M7.0 earthquake strikes off Mexico's Pacific coast, shakes resort city of Acapulco

ACAPULCO, Mexico – A powerful earthquake struck southwestern Mexico near the beach resort of Acapulco on Tuesday night, killing at least one man who was crushed by a falling post, and causing rock falls and damaging buildings, authorities said.

The 7.0 magnitude quake, which hit 17.7 kilometers northeast of Acapulco in Guerrero state, shook the hillsides around the city, downing trees and pitching large boulders onto roads.

State Gov. Hector Astudillo told local television that a man was killed by a falling post in Coyuca de Benitez, a small town just west of Acapulco. He and other authorities had earlier said there were no reports of major damage from the quake, which caused power outages in several states.

Mexican President Andres Manuel Lopez Obrador said the temblor had not caused major damages in Guerrero, the neighboring region of Oaxaca, Mexico City and elsewhere.

Acapulco is roughly 370 km from Mexico City.

In the central Roma Sur neighborhood of Mexico City, lights went off and scared residents rushed out, some wearing little more than pajamas, a witness said. Residents huddled together in the rain, holding young children and pets.

"It was terrible. It really reminds me of the 1985 quake every time something like this happens," said Yesmin Rizk, a 70-year-old Roma Sur resident.

A massive earthquake that struck the Mexican capital in 1985 killed thousands of people.

The U.S. Geological Survey (USGS) said the quake, initially measured at a magnitude of 7.4 and later downgraded to 7.0, was relatively shallow, only 19 km below the surface, which would have amplified the shaking effect.

Mexican state power utility the Comision Federal de Electricidad said in a statement 1.6 million users had been affected by the quake in Mexico City, the adjacent State of Mexico, and the states of Guerrero, Morelos and Oaxaca.
