San Miguel is one of the most prominent volcanoes in El Salvador. Its southern slopes, seen here, rise more than 2000 m above the farmlands on the Pacific coastal plain. Both summit and flank vents have been active during historical time. The dark-colored lava flow at the right-center was erupted from a SE-flank vent in 1819.
