Earthquake China: At least 80 people were killed Friday when a pair of earthquakes jolted a mountainous region of southwestern China, triggering landslides, damaging thousands of buildings and forcing thousands of residents from their homes.

The first quake, a magnitude 5.7, shook the border region of Yunnan and Guizhou provinces at 11:19 a.m. An hour later, the second quake struck, a magnitude 5.6.

The temblors destroyed or damaged 20,000 homes and injured more than 700 people in the largely impoverished, rural area. State media reported that 100,000 people had been evacuated.
