At least 28 hurt in Yunnan earthquake

"Daily necessities are in abundant supply at stable prices," the county government said.

On Sunday, rescue workers were combing through affected areas to remove safety hazards and demolish the most severely damaged houses.

"The main task is to eliminate danger. Evacuated residents will be allowed to return to transfer their property if rescue workers find no safety hazards in their damaged homes," Gao Yongjian, head of Tongguan, the worst-hit township, told China Central Television on Sunday.

Footage from the broadcaster showed cracks in many of the houses, which feature white outer walls and gray tile. Many tiles were broken and scattered on the ground, while some of the older houses had collapsed.

The Yunnan Seismological Bureau said 192 aftershocks had been recorded in Mojiang as of Sunday morning, with two registered at more than magnitude 4 and one at more than magnitude 3.

By Sunday, more than 1,800 workers were engaged in rescue operations, while the country's top emergency management authority initiated an emergency response and dispatched working teams to the scene, according to the Ministry of Emergency Management.
