An incandescent pyroclastic flow (lower right) travels down the flanks of the volcano as lightning bolts accompany an eruption plume (center) from El Chichón on April 3, 1982. Minutes later this eruption column reached a height of about 24 km. The ejection of large amounts of incandescent tephra and pryoclastic flows and surges caused extensive damage and fatalities. Explosive removal of the summit lava dome created a new 1-km-wide, 300-m-deep crater.
