Nations from South Africa to Germany have been pledging aid to Algeria, where the death toll from Wednesday's earthquake is now believed to be more than 1,600.
Workers celebrated the rescue
The International Federation of Red Cross and Red Crescent Societies - which has a team of experts on the scene - is co-ordinating relief efforts.
The agency has already requested $1.5m to provide assistance including medicines, food and blankets.
Scores of bodies continue to be pulled from the rubble of Algeria's earthquake as rescuers race against time to find remaining survivors.
Among the reported successes was the rescue of an two-and-half-year-old girl, pulled alive from the remains of a collapsed building.
The discovery - reported by state radio - gave hope to those combing the rubble as international rescuers and aid workers stepped up their efforts, sending specially trained dogs and listening devices.
But a spokesman for the German Red Cross said time was running out.
"You can hear people scream under the rubble, but nobody can get to them," a spokesman, Luebbo Roewer, told the Associated Press news agency.
In addition to the 1,600 people thought to have died in Wednesday's quake, more than 7,000 have been injured.
The rescue of the baby in Boumerdes, near Algiers and the worst hit area of the country, took place 36 hours after the tremor hit.
Pulled out of the ruins of a five-storey building wearing just a torn orange T-shirt, the girl was given oxygen and taken away for treatment.
The girl's father told reporters rescue workers had initially thought they would have to amputate the girl's arm to pull her free.
Hundreds or even thousands may still be trapped under collapsed buildings.
Algeria has begun three days of national mourning, but there will be no pause in the rescue effort.
Medical and rescue teams have been despatched from across Europe, while South Africa sent recovery teams and relief and China's Red Cross donated $50,000.
The UN children's fund Unicef was set to send a plane carrying tents and emergency supplies for 120,000 people on Saturday.
A specially chartered flight left Stansted airport in Britain on Friday carrying representatives from the International Rescue Corps and other British charities who will help search for survivors.
Russian doctors and rescuers - including two with sniffer dogs - are on their way from Moscow, while Germany is providing 25 rescuers and the UK nearly 100.

Overnight, powerful after-shocks hitting Algiers and surrounding areas convinced many people to spend their second night in parks and open spaces.
But fear and grief is turning to anger at shoddy building standards of modern-day Algeria.
"The realtors are all crooks. If you see the buildings that date to the French colonial period, some of them are 150 years old - they didn't budge," a taxi driver told the AFP news agency.
In Reghaia, 35km (22 miles) east of Algiers, authorities requisitioned the municipal stadium, setting up tents for families whose houses were destroyed in the earthquake.
Food and water supplies are said to be running low and power and phone lines to the worst-hit areas remain cut.

I am originally form Thenia which is the epicentre and I have been trying since yesterday evening to call home but no luck, following the news on our Algerian TV which I found useless. I just hope every one is ok back home.

Waves from the earthquake have arrived in Ibiza and Menorca (we're due North), and have been so strong that they have damaged vessels in the harbours here.
Can't imagine what it must have been like in Algiers.
Send them what help you can.
It was the booming noise that first alerted us that something was wrong. However, before we had the chance to do anything the room was violently shaking. My wife took our baby and got under the dining room table. Two friends suggested we go outside. The first shock lasted two or three minutes and smashed plates in the kitchen and brought plaster and paint of the walls. There were some pretty big after shocks throughout the night. The state of many buildings is still uncertain with some having gaping cracks. We pray that there isn't another as lots of buildings in Algiers are unsafe and in disrepair. As I write we are still feeling the aftershocks.
I have never seen anything like it in my life and I'm not even sure if my family are still alive!
