A 5.0-magnitude earthquake struck central China's Sichuan province near the border with Gansu province, the U.S. Geological Survey said Thursday.

The agency said the quake's epicenter was 70 miles northeast of the city of Mianyang, which was one of many places devastated by a 7.9-magnitude earthquake on May 12.

That temblor left nearly 90,000 people dead or missing.

There were no reports of casualties from Thursday's tremor, the official Xinhua News Agency said. It said the afternoon quake's epicenter was in Quhe township of Guangyuan city.

Cell phone service was down in Quhe, it said, but no casualties have been reported.

The earthquake was an aftershock from the May 12 quake, Xinhua said. Qingchuan county has registered nearly 1,600 aftershocks from Jan. 1 to March 8 this year, it said.

The quake could be felt in the provincial capital of Chengdu for about five seconds, the news agency reported.
