Ringkasan geologi
San Vicente stratovolcano, also known as Chichontepec, is ~20 km SE of Lake Ilopango. The andesitic edifice with two summit peaks was constructed within the Pleistocene La Carbonera caldera, whose rim is visible only on its SW side. The N and S flanks are covered by lava flows from the central vent, but lava flows on the eastern side originated from a vent on the upper flank. Volcanism has continued into the Holocene, but the latest lava flows are covered by deposits from the major Tierra Blanca eruption from Ilopango around 450 CE. Reports of eruptions in 1643 CE and 1835 CE are false (Catalog of Active Volcanoes of the World; Sapper, 1917), but numerous hot springs and fumaroles are found on the N and W flanks.
Ringkasan Wikipedia
Ringkasan InggrisSan Vicente is a stratovolcano in central El Salvador. It is located next to the town of San Vicente and is the second highest volcano in El Salvador. In the indigenous language Nahuat, Chichontepec means the mountain of the two breasts, because its double summit resembles a woman's bosom. The volcano has two craters, one located in each summit, although not exactly at the top. A dense jungle covers both summits. Numerous hot springs and fumaroles are found on the northern and western flanks of the volcano. To the northeast, at 820 metres in a ravine of 180 metres longitude, there are fumaroles—fountains of clear and muddy water or small volcanoes of mud.
