Strong earthquake strikes off the coast of Mexico, no immediate reports of damages inland

MEXICO CITY - A strong earthquake has struck off the coast of Mexico, but there were no immediate reports of damages inland.

The U.S. Geological Survey reports a preliminary reading of 6.9 magnitude. It says the temblor was centred 82 miles (133 kilometres) northeast of Guerrero Negro, and hit some 6.4 miles (10.3 kilometres) below the surface.

It follows a 6.4 magnitude quake which struck a sparsely populated area in the mountains of western Mexico on Wednesday, and caused tall buildings to sway more than 200 miles (322 kilometres) away in Mexico City.
