A moderate earthquake jolted southwestern China on Sunday, killing one person and injuring 11 others, officials said. More than 100 houses were damaged or destroyed. The quake struck at 5:37 a.m. in Sichuan province and registered a magnitude of 5.2, the U.S. Geological Survey said. It said the quake was centered at a depth of 11.6 miles (18.6 kilometers). The Sichuan provincial seismological bureau said all of the casualties occurred in the town of Moxi, near the epicenter, with a population of about 30,000 people. A 30-member team arrived in Moxi to assist the local government, the bureau was quoted as saying by The Associated Press. Sichuan province is still rebuilding from a magnitude-7.9 quake that struck in May 2008, leaving almost 90,000 people dead or missing.
