Earthquake shakes southern Mexico

A 5.4 magnitude earthquake shook Mexico's southern state of Oaxaca on Monday, Mexico's seismological institute said, shaking buildings as far away as Mexico City, but there were no immediate reports of any damage.

Luis Felipe Puente, head of emergency services, said via Twitter that authorities were monitoring states where the tremor was felt.

As usual, some offices were evacuated in Mexico City. Mayor Miguel Ángel Mancera ordered the activation of the emergency protocols for the metropolitan area and the firefighter department has reported no damage so far.

The U.S. Geological Survey said the tremor had a preliminary magnitude of 5.7 and its epicenter was in the southern state of Oaxaca, about six miles (10 kilometers) north of the town of Pinotepa de Don Luis. The quake struck at a depth of six miles (10 kilometers).

Felipe Reyna, coordinator for civil protection in Oaxaca, reported that there were no initial signs of significant damage or anyone being hurt.
