Llaima

Stratovolkan · Chile · 3125 m

Llaima, one of Chile's largest and most active volcanoes, has a symmetrical profile when seen from the north. The massive, 3125-m-high, glacier-covered stratovolcano is constructed primarily of accumulated lava flows and has a volume of 400 cu km. Volcán Llaima contains two historically active craters, one at the summit and the other to the SE. More than 40 scoria cones dot the volcano's flanks. Frequent moderate explosive eruptions, a few of which were accompanied by lava flows, have been recorded since the 17th century.

Llaima, one of Chile's largest and most active volcanoes, contains two main historically active craters, one at the summit and the other, Pichillaima, to the SE. The massive, dominantly basaltic-to-andesitic, stratovolcano has a volume of 400 km3. A Holocene edifice built primarily of accumulated lava flows was constructed over an 8-km-wide caldera that formed about 13,200 years ago, following the eruption of the 24 km3 Curacautín Ignimbrite. More than 40 scoria cones dot the volcano's flanks. Following the end of an explosive stage about 7200 years ago, construction of the present edifice began, characterized by Strombolian, Hawaiian, and infrequent subplinian eruptions. Frequent moderate explosive eruptions with occasional lava flows have been recorded since the 17th century.
