Seismic activity has remained present in Mexico with earthquakes of magnitude between 4.0 and 4.1 Earthquakes have been recorded in various states across the country in recent days, according to reports from the National Seismological Service (SSN). This monitoring compiles the latest data for those seeking information. Where and at what time did the earthquake occur today in Mexico?.
In this informational section, we have compiled the times, epicenters and depths Statements from the SSN, along with a brief explanation of the causes of seismic activity in Mexico and safety recommendations. The information is presented clearly so you can Quickly check the busiest areas.

According to initial reports, No damage has been confirmed No significant materials or people were affected in these events; the authorities are maintaining their usual monitoring of the areas near the epicenters.
Detailed Epicenters and Magnitudes
The events with the most precise location were concentrated in the south and southeast of the country. OaxacaThe earthquake at 15:21 p.m. on October 28 was located 28 km NE of Unión Hidalgo, with approximate coordinates 16.71°N, -94.733° and a depth of ~109.4 km. Another record in the state, at 17:19:33 h on October 29, was located 66 km NE of Matías Romero (latitude ~17.26°, longitude ~-94.57°) with a depth of ~157 km.
En VeracruzThe movement at 22:14 on October 29 was reported to 41 km south of Jáltipan de Morelos, with latitude ~17.599° and longitude ~-94.663°, at a depth of ~154.7 km; additionally, at 01:42 h on October 31, another earthquake of magnitude 4.1 was recorded. 51 km south of Minatitlán, at a depth of ~162.4 km. This record reflects the continued seismicity in Mexico.
En ChiapasTwo records close to the coast stand out: one at 00:47 on October 31 and another at 06:47 on the same day, both 134 km southwest of TonaláThe first one had a depth of approximately 16.8 km with coordinates ~14.985°N, -94.279°The second one occurred in the same area. A 4.1 magnitude earthquake was also reported. 76 km SW of Ciudad Hidalgo (02:24 h), with a depth of ~15 km.
Outside the south-southeast strip, the event in Cihuatlán (Jalisco) At 00:19 on October 29, it reached a magnitude of 4.1, and remained within the seismicity range. typical for the Mexican Pacific region.
Why are there so many earthquakes in Mexico?
La geographical position of Mexico This explains the frequency of earthquakes. The territory sits atop the interaction of multiple tectonic plates: North America, Caribbean, Cocos, Pacific and Riviera, whose contact generates energy releases that we perceive as earthquakes.
In particular, the Cocos Plate subduction The North American Plateau off the Pacific coast is a key source of seismicity, while the areas near Oaxaca, Chiapas, and Guerrero often experience activity due to the complex geological formations. regional tectonic dynamics.
Can earthquakes be predicted?
Today, There is no scientifically validated method all with anticipate earthquakes with precision when and where they will occur. The scientific community is working to improve the risk assessment and early warningsbut not in exact predictions.
Regarding measurement, the old scale of Richter (1935) was surpassed by the moment magnitude (Mw, 1979)which better reflects the energy released, especially in medium and large earthquakes. Even so, for moderate tremors, both references usually offer comparable valuesFor more details, see the differences between tremors and earthquakes.
Safety recommendations
During an earthquake, stay calm and look for a safe place inside the house (under a sturdy table or next to a structural wall). Stay away from windows, objects that could fall, and do not use elevators.
If you're on the street, move towards open areas, away from building facadestrees and poles. If you are driving, stop in a safe place, with turn signals onavoiding bridges and tunnels.
After the movement, check for injuries, shut off the gas supply if you detect any odor or leaks, and follow the Official information from the SSN and Civil ProtectionKeep an emergency kit with water, a flashlight, a radio, a charger, and basic medication.
Based on the available data, the day has shown moderate and distributed seismic activity in several states, with no reports of significant damage. Official monitoring and citizen preparedness remain the best tools for Living with seismic risk in Mexico.
