A strong steam plume pours from the summit crater of San Cristóbal volcano in this March 1976 view from the NW.  Mild explosive eruptions during March 9-16, 1976 were the first since 1971.  In February 1972 part of the crater floor began subsiding, ultimately leading to formation of a collapse pit in March 1976.  By December 1976 the pit had deepened to 90 m and incandescence was visible after dark. Copyrighted photo by Dick Stoiber, 1976 (Dartmouth College).
