According to local authorities, more than 155,000 people have been affected and 48,000 have been relocated since a 6.6-magnitude quake jolted a mountainous area along the border of Hejing and Xinyuan counties in Xinjiang early Saturday morning. The quake was followed by several 3- to 4-magnitude aftershocks.

The earthquake destroyed 7,500 houses and severely damaged 21,000 others, the ministry said.

Local governments have allocated 8 million yuan ($1.26 million) for disaster-hit areas, and they have sent 2,400 tents, 2,500 quilts and other relief materials such as rice and edible oil to affected areas, the ministry said.

The quake-hit region, located about 3,500 meters above sea level, has been geologically active throughout history. Two earthquakes measuring higher than 7 on the Richter scale have jolted the region since 1900.
