A vigorous white steam plume, seen here from the NW, rises from the summit crater of San Cristóbal volcano in March 1976. Small ash eruptions occurred from San Cristóbal on March 9-10, 1976, dropping ash on the town of Chinandega, 10 km to the SW. Ashfall from another eruption on March 16 was restricted to the summit crater area. Collapse of cones within the summit crater during this eruption created a new 300-m-wide vent.
