6.0 earthquake strikes off northwest Mexico - USGS
The quake was centred 57 miles (92 km) southwest of Los Mochis in Sinaloa, Mexico, at a depth of 6.3 miles, USGS estimates showed.
According to Mexico's national seismology institute, the quake measured 5.7 and was centred 99 kilometres (62 miles) southwest of Ahome, Sinaloa. It struck at 0526 GMT.
"We felt a tremor, the building shock and we went outside, that was all," said a local police officer in Los Mochis. "There is no damage to buildings and everything is normal." He knew of no injuries.
"We felt it hard, and it shook the building like we've never felt before," said Rafael Ines, an editor at Los Mochis paper El Debate. "It was a pretty hardcore shake."
