The stratospheric dust cloud from the 4 April 1982 eruption of El Chichón volcano in southern Mexico was observed to travel completely around the world in a 3-week period. Images from satellites operated by the National Oceanic and Atmospheric Administration were used to prepare daily maps of the location of the volcanic dust cloud, which is the largest and longest-lasting one so far observed with satellite imagery.
