Mexico Earthquake: Map Shows Where 7.3 Magnitude Tremor Hit Coastline

A powerful magnitude 7.3 earthquake struck off the southern coast of Mexico early Friday morning, rattling the region and triggering immediate infrastructure reviews by emergency officials.

The U.S. Geological Survey (USGS) said the quake struck near the Pacific coast of Chiapas state. The tremor occurred at a shallow depth, a factor that typically amplifies the intensity of shaking and expands the area where it can be felt.

Newsweek reached out to the USGS by email for comment.
