A deposit of ash blankets the countryside around El Chichón volcano, seen in the background, on April 19, 1982, about two weeks after a series of major eruptions. Ash covered an area of more than 45,000 sq km in a ENE-trending lobe. At this location, 12 km NE of El Chichón, the ashfall deposit was 30 cm thick. Fine ash and sulfuric-acid droplets from the 1982 explosive eruptions of El Chichón circled the globe and were responsible for brilliant sunsets in the northern hemisphere for the next few years.
