A geologist surveys the enlarged crater of Cerro Negro volcano in December 1972, observing the effects of the previous eruption during February 3-14, 1971.  Powerful explosions substantially enlarged the summit crater from 150 m in diameter before the eruption to 400 m after it.  This highly explosive eruption produced ashfall that caused extensive crop damage over a 5000 sq km area. Photo by Dennis Nielson, 1972 (courtesy of Mike Carr, Rutgers University).
