Earthquake Summary

This earthquake hit under water in the North Pacific Ocean, 78 kilometers (49 mi) off the coast of Mexico, 104 kilometer southwest of Tapachula in Chiapas. The center of this earthquake had a very shallow depth of 11 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

Minimal impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level GREEN (low). They expect an 90% likelyhood of between 0 and 1 fatalities.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 90% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.

Roughly 1 million people exposed to shaking

This earthquake may have been felt by around 1 million people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

An estimated 384,200 people were exposed to level IV. At this level, light shaking and likely no damage can be expected. Intensity level III was experienced by the majority of people (around 570 thousand). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. In Mexico , around 750 thousand people, with impact levels up to IV (light shaking, likely no damage). In Guatemala , around 210 thousand people.

Nearby towns and cities

Mexico and Guatemala are both located within 300km distance of the epicenter of the earthquake.

The closest significant population center near the earthquake is Tapachula in Chiapas, Mexico. Tapachula is located 104 kilometer (65 mi) southwest of the epicenter. The intensity of shaking and damage in Tapachula is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

Multiple major population centers exist within 300km of the earthquake that struck today. Guatemala City is located 272 km to the east (intensity unknown, possibly low). Tuxtla is located 271 km to the north (intensity unknown, possibly low). Tapachula is located 104 km to the north-east and experienced an intensity of III (weak shaking, probably no damage).

An overview of nearby towns and cities is available in the overview below. If places don't have intensity data available, it likely means the experienced impact in those places was fairly small.

31 Aftershocks detected

Since this main shock, 31 smaller aftershocks were detected. At a distance of 57 km (35 mi) northwest of this earthquake, an aftershock struck 22 hrs later. It measured a magnitude of 4.3

Before this earthquake struck, 18 smaller foreshocks occurred. Nearby this earthquake a foreshock struck 17 hrs earlier. It measured a magnitude of 4.3

Overview of foreshocks and aftershocks

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major earthquake.

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since August 18th, 2026, when a 5.8 magnitude earthquake hit 21 km (13 mi) further southwest. An even stronger magnitude 8.2 earthquake struck on September 8th, 2017.

In total, 44 earthquakes with a magnitude of 5.6 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 3 months.

Low tsunami risk

Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so stay cautious and monitor advice from local authorities.
