BEIJING — Rescuers dug through shattered homes Monday looking for survivors of a strong earthquake in southern China's Yunnan province as the death toll rose to at least 391 people with more than 1,800 injured.
About 12,000 mostly brick homes collapsed when the quake struck Sunday afternoon in impoverished Ludian county, about 370 kilometers (230 miles) northeast of Yunnan's capital, Kunming, China's official Xinhua News Agency reported.
The streets of the Ludian county seat of Zhaotong were like a "battlefield after a bombardment," resident Ma Liya told Xinhua.
She added that her neighbor's house, a new two-story building, had toppled, and said the quake was far worse than one that struck the area in 2012 and killed 81 people.
"I have never felt such strong tremors before. All I can see are ruins," Ma said. "The aftermath is much, much worse than what happened after the quake two years ago."
The magnitude-6.1 quake struck at 4:30 p.m. Sunday with a depth of 10 kilometers (6 miles), according to the US Geological Survey.
Its epicenter was in Ludian county township of Longtoushan. China's earthquake monitoring agency put the magnitude at 6.5.
State broadcaster CCTV said on its Weibo microblog account that at least 391 people were killed and 1,801 were injured. Another 29,400 had been evacuated, CCTV said. The death toll was expected to rise, once rescuers reached remote communities to assess casualties.
Many of the homes that collapsed in Ludian, which has a population of about 429,000, were old and made of brick, Xinhua said, adding that electricity and telecommunications were cut off in the county.
The mountainous region where the quake occurred is largely agricultural, with farming and mining the top industries, and is prone to earthquakes.
Relief efforts were underway, with more than 2,500 troops dispatched to the disaster region, Xinhua said. The Red Cross Society of China allocated quilts, jackets and tents for those made homeless by the quake, while Red Cross branches in Hong Kong, Macau and neighboring Sichuan province also sent relief supplies.
Premier Li Keqiang had reached the worst-hit area Monday afternoon to oversee quake relief, Xinhua said.
UN Secretary-General Ban Ki-moon offered "his condolences to the Chinese Government and the families of those killed," according to a statement from his office.
The statement said the UN is ready to "lend its assistance to efforts to respond to humanitarian needs" and "to mobilize any international support needed."
The White House also offered its condolences.
"Our thoughts and prayers are with the families of those that lost their lives," said National Security Council deputy spokeswoman Bernadette Meehan. "The United States stands ready to assist."
Chinese state broadcaster CCTV said the quake was the strongest to hit Yunnan in 14 years.
In 1970, a magnitude-7.7 earthquake in Yunnan killed at least 15,000 people, and a magnitude-7.1 quake in the province killed more than 1,400 in 1974. In September 2012, 81 people died and 821 were injured in a series of quakes in the Yunnan region.
In May 2008, a powerful quake in Sichuan province left nearly 90,000 people dead or missing. (AP)
