A woman was trapped in a house after a mudslide caused her to fall into a hole, according to state media.

The latest quake struck at 8:20 a.m. local time (0420 GMT) near the village of Yanzhou in the province of Jiangxi, where people are mostly concentrated.

The earthquake, which is centered about 2,600 kilometers (1,300 miles) west of Guangdong in southwest China, struck a reservoir located at 11 miles (20 kilometers) elevation, state media reported.

It was followed by mudslides in several villages, the People’s Daily reported.

“The ground shook violently, sending boulders flying and injuring a number of people,” the official Xinhua news agency said.

“More than 150 people were trapped in homes, while at least 18 were injured.”

“We don’t know what caused the tremors,” Xinhua said.

In the past, there have been several aftershocks in the region, the agency said, but the latest was the largest in years.

An earthquake hit the area on Wednesday, causing widespread damage.

The dam at Yanzhou reservoir was hit by mud and debris, according the local government, which said a mud-covered bridge over the Yangtze River was swept away.

The dam is part of the Yanzhou Reservoir, which provides drinking water to more than 10 million people, according state media outlet China Daily.

The reservoir was the focus of a series of aftershakes in 2017, but it has not seen an aftershock since.

More than two dozen aftersharks had been recorded in the area in 2017 and the Yangs are now under the control of the local county government, Xinhua reported.

The area around Yanzhou has been affected by the most recent aftershock in late September, the Xinhua report said.
