Mexico Earthquake: Magnitude 5.7 Tremor Reported

A magnitude 5.7 earthquake struck southern Mexico on February 8, 2026, with tremors felt as far away as Mexico City, according to reports from the National Seismological Service and the European-Mediterranean Seismological Centre (EMSC).

The epicenter of the quake was located approximately 9 kilometers southwest of Miahuatlan de Porfirio Diaz, in the state of Oaxaca, at a depth of 49 kilometers, the EMSC reported. Earlier reports from Quakepulse.com and Earthquakelist.org pinpointed the epicenter closer to Santo Tomás Tamazulapam, with a shallower depth of 20 kilometers. The German Research Centre for Geosciences (GFZ) also registered the earthquake as a magnitude 5.7.

The earthquake occurred at 3:42 pm local time (21:42 UTC), according to Earthquakelist.org. While the initial magnitude is significant, seismologists anticipate potential revisions to the magnitude, epicenter, and depth as data is further analyzed and refined.

Limited Damage Expected, But Shaking Felt Across Region

Preliminary assessments suggest the earthquake is unlikely to have caused significant structural damage, with the primary impact expected to be limited to objects falling from shelves and broken windows. However, the quake was reportedly felt across a wide area, impacting several towns and cities in Oaxaca state and beyond.

According to VolcanoDiscovery, light shaking was likely experienced in Miahuatlan de Porfirio Diaz (population 23,900), Ocotlan de Morelos (population 15,000), Puerto Escondido (population 29,900), Crucecita (population 15,100), San Antonio de la Cal (population 20,200), and Santa Cruz Xoxocotlan (population 67,100). Weaker shaking may have been felt in Oaxaca city (population 255,000), located 89 kilometers from the epicenter.

Economic Impact Remains Unclear

The USGS has classified the risk of high fatalities as “GREEN” (low), estimating a 65% probability of between 0 and 1 fatalities and a 96% chance that the death toll will not exceed 10. The estimated economic impact is also classified as “GREEN” (low), with a 65% likelihood of between 0 and $1 million USD in damages and a 96% probability that the total economic impact will remain below $10 million USD. These figures are, however, preliminary and subject to change as damage assessments are completed.

The shallow depth of the earthquake, as reported by Earthquakelist.org at 20 kilometers, typically amplifies its impact, but the moderate magnitude and location away from major population centers have likely mitigated the potential for widespread devastation. The EMSC’s reported depth of 49 kilometers suggests a potentially reduced impact, though this discrepancy highlights the ongoing refinement of data.

Mexico’s Seismic Activity

Mexico is situated in a highly seismically active region, lying near the boundary of the Pacific and North American tectonic plates. Earthquakes are a relatively frequent occurrence, particularly along the country’s Pacific coast. A separate report from Cedarnews.net details a magnitude 5.7 quake in Santa Rosalía, Baja California Sur, Mexico, though this appears to be a separate event from the Oaxaca quake. The Santa Rosalía quake prompted emergency response evaluations, but no serious injuries or major structural damage were immediately confirmed.

Authorities in Oaxaca are currently assessing buildings and infrastructure for damage. Residents are encouraged to report their experiences through reporting mechanisms provided by VolcanoDiscovery and Earthquakelist.org, which will help provide more first-hand updates. Seismologists are continuing to monitor the region for potential aftershocks.

While the immediate economic impact appears limited, the earthquake serves as a reminder of the seismic risks facing Mexico and the importance of robust building codes and disaster preparedness measures. Further updates will be provided as more information becomes available from official sources.
