The top of Llaima consists of two summits; the lower of the two, Pichillaima, is about 2,920 m (9,580 ft) high and is significantly less prominent than the higher northern summit. [2] The average elevation of the terrain around Llaima is about 740 m asl. [2] The volcano summit is located 10 km West South West of Conguillío Lake.
Llaima volcano was formed during the Quaternary, on lava and granites located throughout the faults system of longitudinal North – South. It is composed of mixed volcano and shield, with a boiler covered with forty accidental dreg cones and presents a secondary chimney to 9.514,44 feet above the sea level. The slope of this volcano is moderate.
The country's National Geology and Mining Service lists 90 active volcanoes. [2] The volcanoes of the Andes originate from the subduction of the Nazca Plate under the South American Plate, while the volcanoes of Chile's Pacific islands formed from magma coming from three distinct hotspots, Easter, Juan Fernández and San Felix hotspots. The ...
Llaima volcano in eruption. The geology of Chile is a characterized by processes linked to subduction, such as volcanism, earthquakes, and orogeny.The building blocks of Chile's geology were assembled during the Paleozoic Era when Chile was the southwestern margin of the supercontinent Gondwana.

View of Conguillío Lake and Llaima Volcano, both part of Kütralkura Geopark. Kütralkura (Spanish: Geoparque Kütralkura, from Mapudungun kütral, fire, and kura, stone, meaning "firestone" [1]) is a geopark in southern Chile's Araucanía Region. The geopark has an area of 8100 km 2 and lies mostly in the Andes.
The process of glacier retreat is probably accelerated by ash being deposited on the glacier through eruptions at the neighbouring volcano Puyehue-Cordón Caulle; activity at the other volcanoes Llaima and Villarrica may have the same effect. [25] In 2011, the volume of the glacier was 4.5 ± 0.5 km 3 (1.08 ± 0.12 cu mi). [8]
