A minor magnitude 3.6 earthquake struck near GUERRERO, MEXICO on Tuesday, September 8, 2026 at 09:43:18 AM UTC. This shallow crustal event (26.7 km depth) released energy equivalent to approximately 4 tons of TNT. Here is the verified UNM telemetry, live epicenter map, and ground shaking assessment.

A magnitude 3.6 event is classified as a minor earthquake. Often felt by people indoors, especially on upper floors. Hanging objects may swing slightly; structural damage is extremely rare.
Felt by almost no one except under extraordinarily favorable conditions.

Earthquake strength is measured on a logarithmic scale. Compare this event with the full seismic scale:
Because seismic scales are logarithmic, each whole integer increase represents:
Southern and central Mexico lies directly above the Middle America Trench, where the oceanic Cocos and Rivera plates subduct beneath the North American Plate. This active subduction margin produces frequent intermediate and megathrust seismic events.
Originating at a depth of 26.7 km (Earth's Crust (0–70 km)), this rupture occurred occurred within the brittle upper crust. shallow earthquakes produce the highest peak ground acceleration and the sharpest surface shaking.
Seismologists note that minor aftershocks remain common in the 24 to 48 hours following tremors of magnitude 3.6. According to statistical seismic models, there is roughly a 5% probability of a subsequent event of equal or greater strength occurring in the same fault zone. Residents in Mexico are advised to check living spaces for unsecured items.
