Strong quake jolts Mexico days after powerful temblor killed at least two

Mexico City — A powerful earthquake with a preliminary magnitude of 6.8 struck Mexico early Thursday, causing buildings to sway and leaving at least one person dead in the nation's capital. Residents huddled in streets as seismic alarms blared.

The temblor hit shortly after 1 a.m., just three days after a 7.6-magnitude quake shook western and central Mexico, killing two.

The U.S. Geological Survey said Thursday's quake, like Monday's, was centered in the western state of Michoacan near the Pacific coast. The epicenter was about 29 miles south-southwest of Aguililla, Michoacan, at a depth of about 15 miles.
