Overview
- The Servicio Sismológico Nacional logged a series of low-magnitude earthquakes across several states on July 4–5, with the largest a magnitude 3.9 recorded 65 km southwest of Huixtla, Chiapas.
- Recorded magnitudes in the sequence ranged about 3.5–3.9 and depths varied widely from roughly 3 km to 132 km, a factor officials cite to explain why some quakes were felt locally while others were not.
- Protección Civil teams in affected states carried out routine inspections after the events and reported no significant structural damage or injuries.
- The SSN continued 24-hour monitoring after the cluster and officials urged the public to follow official SSN and Protección Civil channels for verified updates and preparedness guidance.
- Mexico’s location on active plate boundaries, including the Cocos and North American plates, makes frequent small quakes normal and there is no current scientific method to predict larger earthquakes so preparedness remains the priority.
