A magnitude 5.3 earthquake occurred 87 kilometers west-southwest of Puerto Madero, Mexico, at a depth of approximately 35 kilometers, according to the U.S. Geological Survey. This moderate-strength quake struck in a seismically active region along Mexico’s Pacific coast.
What You Might Notice
Residents within 100-150 km of the epicenter likely felt noticeable shaking—the kind that moves objects on shelves and causes people to pause momentarily. Farther away, shaking would have been gentler. At magnitude 5.3 and this depth, significant structural damage is unlikely in well-built areas, though older or poorly constructed buildings could experience minor cracking or loosening of fixtures.
Who Is Affected
Puerto Madero and surrounding communities in Chiapas state are in the primary impact zone. Coastal areas and nearby inland regions should monitor official channels for any damage reports or aftershock activity. Mexico’s monitoring agencies are the primary source for localized impact assessments.
Practical Steps to Take
Check in with contacts: If you have family or friends in the region, a simple text message can confirm everyone is safe without overloading local communication networks.
Watch for aftershocks: Magnitude 5.3 earthquakes sometimes trigger smaller aftershocks in the hours and days following. Aftershocks are typically weaker but can destabilize already-damaged structures.
Review your earthquake readiness: This is a good reminder to ensure your home’s heavy furniture is secured, you know how to turn off gas if needed, and your household has an accessible emergency kit with water, first aid supplies, and a battery-powered radio.
