an Emergencies Ministry spokeswoman in Russia's Primorsky region, told AP.


1505 "They are a respected organisation and we want them to be able to help in many occasions in the future," Mr Hague said of IRC. "But I think sometimes it's convenient to blame our embassies for difficulties which have arisen in other ways."

But if they've got a live map that shows the changes in radiation, they'll see that Tokyo is right on the absolute edge and nothing is going to give any individual in Tokyo a problem", she said.

The nuclear plants are very scary. If the wind direction changes, the radioactivity might reach Fukushima city. I heard places 30 minutes away from me are contaminated and that we should not touch any rainfall. I do not want to be exposed to radiation in any way. But, I cannot go to another place because there is no gasoline and the trains are not running. I will do what I can do. I just hope that there are no more problems with the nuclear plants."



1431 The UK Government's Chief Scientific Officer, Prof John Beddington, has sought to allay fears of radiation exposure. He told a press conference at the UK embassy in Tokyo: "What I would really re-emphasise is that this is very problematic for the area and the immediate vicinity and one has to have concerns for the people working there. Beyond that 20 or 30 kilometres, it's really not an issue for health," he says. The full and very interesting transcript is available on the embassy's website.

1423 Russian President Dmitry Medvedev and Turkish Prime Minister Recep Tayyip Erdogan have vowed to press on with plans to co-build a £12.5bn ($20bn:14.3bn euro) nuclear power plant in Turkey. Mr Medvedev said the project was different from Japan in both age and the level of protection. "Even after what happened in Japan there will be no radical review of security measures as they are already sufficient," he said.

"I don't know how many of the phone numbers saved on your mobile phone you know by heart. How do you reach someone whose number you have in the mobile you lost ? These are the little details that make this much more complicated."


1418 Philippe Stoll from the International Committee of the Red Cross in Geneva says it is difficult to identify who has survived the earthquake and tsunami and who has been killed.

There is something remarkable about the Japanese ability to subside their worries and just get on with life."


1406 The BBC's Chris Hogg in Tokyo says the city is still relatively calm. The risk for the authorities is that fear and panic could cause more problems than the radiation itself, he says.

1318 Colin Ellis, of the British Private Equity and Venture Capital Association, has told the BBC that the long-term impact of the disaster in Japan on the international economy will be limited. "It's a net exporter rather than a net importer, so it doesn't suck in loads of demand from the rest of the world," he told the BBC World Service. "It will definitely impact in terms of Asian growth, but it may be partly about recalibrating away from the factories that are shut and the infastructure that has been destroyed to elsewhere in Asia."





1311The BBC's Clive Myrie, in a school that has been transformed into an evacuation centre in Yamagata, says people are being tested for radiation when they arrive.

And that takes a long time to build up, even in situations when there is no apparent risk. So it's a very tricky issue."

0722 Charles Chen in Tokyo writes: "There is a lot of uncertainty and anxiety for people in Tokyo - especially amongst foreigners - regarding the nuclear situation in Fukushima. But I believe that part of the anxiety is due to the reporting. Speaking as a scientist, it may be true that 'higher than normal' levels of radiation have been measured in the Tokyo area; however, that must be put into proper context in terms of what levels are potentially harmful to human health. We are not anywhere near the level of danger."



0719A helicopter used to pour water over one of the reactors has taken off, Japanese TV reports.



0714A reminder that freezing weather is forecast over the coming days in Japan, making things even tougher for those made homeless by the earthquake and tsunami. Temperatures have already plunged to 0C in many of the affected areas."

0556Peter McArthur, an English language teacher, tells the BBC that he and his wife have now moved from Narita, Chiba prefecture, to Osaka because of safety concerns. He says: "We decided to get out because the stress and worry posed a threat to my health. In fact, I've probably been exposed to more radiation on the flight than I would have been if I'd stayed put! My wife feels ashamed to leave behind family who are dutifully going to work as normal. I'm torn because I feel a commitment to Japan and their way of life, but the stress was starting to affect my health."

I want to see more rescue efforts there. You have to make lots of judgments in really quick time: where to go, what to do, when to leave - without having much information. That's really hard, the instinct. That's very critical. Quick, smart judgments when you have limited information. And limited time. And limited fuel."

0017 Masayuki Okumiya, from Tokyo, Japan, writes: "It is 0900 in Tokyo, and the scenery of commute looks normal. JR Chuo-Line is operating on schedule, and there are as many commuters in stations as ever without any panic nor confusion, seemingly. I have heard that some companies advised their employees to stay at home during this week, but don't know how many corporates are doing like that. I am worried about the situtations at the nuclear plants of course, but it doesn't look like imminent. Hopefully, my judgement, instinct, hunch, or whatever is right."


0010 Tokyo shares are 3.73 per cent higher due to bargain buying in the wake of a massive two-day sell off of stocks amid fears of the threat of nuclear meltdown.


0008The Japanese authorities are still struggling to cope with the humanitarian aftermath of Friday's earthquake and tsunami. More than 500,000 people are living in temporary shelters, which are short of water, food and fuel - while more freezing weather and snow is predicted for the days ahead. Nearly 3,500 people are now known to have died and many more remain unaccounted for. Ninety-one countries have offered aid ranging from blankets, to search dogs and military transport aircraft.


0003A new fire that broke out inside reactor 4 at the Fukushima Daaichi nuclear plant, which was damaged in Friday's earthquake and tsunami, appears to be out. This was the second time in two days that the reactor where spent nuclear rods were being kept caught fire. Workers at the plant are pumping sea-water through several of the plant's reactors in an effort to cool and stabilise them. Japanese media reports say radiation levels at the reactors remain too high for workers there to approach them. Japan's Prime Minister, Naoto Kan, and the International Atomic Energy Agency (IAEA) have expressed concern and called for the provision of more timely, and accurate information.
