The appeal by the Disasters Emergency Committee to raise money for people affected by Typhoon Haiyan has reached £13m in its first 24 hours.
Thousands of people died when the typhoon struck the Philippines on Friday.
The DEC, a coalition of 14 major aid charities that coordinates appeals in response to major humanitarian crises, launched its appeal yesterday and the first television appeals were broadcast last night.
A statement from the DEC today said the appeal had raised "a staggering" £13m in its first day.
Saleh Saeed, chief executive of the DEC, said the initial public response had been overwhelming.
"People have given so generously in such a short space of time," he said. "They have obviously been moved by the heart-breaking stories coming out of the Philippines of those struggling to survive."
The £13m does not include the government’s pledge to match donations pound for pound up to £5m.
The DEC said that the amount raised in the first 24 hours surpassed that given in the first day in response to the 2010 Haiti earthquake.
The Haiti appeal went on to raise £107m, the second highest total for any DEC appeal.The largest amount raised by a single DEC appeal is £392m, given to support people affected by the 2004 Asian tsunami.
