Earthquakes in Oaxaca Region

A series of light earthquakes struck the Oaxaca region on Thursday, Nov 12, according to VolcanoDiscovery. The strongest was a magnitude 4.0 event 42 km southwest of Tonala, Mexico, at 11:28 am local time.

The quakes were widely felt across the state, with reports from multiple locations including Salina Cruz and Arriaga, per VolcanoDiscovery. No casualties or significant damage have been reported so far.

Oaxaca's proximity to the Pacific Ocean makes it vulnerable to seismic activity; the region’s geology includes active fault lines that frequently produce minor tremors. The US Geological Survey noted these events as typical for the area.
