Active Fault Systems & Tectonic Setting
Geodynamic boundaries, subduction dynamics, and crustal deformation zones.
Mexico lies along a highly active subduction zone where the Cocos and Rivera Plates slide beneath the North American Plate along the Middle America Trench. This tectonic boundary generates frequent high-magnitude earthquakes and triggers early warning alerts via SASMEX.
Middle America Trench (MAT)
Subduction MegathrustPrimary convergent interface generating frequent M7.5+ megathrust events along Guerrero, Oaxaca, and Michoacán.
Trans-Mexican Volcanic Belt Faults
Extensional & Strike-SlipIntraplate volcanic arc faulting stretching east-west across central Mexico.
Guerrero Seismic Gap
Subduction Locked Zone200 km segment along the Pacific coast with elevated accumulated strain monitored closely by SSN.
Landmark & Historical Earthquakes
Significant seismic benchmarks, cataloged magnitudes, and geological impacts.
Michoacán Coast, Pacific Mexico
September 19, 1985Subduction megathrust that resonated catastrophic 2-second wave amplification in Mexico City's soft lakebed.
Gulf of Tehuantepec, Chiapas
September 7, 2017Strongest Mexican earthquake in a century; intraslab normal rupture 47 km deep affecting Oaxaca and Chiapas.
Puebla-Morelos Border
September 19, 2017In-slab intraslab earthquake 57 km deep; triggered building collapses across Mexico City on the 1985 anniversary.
Frequently Asked Questions
Common questions about seismic activity, safety, and monitoring in Mexico.
How does the SASMEX seismic alert siren work in Mexico?▾
SASMEX sensors along the Pacific subduction coast detect primary P-waves and transmit radio signals to Mexico City, Guadalajara, and Puebla, providing 20 to 120 seconds of warning before destructive S-waves arrive.
Why does Mexico City shake so violently from distant earthquakes?▾
Mexico City is built on unconsolidated clays and soft lakebed deposits of ancient Lake Texcoco, which trap and amplify low-frequency seismic waves by a factor of 8 to 50 times compared to solid bedrock.
What is the Guerrero Seismic Gap?▾
The Guerrero Gap is a 200 km section of the Middle America Trench near Acapulco that has not produced a major subduction megathrust since 1911, making it a focal point of intense geodetic and seismic monitoring.
