July 10 (Bloomberg) -- An earthquake in China’s southwestern Yunnan province toppled 10,000 homes and injured more than 300 people, state media said. One person was killed in the quake, Agence France-Presse reported, citing a provincial relief official.

The magnitude-6 quake struck at 7:19 p.m. local time yesterday in Guantun Township, about 200 kilometers (124 miles) from the provincial city of Kunming, Xinhua News Agency reported. Eight aftershocks rattled the region as relief officials distributed tents, medicines and food to people whose homes were destroyed, Xinhua said.

About 30,000 buildings were damaged across six counties in Chuxiong and 30 people were severely injured and being treated in the hospital, according to Xinhua. The U.S. Geological Survey put the magnitude of the quake at 5.7 with a depth of 10 kilometers.

Sichuan province in central China is still recovering from last year’s 7.9-magnitude quake that killed almost 70,000 people, flattened 4.5 million homes and left millions homeless. It was the country’s deadliest natural disaster in almost three decades.

About 3 percent of the 216,000 buildings that collapsed in the first two days after the Sichuan quake were schools, prompting parents to question whether shoddy construction added to the death toll. The government announced two months ago, shortly before the May 12 anniversary of the disaster, that 5,335 children were killed in the quake.

Officials in Yunnan plan to send 4,500 tents, 3,000 quilts and other relief items to the quake zone, Xinhua said. Teams from the Ministry of Civil Affairs, the National Commission for Disaster Reduction and the China Earthquake Administration are heading to the epicenter, according to the report.
