Volcanoes

Image
Mexico has 37 Holocene volcanoes which are inactive and 12 active volcanoes. The three most active volcanoes in the country are the Popocatepetl, Colima, and El Chichon.  Almost all of the country's active and recently dormant volcanoes are located in a broad belt of high relief that crosses Mexico from west to east: the Volcanic Axis. Altitudes in this region vary from a few hundred to several thousand meters.  The Citlaltépetl (Pico de Orizaba) is the highest volcano in Mexico with an elevation of 5,675 meters above sea level!    The best way to do protect yourself and your family is to follow the advice of local officials. Local authorities will provide you with information on how to prepare for a volcanic eruption, and if necessary, on how to evacuate (leave the area) or take shelter where you are.   Be prepared to:  Shelter in place and close all windows/turn off ventilation. You will need to protect yourself from any hazardous fumes.  Drive/evacu...

Seismicity

Image
The country of Mexico sits on the world’s most seismically active zone, the Ring of Fire. Mexico has a complex landscape making it vulnerable to a variety of natural disasters and is particularly prone to earthquakes and volcanic activity. Most of the country sits atop the North American Plate and the undersea Cocos Plate in the Pacific Ocean is constantly trying to push below the North American Plate causing tension. Within this zone is a section of a fault known as the Guerrero Gap that stretches 230 kilometers long from Acapulco to Papanoa. The Guerrero Gap has been “quiet” for over 100 years and specialists fear that the accumulation of energy throughout the years can trigger a large earthquake with the potential of severe damage at any point.  Mexico has 37 Holocene volcanoes which are inactive and 12 active volcanoes. The three most active volcanoes in the country are the Popocatepetl, Colima, and El Chichon.  In the event of an emergency, Mexico has educated its people ...

Tectonics

Image
Most of Mexico sits atop the North American Plate, but is also impacted by the Cocos Plate, and Pacific Plate (the three LARGEST tectonic plates). Mexico also touches the much smaller Caribbean Plate, the Pacific Plate, The Rivera Plate, and the Orozco Plate. This means that Mexico is one of the most seismically active countries in the world facing many earthquakes and volcanic activity. "Mexico sits in the world's MOST seismically and volcanically active zone, known as the Ring of Fire." The Baja California Peninsula is on the gigantic Pacific Plate which is part of the famous SAF (San Andreas Fault) system.  Mexico also has a "belt" of volcanoes that cross the country from West to East (see below). This is known as the Volcanic Axis, in which altitudes range from a few hundred to several thousand meters.  The aftermath of previous volcanic activity is found in craters, mud volcanoes, and numerous hot springs scattered throughout the Volcanic Axis, where a lot ...
