A 5.1 magnitude earthquake shook the northeastern Chinese city of Tangshan on Sunday, the government reported.
Rail service to Tangshan, 160 kilometers (100 miles) east of Beijing, was temporarily suspended while tracks were inspected for possible damage, the official Xinhua News Agency reported.
No deaths or injuries were registered, according to the Associated Press.
The quake struck at 6:38 a.m. at a depth of 10 kilometers (6 miles), the China Earthquake Networks Center reported. It said a second quake of magnitude 2.2 struck at 7:02 a.m.
An earthquake that struck Tangshan in 1976 killed at least 242,000 people in one of the deadliest natural disasters in history.
