[5] Generally a volcanic event would induce global cooling, particularly in summer months, however no cooling was seen in the first year after the El Chichón eruption, because the El Niño produced large compensating warming. [7], The imaginary part of the refractive index, describing the attenuation of radiation for the 80 km sample, varies between 0.004 at 300 nm and 0.001 at 700 nm. Key words: El Chichón volcano, tephrochronology, palynology, late holocene eruptions, maya lowlands, Mexico.

[8], The non-soluble part consists mostly of SiO2 (around 59%) and Al2O3 (around 18%) along with trace amounts (less than 5%) of other components, such as CaO, Na2O and Fe2O3. Today it consists of a 1km wide, 300m deep crater with a crater lake that strongly signifies recent volcanic activity 1. [8], For the El Chichón cloud, the optical depth has been measured to be around 0.3 around mid-visible wavelengths. A cumulative mass of almost 8 million tons of sulfur dioxide was injected into the stratosphere. The column reached a height close to 30 kilometer.

Only after these explosions a surge of new studies began to unreveal their volcanic history and impact. The 1982 eruption of El Chichón volcano ejected more than 1km 3 of anhydrite-bearing trachyandesite pyroclastic material to form a new 1-km-wide and 300-m-deep crater and uncovered the upper 500m of an active volcano-hydrothermal system. Most presumed it to be a dormant volcano or extinct. It is a small, but powerful andesitic tuff cone and lava dome complex that occupies an isolated part of the Chiapas region far from other Holocene volcanoes.

El Chichón, also known as Chichonal, is an active volcano in Francisco León, north-western Chiapas, Mexico. The origin of El Chichón volcano is poorly understood, and we attempt in this study to demonstrate that the Tehuantepec Ridge (TR), a major tectonic discontinuity on the Cocos plate, plays a key role in determining the location of the volcano by enhancing the slab dehydration budget beneath it. [2] 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. El Chichón erupted in 1982; prior to this, activity had not occurred since c.1360, although debates in literature occur around an eruption occurring in c.1850. El Chichón is built on Tertiary siltstone and sandstone, underlain by Cretaceous dolomitic limestone; a 4-km-deep bore hole near the east base of the volcano penetrated this limestone and continued 770 m into a sequence of Jurassic or Cretaceous evaporitic anhydrite and halite.
