A magnitude-7.2 earthquake struck southern Mexico’s Guerrero state Friday morning, the U.S. Geological Survey said.

The quake occurred on the Pacific Coast between the major resort towns of Acapulco and Zihuatanejo during Holy Week, when Mexicans traditionally flock to the beaches, and resorts typically run at full capacity.

The quake struck at 9:27 a.m. local time (10:27 a.m. ET) about 19 miles (31 kilometers) northwest of Tecpan, Mexico, according to the Mexican National Seismological Service, which measured its magnitude at 7.0.

The quake’s depth at the epicenter was a shallow 15 miles (24 kilometers), the USGS said.

At least one building was damaged in Mexico City, 165 miles (265 kilometers) northeast of where the quake was centered. But there were no reports of major damage, said Mexico City Mayor Miguel Angel Mancera.

Mexico City’s secretary of civil protection, Fausto Lugo, said electricity was lost in some parts of the capital and that some people reported being trapped inside elevators, but that there were no reports of injuries.

Tecpan is 54 miles (87 kilometers) northwest of Acapulco.
