Details for: Lascar
Volcán Láscar (right) is the most active volcano of the northern Chilean Andes. A steam plume rises in 1986 from one of six overlapping summit craters capping the andesitic-to-dacitic stratovolcano, which is seen here from Toconao to the NW. Volcán Aguas Calientes (left center), an older, higher stratovolcano 5 km to the east, displays a well-developed summit crater and a probable Holocene lava flow near its summit. Frequent explosive eruptions have been recorded from Láscar since the mid-19th century. Photo by Paul King, MINSAL Corporation, 1986 (courtesy of Peter Francis, Open University).

Description: Láscar volcano in northern Chile is the most active of the northern Chilean Andes. Lascar is an andesitic-to-dacitic stratovolcano with 3 overlapping summit craters. Lascar has had a number of small to moderate explosive eruptions in historic times, as well as a few larger eruptions that caused ashfall hundreds of kilometers away.
