Overview
- The national seismic network recorded a cluster of small earthquakes off Chiapas on Friday and Saturday, with magnitudes between about 3.7 and 3.9 and shallow focal depths.
- Local Protección Civil teams and federal agencies inspected nearby towns after the events and reported no casualties or significant infrastructure damage.
- UNAM's Instituto de Geofísica and the Servicio Sismológico Nacional reiterated that the timing is random and that no scientific method can predict the exact date, time or location of earthquakes.
- Scientists attribute the frequent low-magnitude activity to long-running plate interactions in Mexico's southern Pacific margin, especially the Cocos Plate subducting beneath the North American Plate.
- Authorities are using the recent detections to urge steady preparedness, to highlight SSN real-time monitoring for verified data, and to remind the public that daily microsismos are normal in the region.
