MEXICO CITY – A magnitude-5 earthquake shook southern Mexico on Saturday morning and was felt in some districts of the Mexican capital, but for the moment no injuries or material damage have been reported, the National Seismological Service, or SSN, said.

The temblor occurred at 8:22 a.m. local time (1322 GMT) in the southern part of Guerrero state on the Pacific coast.

The SSN said that the epicenter of the quake was located 31 kilometers (19 miles) southwest of Ciudad Altamirano in Guerrero, a town located at 300 kilometers (186 miles) southwest of Mexico City, at a depth of 55 kilometers (34 miles).

Guerrero civil protection authorities said that a preliminary check of the towns nearest the epicenter has already been carried out and at the moment no victims or material damage have been reported.

The temblor was felt in some areas on the Mexican capital’s west side, and in cities that included Morelia and the seaside tourist resort of Acapulco.

This was the fifth biggest earthquake in the month of August, since on Aug. 5 a magnitude-5.5 earthquake shook Sonora state and on Aug. 3 three hit Baja California and Sonora states ranging in strength from magnitude-5.8 to magnitude-6.9.

Mexico is in one of the world’s most active seismic zones, with the movement and interaction of the Pacific, Cocos, North American, Caribbean and Rivera tectonic plates.
