BEIJING — A 5.6-magnitude earthquake scattered roof tiles and knocked over houses Saturday in northwest China’s Gansu province, state media said.

The earthquake struck at 5:49 a.m. in Longxi county at a relatively shallow depth of 10 kilometers (6 miles), the Chinese government earthquake center said. The epicenter was about 140 kilometers (87 miles) southeast of Lanzhou, the provincial capital.

Eight houses were destroyed and more than 100 were damaged, state broadcaster CCTV said. Videos posted online by state media showed emergency workers using shovels to clear bricks and other rubble.
