A vigorous steam plume pours from Masaya volcano in this November 9, 1984 Space Shuttle image taken near the end of a two-decade-long eruptive episode. North lies to the lower right, with Lake Nicaragua at the lower left and Lake Managua at the lower right. To the left of the plume from Santiago crater is Lake Masaya (ponded against the rim of Masaya caldera) and the circular lake-filled Apoyo caldera. The two caldera lakes at the lower right are Apoyeque (light blue) and Jiloa (dark-colored), across the bay from the city of Managua.
