An official with the Tekes county, Ili Kazak Autonomous Prefecture in northern Xinjiang, confirmed that the quake caused no human casualties but leveled or damaged 2,120 homes.

The quake hit Tekes county at 6:06 p.m. on Friday (Beijing Time), with its epicenter at a mountainous region 60 kilometers from the county seat and 430 kilometers from Urumqi, capital of Xinjiang.

Rescuers have displaced 8,250 residents as their houses, most of which are mud-brick ones, either collapsed or became dangerous, said the official.

Some of the quake-affected residents were arranged to live in the houses of their relatives or their own tents. The local government has also sent 130 tents to them.

The quake also damaged four bridges in the county, including an 88-meter-long one on the Tekes River.
