Xinhua said about 12,000 homes had collapsed in Ludian, a county of some 439,000 people, north-east of Yunnan province's capital, Kunming.

All of the casualties reported so far are in Qiaojia County of the Zhaotong region, which appeared to be the hardest hit.

Ma Liya, a resident of Zhaotong, told Xinhua that the streets there were like "battlefield after bombardment", adding her neighbour's house, a new two-storey building, had collapsed.

The government is sending 2,000 tents, 3,000 folding beds, 3,000 quilts and 3,000 coats to the disaster zone, the report said.

After initial reports of a death toll of 26, the numbers of casualties rose sharply, passing 150 before Xinhua reported a figure of 367 killed.

The news agency says the epicentre of the earthquake was in Longtoushan in Yunnan's Ludian county.

Chen Guoyong, the head of Longtoushan township, told Xinhua that many houses had fallen and rescuers had been sent to the epicentre.

Many people rushed out of buildings onto the street after the quake hit, electricity supplies were cut and at least one school collapsed, Xinhua reports.
