Details for: Izalco
The unvegetated slopes of Volcán de Izalco, seen here from the north, are those of El Salvador's youngest volcano. It originated in 1770 CE on the southern flank of Santa Ana volcano. Frequent strombolian eruptions from the volcano known as the "Lighthouse of Central America" produced a steep-sided, 650-m-high stratovolcano over a 200-year period. Izalco was one of the most frequently active volcanoes in Central America, erupting basaltic-andesite pyroclastics and lava flows from both summit and flank vents, until activity ceased in 1966.
