The strong quake hit at 4:30 p.m. Sunday (Beijing Time) with a depth of 12 km and the epicenter in Longtoushan township, 23 km southwest of the county seat of Ludian, Zhaotong City.
As of 8:00 p.m., more than 120 residents were killed, over 180 were missing and 1,300 got injured in Ludian County, according to the local government.
It said more than 12,000 houses were toppled and 30,000 damaged. Transportation, electricity and telecommunications have been cut off in the county.
The quake has also led to at least 30 deaths in Qiaojia County of Zhaotong and nearby Huize County of Qujing City.
Ma Hao, a college student who is volunteering for the rescue at Longtoushan Township, told Xinhua that he saw bodies buried in ruins and helped to carry more than 40 injured people out of the collapsed buildings.
"Honestly, it's such a shame that we had no time to take care of the bodies. We need to help those alive first," he said.
"I felt a strong jolt on my fifth-floor home and some small objects in my home fell off the shelves," said a resident in the county seat of Ludian.
Most people rushed out of buildings to the streets. Electricity was cut, telecommunications services were affected and it was hard to reach people in Ludian by mobile phone, the resident said.
Another resident said it felt like "sailing a boat" when he was driving a car in the tremor.
Ma Liya, a resident in the county seat, told Xinhua via telephone that the streets were like "battlefield after bombardment". She added that the house of her neighbor, a new two-story building, was toppled.
