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.

Láscar is the most active volcano of the northern Chilean Andes. The andesitic-to-dacitic stratovolcano contains six overlapping summit craters. Prominent lava flows descend its NW flanks. An older, higher stratovolcano 5 km E, Volcán Aguas Calientes, displays a well-developed summit crater and a probable Holocene lava flow near its summit (de Silva and Francis, 1991). Láscar consists of two major edifices; activity began at the eastern volcano and then shifted to the western cone. The largest eruption took place about 26,500 years ago, and following the eruption of the Tumbres scoria flow about 9000 years ago, activity shifted back to the eastern edifice, where three overlapping craters were formed. Frequent small-to-moderate explosive eruptions have been recorded since the mid-19th century, along with periodic larger eruptions that produced ashfall hundreds of kilometers away. The largest historical eruption took place in 1993, producing pyroclastic flows to 8.5 km NW of the summit and ashfall in Buenos Aires.

Aguas Calientes Volcano or Cerro Aguas Calientes, also called Simba, is a cone-shaped stratovolcano located 5 kilometres (3 mi) east of the Lascar volcano and 14 kilometres (8.7 mi) north of Laguna Lejía, Chile. It is located within a 500 square kilometres (190 sq mi) area where the Cordón de Puntas Negras and the Cordón Chalviri volcanic chains intersect. The volcano is constructed from andesite and dacite containing hornblende and anhydrite; its pyroclastics are all older than Lascar. It has a diameter of about 7 kilometres (4.3 mi). Some xenoliths of calc-alkaline material are found in Aguas Calientes lavas, and magma mixing has generated lavas containing andesite inclusions in dacites. One eruption of Aguas Calientes postdates the first centre of Lascar and was originally linked to the Lascar Piedras Grandes eruption, before sampling on the deposits of this eruption indicated a relationship with the Lascar volcano itself. Effusion of lava ceased after the cone was built. One summit lava flow may be of Holocene age, but no evidence of historical activity is found.
