Magnitude 4.3 earthquake recorded off Chiapas, Mexico

A magnitude 4.3 earthquake struck off Chiapas in southern Mexico on Nov.

1, according to the National Seismological Service.

Its epicenter was 68 kilometers southwest of Ciudad Hidalgo, at a depth of 11.5 kilometers.

The service also reported a separate magnitude 4.2 quake farther southwest, and said no damage or injuries were reported.

Mexico records about 60 to 80 earthquakes a day, with many concentrated in Oaxaca, Guerrero and Chiapas.

The quakes did not meet alert thresholds, so Mexico’s seismic warning system did not sound alarms; the reported movements were between magnitude 4.0 and 4.4.

Magnitude measures the energy released, while depth affects how strongly shaking is felt at the surface.

The seismic service continued monitoring activity across the country.
