1. Understanding Mexico’s Tectonic Setting
Why Are Earthquakes So Common In Mexico? The answer lies in its complex tectonic setting. Mexico is situated on five tectonic plates: the North American, Cocos, Pacific, Rivera, and Caribbean plates.
1.1. Plate Interactions
These plates interact in various ways, including:
- Subduction: The Cocos Plate subducts (slides) beneath the North American Plate along the Pacific coast of Mexico.
- Transform Boundaries: Plates slide past each other horizontally, creating friction and stress.
- Divergent Boundaries: Plates move away from each other, leading to volcanic activity and earthquakes.
This complex interaction results in frequent seismic activity throughout the country.
1.2. The Cocos Plate and Subduction
The subduction of the Cocos Plate beneath the North American Plate is a primary driver of earthquakes in Mexico. As the Cocos Plate descends, it generates immense pressure and friction, leading to sudden releases of energy in the form of earthquakes.
1.3. Vulnerable Regions
Certain regions of Mexico are more prone to earthquakes due to their proximity to active tectonic zones. The Pacific coast, particularly south of Puerto Vallarta, is highly susceptible to shaking because of the Cocos Plate subduction.
2. Seismic Activity in Mexico: A Historical Perspective
Why are earthquakes so common in Mexico historically? Mexico has a long history of seismic activity, with numerous significant earthquakes recorded over the centuries. Understanding this history helps to contextualize the current situation.
2.1. Notable Earthquakes
Some of the most notable earthquakes in Mexico’s history include:
- 1985 Mexico City Earthquake: This magnitude-8.1 earthquake caused widespread destruction and loss of life in Mexico City.
- 2017 Tehuantepec Earthquake: A magnitude-8.2 earthquake that struck off the coast of Chiapas, causing significant damage.
- 2017 Puebla-Morelos Earthquake: A magnitude-7.1 earthquake that occurred shortly after the Tehuantepec earthquake, causing further devastation.
- 2022 Michoacan Earthquake: A magnitude-7.7 earthquake that shook the Michoacan coast.
These events underscore the ongoing seismic risk in Mexico.
2.2. Earthquake Catalogs
Researchers and seismologists maintain earthquake catalogs to track and analyze seismic activity over time. These catalogs provide valuable data for understanding earthquake patterns and assessing risk.
2.3. Data Analysis
Analyzing historical earthquake data helps to identify trends and patterns, although predicting the exact timing and magnitude of future earthquakes remains a challenge.
3. Why September Isn’t Necessarily “Earthquake Month”
Why are earthquakes so common in Mexico, and why do they seem to happen in September? Despite recent coincidences, data suggests that September is not inherently more prone to earthquakes.
3.1. The “Earthquake Month” Myth
The perception of September as “earthquake month” has been reinforced by several significant earthquakes occurring in that month in recent years. However, this is largely a statistical coincidence.
3.2. Analyzing Earthquake Frequency
Analysis of earthquake catalogs reveals that earthquakes occur throughout the year, and there is no statistically significant increase in frequency during September.
3.3. Data from 1787 to 2022
A study of earthquakes in Mexico between 1787 and 2022 found no evidence to support the idea that September is more earthquake-prone. In fact, other months, such as April and December, have experienced more date coincidences of earthquakes.
4. Tectonic Plates and Earthquake Causes
Why are earthquakes so common in Mexico due to its location relative to tectonic plates? The interaction of tectonic plates is the primary cause of earthquakes in Mexico.
4.1. Plate Boundaries
Mexico is located near the boundaries of five tectonic plates:

- Cocos Plate: An oceanic plate that subducts beneath the North American Plate.
- Pacific Plate: A large oceanic plate that interacts with the North American Plate along transform faults.
- Rivera Plate: A small oceanic plate that is subducting beneath the North American Plate.
- Caribbean Plate: A mostly oceanic plate underlying the Caribbean Sea and adjacent land areas.
4.2. Subduction Zones
The subduction of the Cocos Plate beneath the North American Plate creates a subduction zone along Mexico’s Pacific coast. This process is responsible for many of the country’s largest earthquakes.
4.3. Fault Lines
Fault lines are fractures in the Earth’s crust where movement occurs. Mexico has numerous active fault lines that contribute to seismic activity.
5. Seismic Zones in Mexico
Why are earthquakes so common in Mexico in specific zones? Mexico is divided into several seismic zones, each with different levels of earthquake risk.
5.1. High-Risk Zones
High-risk seismic zones include:
- Pacific Coast: The coastal regions of Oaxaca, Guerrero, and Michoacan are particularly vulnerable due to the subduction of the Cocos Plate.
- Mexico City: Despite being located inland, Mexico City is susceptible to earthquake damage due to its soft soil, which amplifies seismic waves.
5.2. Moderate-Risk Zones
Moderate-risk zones include:
- Central Mexico: Regions such as Puebla and Morelos have experienced significant earthquakes in the past and remain at risk.
5.3. Low-Risk Zones
Low-risk zones include:
- Northern Mexico: The northern states generally experience fewer earthquakes compared to the southern and central regions.
