Steam clouds fill much of the crater of San Cristóbal volcano in March 1976. After a quiescence of about five years, small ash eruptions took place at San Cristóbal on March 9-10, 1976, dropping ash on the nearby town of Chinandega. During an eruption on March 16 ash was confined primarily to the summit crater area. The summit crater of San Cristóbal is 500-600 m wide.
