MEXICO CITY (AP) — A magnitude 6.2 earthquake struck a region of southwestern Mexico early Sunday, causing no serious damage or casualties, according to the United States Geological Survey.

It said the quake struck 21 kilometers (13 miles) southeast of Aquila, near the border of the states of Colima and Michoacán, at a depth of 34 kilometers (21 miles).

Mexican President Claudia Sheinbaum said on the social media platform X that the quake had prompted emergency teams to review their protocol.

“There are no new developments,” she wrote. Mexico’s Social Security Institute said there were no reports of damage in the capital Mexico City, about 600 kilometers (372 miles) east of the quake’s epicenter – near the mountain village of Coalcomán in Michoacán.

Some people in Coalcomán and in Uruapan, Michoacán’s second-largest city, posted surveillance footage on social media with a timestamp of 2:32 a.m. local time that showed buildings swaying and parked cars shaking. Others reported running into the street to wait for the shaking to stop.

Mexico’s national seismological service said there were 329 aftershocks as of 9 a.m. local time on Sunday. The magnitude was estimated at 6.1. It is not uncommon for preliminary measurements to vary.

Mexico is no stranger to earthquakes due to its location near colliding parts of the Earth’s crust. There have been at least seven quakes of magnitude 7 or higher in the past 40 years, killing around 10,000 people – most of them in a devastating magnitude 8.0 quake in 1985.
