Mexico experiences practically continuous seismic activity due to its location in the Pacific Ring of Fire, one of the most tectonically active zones in the world.In this context, various lithospheric plates converge and interact, including the Cocos, North America, Pacific, Rivera, and caribbean plates, configuring a complex geodynamic habitat that places the country among those with the highest seismic hazard globally (National Seismological Service, UNAM).
Most of the moderate to large magnitude earthquakes recorded in Mexico are related to the subduction process of the Cocos plate under the North American plate along the Pacific coast. Though, some seismicity originates in internal faults of the continental crust, capable of generating shallow events that, depending on their magnitude and proximity to urban centers, can be perceptible. for this reason, entities such as Oaxaca, Guerrero, Chiapas, Michoacán, Colima, Jalisco and baja California are classified as regions of high seismic activity and recurrent exposure to tectonic deformation.
Operational statistics from the National Seismological Service (SSN) confirm that earthquakes occur daily in Mexico. Numerous events of low and medium magnitude are recorded each day, most of them imperceptible to the population. The extensive network of seismological stations distributed throughout the national territory allows the identification of thousands of earthquakes per month, many of them with magnitudes less than 4.0,which demonstrates frequent and persistent seismicity,consistent with the country’s tectonic position.
In this context, so-called microseisms become relevant, defined by the SSN as events of very small magnitude, generally less than 3.0. Although rarely felt by the population, their registration and analysis are basic for the characterization of the subsoil. In Mexico city, these microseisms have been associated with local faults located mainly in the western and southern sectors of the capital.These are shallow earthquakes, of short duration and low intensity, which provide key facts about the geological structure of the Valley of Mexico and contribute to the improvement of seismic hazard models in densely populated urban areas.
Seismicity also coexists with other relevant geological phenomena, particularly volcanism. In this regard, the Ej

FAQ: Preguntas frecuentes sobre sismos en México
¿Por qué tiembla tanto en México?
Porque el país se encuentra sobre el Cinturón de Fuego del Pacífico, donde interactúan varias placas tectónicas (Cocos, Norteamérica, Pacífico, Rivera y Caribe), lo que genera una alta actividad sísmica.
¿Qué estados de México son más propensos a sismos?
Principalmente los ubicados en la costa del Pacífico: Oaxaca, guerrero, Chiapas, Michoacán, Colima, Jalisco y Baja California, aunque los efectos de los sismos pueden sentirse en otras regiones del país.
¿Qué es un microsismo?
Es un sismo de muy baja magnitud, generalmente menor a 3.0, que casi nunca es percibido por la población y rara vez genera daños. Son comunes en zonas como la Ciudad de México.
¿Se pueden predecir los sismos en México?
No. Hasta ahora no existe un método científico confiable para predecir con exactitud la fecha, hora y magnitud de un sismo. Lo que sí se puede hacer es estimar la peligrosidad sísmica de una región y contar con sistemas de alerta temprana.
¿Qué diferencia hay entre temblor y sismo?
Ninguna.Ambos términos se usan para describir el mismo fenómeno: la liberación repentina de energía en la corteza terrestre que genera ondas sísmicas.

Source text: “No existe una periodicidad exacta. Sin embargo, la historia sísmica del país muestra la ocurrencia recurrente de sismos de gran magnitud, por lo que la preparación y la prevención deben ser permanentes.” (Translation: “There is no exact periodicity. However, the seismic history of the country shows the recurring occurrence of large-magnitude earthquakes, so readiness and prevention must be permanent.”)
Verification & Updates:
The statement that there is no exact periodicity for major earthquakes in Peru is verified by multiple authoritative sources. Peru is located in a highly seismically active zone, a subduction zone where the Nazca Plate subducts under the South American Plate. This geological setting results in frequent earthquakes, but predicting when a large earthquake will occur remains unachievable.
* Instituto Geofísico del Perú (IGP): The IGP (Peruvian Geophysical Institute) consistently emphasizes the lack of earthquake prediction capabilities and the importance of preparedness. (https://www.igp.gob.pe/)
* US Geological Survey (USGS): The USGS also confirms the complex seismic activity in Peru and the inability to predict earthquakes. (https://earthquake.usgs.gov/regions/peru/)
* Historical Data: Historical records of earthquakes in Peru demonstrate irregular intervals between major events. Meaningful earthquakes have occurred in 1960 (Great Chilean Earthquake impact),1970 (Ancash earthquake),2007 (Pisco earthquake),and 2019 (Peru-Ecuador border earthquake).these events do not follow a predictable pattern.
Breaking News Check: As of January 17, 2026, there have been no major, breaking news reports of a significant earthquake in Peru that contradict the statement about the lack of predictability. Routine seismic activity continues to be monitored by the IGP. There have been ongoing public awareness campaigns regarding earthquake preparedness, consistent with the source’s suggestion for permanent preparation and prevention.
Latest Verified Status: The statement remains accurate and current as of January 17, 2026. the lack of a predictable earthquake cycle in Peru is a well-established scientific fact, and preparedness remains crucial.
