The reduction in stratospheric ozone observed at northern mid‐latitudes in late 1982 through 1983 following the volcanic eruption of El Chichón is investigated in terms of ozone loss through heterogeneous chemistry on the aerosol which formed in the stratosphere. According to the experts, it is one of the most active in the country, with its last eruption in 1982. A Master student from the Utrecht University (Huizinga, 2013, unpub. OurAmazingPlanet.com. The powerful 1982 explosive eruptions of high-sulfur, anhydrite-bearing magma destroyed the summit lava dome and were accompanied by pyroclastic flows and surges that devastated an area extending about 8 km around the volcano. Throughout 1980 and 1981 there were a number of earthquakes in the area. El Chichón is part of a geologic zone known as the Chiapanecan Volcanic Arc. This event instigated more research to improve our knowledge on its eruption history. It is the largest volcanic disaster in modern Mexican history.

El Chichon was believed to be an extinct volcano since it had been more than 600 years since it’s last eruption. Magma from the 1982 eruption of El Chichón is known to have 2–4 wt % H 2 O (Luhr et al., 1984; McGee et al., 1987). El Chichón is a complex of domes with a tuff ring, made of ejected volcanic material, located between the Trans-Mexican Volcanic Belt and the Central America Volcanic Arc. The caldera is about a kilometer wide and a few hundred meters deep. It was the worst volcanic disaster in Mexico's recorded history. The high water content would reduce the viscosity of the magma, compared with anhydrous magma ( Murase & McBirney, 1973 ), and may therefore aid in more efficient mixing between the trachyandesite and the basalt. Web. Before its devastating eruption in 1982, El Chichón Volcano was little known and did not appear on any listings of hazardous volcanoes. MSc thesis) was the first to derive a detailed petrological and geochemical record of the eruption history of El Chichón for the last 3000 years. This is a view of the El Chichon caldera, formed during the very explosive eruptions of late March and early April of 1982. Roderick S. Quiroz, The isolation of stratospheric temperature change due to the El Chichón volcanic eruption from nonvolcanic signals, Journal of Geophysical Research: Oceans, 10.1029/JC088iC11p06773, 88, C11, (6773-6780), (2012). The 1982 eruption of El Chichón is the largest volcanic disaster in modern Mexican history. El Chichón, also known as Chichonal, is an active volcano in Francisco León, north-western Chiapas, Mexico. Many and diverse papers were presented in 11 conference sessions, including several focusing on volcano hazards, risk A cumulative mass of almost 8 million tons of sulfur dioxide was injected into the stratosphere.

The powerful 1982 explosive eruptions of high-sulfur, anhydrite-bearing magma destroyed the summit lava dome and were accompanied by pyroclastic flows and surges that devastated an area extending about 8 km around the volcano.

Considering El Chichon’s history of past eruptions, the existence of a wide, shallow, groundwater table and the re-establishment of an active hydrothermal system after the 1982 eruption, the probability of a new phreatic/phreatomagmatic eruption may still exist.
