Mexico Earthquake: 4.0 Magnitude Tremor in Guerrero Jan 6

Seismic Activity Rises in Mexico: Multiple Earthquakes Recorded on January 6, 2026

A series of earthquakes, including a 4.0 magnitude tremor in San Marcos, Guerrero, rattled parts of Mexico on January 6, 2026, prompting ongoing monitoring from authorities adn recommendations for public preparedness. While no immediate damage or effects were reported from the initial 4.0 magnitude quake, the National Seismological Service documented a broader pattern of seismic activity across several regions.

Guerrero Remains Epicenter of Activity

The majority of the recorded movements centered around the state of Guerrero, specifically near Saint Marcos. These tremors ranged in magnitude from 3.0 to 3.9,with a separate 3.3 magnitude earthquake reported near Altamirano City. according to the National Seismological Service, these earthquakes originated at relatively shallow depths, between 5 and 15 kilometers, perhaps increasing their perceptibility.

The most frequent tremors were located southwest and west of San Marcos, Guerrero. A 3.3 magnitude earthquake was also detected southwest of Ciudad Altamirano.

Did you know? – Mexico sits atop a complex network of tectonic plates, making it one of the most seismically active regions in the world. This geological setting explains the frequent earthquakes.

Widespread, Though mostly Minor, Tremors Across Mexico

beyond Guerrero, smaller earthquakes were detected in several other areas:

• Baja California Sur: Several minor earthquakes, ranging from 1.6 to 2.0 in magnitude, were recorded at depths of 10 to 14 kilometers.
• Oaxaca: Earthquakes of 3.7 and 3.8 magnitude were reported in Matias Romero and Salina Cruz, respectively.
• Chiapas: two 4.0 magnitude earthquakes were recorded in Tonalá and Pijijiapan.
• Baja California: Earthquakes of 3.3 and 3.4 magnitude were detected in San Felipe.
• San Luis Potosi & Jalisco: Movements of 3.7 and 4.0 magnitude were recorded in cardenas and Cihuatlán, respectively.

Pro tip – Secure heavy objects in your home, like bookshelves and water heaters, to prevent them from falling during an earthquake.This simple step can significantly reduce injury risk.

Aftershocks continue Following Recent Major Earthquake

the recent activity comes as Guerrero continues to experiance aftershocks from a larger 6.5 magnitude earthquake that struck San Marcos on January 2, 2026. As of 8:00 a.m. on January 6,2026,a staggering 2,966 aftershocks had been recorded,the largest reaching a magnitude of 4.7.

Understanding mexico’s Seismic Landscape

Mexico’s location within a highly active seismic zone is due to the presence of five major tectonic plates – the Caribbean, North America, Pacific, Rivera, and Cocos plates – beneath its territory. The constant interaction between these plates results in frequent seismic activity. “The country is situated in an area of high seismicity,” one analyst noted,emphasizing the inherent geological risks.

Mexico Experiences Increased Seismic Activity – January 6, 2026

Mexico City, Mexico – A series of earthquakes rattled several regions of Mexico on January 6, 2026, with the most significant tremor registering a magnitude of 4.0 in San Marcos, Guerrero. The National Seismological Service (SSN) has been closely monitoring the increased activity,and authorities are urging the public to remain prepared.

what Happened? The series of earthquakes began with a 4.0 magnitude quake in San Marcos, Guerrero, and were followed by numerous smaller tremors across the country. The SSN recorded a total of 2,
