7.6 magnitude earthquake strikes near Acapulco, Mexico

A strong, long 7.6 earthquake with an epicenter in Guerrero state shook central southern Mexico on Tuesday, swaying buildings in Mexico City and sending frightened workers and residents into the streets.

The U.S. Geological Survey set the intensity at 7.6 at a depth of 11 miles underground. Mexico's National Seismological Survey said the temblor had an epicenter southwest of Ometepec. The quake was located 120 miles east of Acapulco.

Mexico City Mayor Marcelo Ebrard's Twitter account said the water system and other "strategic services" were not experiencing problems.

A person at Acapulco City Hall told NBC News that they felt the quake but had no immediate reports of injuries or damages.
