I have just spoken to a Red Cross relief worker who is in Lushan town, he says they urgently need more tents because thousands of people are unable to go back into houses and buildings.
There have been many aftershocks and the authorities are warning people not to go into their homes or businesses.
He told me many homes have collapsed, and even the strongest buildings are showing signs of damage.
We drove through the worst affected areas, and there was damage all along the roads. This earthquake has caused devastation and despair.
More than 100 have died and 5,700 have been injured in an earthquake in China. Many were trapped under buildings near Ya'an in Sichuan.
A powerful earthquake struck China's south western Sichuan province today, leaving 157 dead and more than 5,700 injured.
