Thousands stranded as storms hit China quake area

Continuous rain near the epicentre of China's May 12 earthquake has killed at least eight people and left 38 missing, with thousands stranded by mountain torrents, cave-ins and mudslides.

The downpours began to pound Mianyang city and surrounding countryside in Sichuan province, southwest China, on Monday night, Xinhua news agency said.

Mianyang encompasses Beichua and other areas that were the hardest-hit counties in the Sichuan earthquake, which killed at least 80,000 people.

In the latest disaster, at least 2,200 houses have collapsed and 6,500 people were stranded throughout the hilly region, Xinhua said. "Some pre-fabricated houses built after the quake and other residences were flooded," the report said.

More than 300 people were injured in the downpours, said an earlier report.

The rainstorms were separate to a typhoon which ploughed into a densely populated area of south China on Wednesday, triggering a "once-in-a-century storm tide" in several cities.

Earlier this month, a mudslide caused by the collapse of a mine waste reservoir killed more than 260 people in their village homes in northern China.
