The confirmed death toll has now reached 14,000, but estimates suggest another 30,000 bodies remain undiscovered.

At one location, the naval base at Golcuk, there are 400 confirmed dead, but more than twice that number are missing.

BBC Ankara Correspondent Chris Morris says that pattern is repeated across the region, adding to the psychological strain on survivors who are unable to arrange funerals for their missing relatives.

They complain of anxiety, inability to sleep and the fear of being alone.

Concern as autumn approaches

Uncertainty is adding to the psychological trauma suffered by survivors

Special medical teams trained in dealing with trauma are busy across the disaster zone.

Turkish authorities have warned that the tens of thousands of homeless people will soon have to be moved from their makeshift tents into warmer shelters as autumn approaches.

"The weather is getting cold - how long can people live in tent cities? If you think of people's health, these tents have to be emptied," Health Ministry official Haluk Tokupcoglu told the Turkiye newspaper.

Aftershocks

Aftershocks are continuing nearly two weeks after the initial earthquake.

On Sunday, tremors measuring more than four on the Richter scale destroyed buildings that had been damaged by the earlier quake in the towns of Duzce and Bolu.

Residents were able to get outside in good time, and no injuries were reported.

International donors are assessing the damage

In Istanbul, a resident has filed a lawsuit against the local authorities and a building company after his house collapsed in the earthquake, killing his wife and injuring him and his daughter, Turkish TV reported on Sunday.

Nurettin Topuz has asked the Prosecutor's Office to open a criminal case, saying the builders and municipal authorities are responsible "in the first degree" for the death and injuries, the report said.

International community rallies round

Prime Minister Bulent Ecevit has said his government is hoping for a special loan from the United States to help with reconstruction.

A World Bank delegation is visiting the earthquake zone to assess Turkey's needs in the wake of the earthquake.

The European Union is aiming to collect up to 30 million euros ($31m) to assist Turkey.

Even Turkey's traditional adversary Greece is sending officials to Turkey to plan an aid package. This was announced by Greek Foreign Minister Georges Papandreou on Sunday.

The International Monetary Fund (IMF) is to send representatives to Turkey in September to assess the country's ability to stay solvent.

The IMF does not give emergency aid, but in urgent cases countries can apply to draw out up to 25% percent of their shares in the fund to help maintain their balance of payments.
