Although the volume of the eruption was small (< 1 cubic km of alkalic trachyandesite tephra, similar in volume to Mount St. Helens), El Chichon was also notable because it released an unusually large volume of aerosols (7 Mt of SO2 compared to 1.0 for Mount St. Helens). Prior to 1982, this relatively unknown volcano was heavily forested and of no greater height than adjacent nonvolcanic peaks. An AVHRR weather satellite image, both visible and thermal, of the April 4, 1982 plume from El Chichon in Mexico. Major pyroclastic (volcanic rock) erosion has taken place in Chiapas from time to time since the eruption.

El Chichón volcano After several months of increased seismic activity. It's history, eruptions, latest news, pictures + some facts and info about. This volcano was naturally made within a 1.6 x 2km crater which was made approximately 220,000 years ago. Mexico is near the edge of the North American plate at a convergent boundary meeting up with Cocos Plate and that could of influenced the eruption. Apr. El Chichon was the first major eruption to have its atmospheric effects studied in detailed by modern instruments. El Misti’s most recent—and relatively minor—eruption occurred in 1985. Earth's Plates Volcano Type El Chichon is located on a convergent plate boundary, also know as a destructive plate boundary.
El Chichon is still effecting our earth today. El Chichón is a small, but powerful trachyandesitic tuff cone and lava dome complex that occupies an isolated part of the Chiapas region in SE México far from other Holocene volcanoes. El Chichon is not a hot spot or on a diverging plate boundary. This volcano is explosive, so it erupted volcanic ash and pyroclastic material. The El Chichon volcano is located in Mexico near a state named Chiapas.

Stratovolcanoes are usually located on the continental crust above a subducting tectonic plate.

It El Chichon El Chichon was made on a convergent boundary. The Volcano El Chichon, Mexico: El Chichon is the most southern and eastern volcano in Mexico. Fun Facts; Bibliography; Fun/Interesting Facts-it means "the bump"-it has a pattern of eruptions-thought to be extinct-1982 eruption killed 2000 people-small but powerful-erupted constantly from March 28 to April 4 1982 -it is the most southern and eastern volcano in Mexico

The El Chichon volcano complex in Chiapas, Mexico, as seen on March 11, 1986, when the devastation of the 1982 eruption is still clear. The Chiapanecan Volcanic Arc, which includes El Chichón, falls outside Mexico’s Volcanic Axis (the location of almost all Mexico’s volcanoes) and is thought to be related to the subduction of the edge of the Cocos Plate underneath the North American plate.
