BEIJING - Rescuers rushed to find victims buried by twin shallow earthquakes in north-western Gansu province which killed at least 89 people and injured more than 800 others, state media and local officials said.
The 5.9- and 5.6-magnitude tremors hit Min and Zhang counties in Dingxi city in Gansu early Monday morning. They set off landslides which buried often crudely constructed local houses, state broadcaster CCTV reported.
They were also felt in the provincial capital of Lanzhou, 177km north, and as far away as Xian, 400km to the east.
"More than 21,000 buildings were severely damaged and more than 1,200 have collapsed," said an official at the provincial earthquake bureau, adding that 371 aftershocks had been recorded.
Pictures from the scene showed simple buildings reduced to rubble, with pieces of corrugated metal scattered all over. In one location, 12 people were buried, a witness told CCTV. "The rescue work is tough, because the house has been completely buried," the man said.
President Xi Jinping called for all-out rescue efforts and put "saving lives" as the top priority. Nearly 3,000 firefighters, police officers, soldiers and local government workers had been sent to the area, the official Xinhua news agency said, adding that rescue efforts had been hampered by landslides and roads had been blocked by heavy rain in previous days.
"We are rushing to the scene," Dingxi's vice-mayor told CCTV, which showed an orange-suited rescue worker riding on a tractor.
A red rainstorm alert was issued for the area, which could further obstruct rescue attempts in the mountainous region.
