Two moderate earthquakes shook China's northwest and southwest regions Tuesday morning, but there were no immediate reports of injuries or damage.
A magnitude-6.0 quake hit China's Xinjiang region about 60 miles (100 kilometers) from the city of Yining at 8:20 a.m., while the other temblor struck the area bordering Sichuan and Gansu provinces at 6 a.m. at a magnitude of 5.5, the U.S. Geological Survey said.
Several hours later, the official Xinhua News Agency said there had been no reports of injuries or damage.
The earthquake in Xinjiang occurred at a depth of 17 miles (27 kilometers), while the other temblor was 10 miles (16 kilometers) deep.
China's worst quake in recent years was a magnitude-7.9 temblor in Sichuan in May 2008 that left nearly 90,000 people dead.
