Ilopango volcano is a 8x11 km wide caldera at the eastern margin of San Salvador city, El Salvador. It is elongated to the east, has 150-500 m high walls and contains the scenic Lake Ilopango, one of El Salvador's largest.
The caldera is the result of at least 4 large plinian eruptions over the past few tens of thousands years. The lastest of these occurred in the 5th centruy AD. A historic eruption in 1879-80 formed Islas Quemadas ("burnt islands"), a group of islands in the center of the lake, corresponding to the summit of a mostly submerged post-caldera lava dome.
Ijen volcano photos: Ijen volcano in East Java is famous for its turquoise acid crater lake and the large sulfur deposits that are being mined by local workers. At night, the scene is illuminated by ghostly blue flames, as sulfur ignites.
