The quake struck at 6:47 pm local time Monday (1247 GMT) on the Pacific Ocean's coast of Oaxaca near the coastal municipality of Puerto Escondido and was felt 282 miles (455 kms) away in Mexico City, where buildings swayed slightly.

Its epicenter lay at a depth of 21 miles (35 kms) at Miahuatlan, Oaxaca, 34 miles(55 kms) north of the fishing and resort town of Puerto Angel, said the U.S. Geological Survey's Earthquake Information Center.

The National Seismological Service said the quake was felt in nearby states of Morelos and Puebla.

In Mexico City, the temblor caused some buildings to be evacuated as a precaution, said an official.
