Another 593 people were injured and five were believed missing after the quake tore through Gansu Province, China Daily reported.
The quake hit along the border of two counties — Min and Zhang — at around 7:45 a.m. local time, according to state news agency Xinhua.
Emergency services are converging on the area, including the Red Cross Society of China, which is sending 200 tents and other supplies to shelter and sustain those left without homes.
Two men make their way along a damaged road in Hetuo township in Dingxi on July 22. The original quake and powerful aftershocks caused roofs to collapse, cut telecommunications lines and damaged a major highway linking Gansu Province’s capital of Lanzhou to the south, reports say.
