El Chichón data

Conference Proceeding

Publication Date



The March–April 1982 eruptions of El Chichón have produced the largest atmospheric impact of any eruption since at least Krakatau in 1883. The main geological variable that is responsible is the abnormally high S content of the erupted magma. The ultimate souce of this sulfur is still unresolved. Some highlights of the scientific papers dealing with the eruptions and presented at the AGU Fall Meeting in San Francisco, December 10–11, are discussed below. (The abstracts are in Eos, November 9, 1982, pp 897–898, 900–902, and 1126–1127.) ©1983. American Geophysical Union. All Rights Reserved.
