At least 22 people were killed and hundreds others injured in a 5.8-magnitude earthquake that jolted Yingjiang County in southwest China's Yunnan Province around noon on Thursday. The county government updated the figures at 7:20 p.m., saying 201 people were injured, with 33 in serious condition. The earthquake toppled 583 houses or apartments, mainly in the county seat near the border with Myanmar, said Zhao Yunshan, director of Yingjiang government press office. Witnesses reportedly said people were buried under debris and part of a supermarket and a hotel caved in. The tremor triggered a power outage but telecommunication service remained normal in Yingjiang, according to Wei Gang, head of the county government. Li Shaobo, chief of Yingjiang Education Bureau, said two students died in the earthquake while another one suffered serious injuries. However, no school buildings collapsed, Li said. The earthquake, the largest of more than 1,200 minor tremors over the last two months in the region, is believed to have caused serious damage and loss, said Liu Jie, a director with the earthquake forecast department in the China Earthquake Networks Center. The epicenter, with a depth of 10 kilometers, was monitored at 24.7 degrees north latitude and 97.9 degrees east longitude, according to the China Earthquake Networks Center.
