The snowy cone of Llaima volcano
|Elevation||3,125 m (10,253 ft) |
|Prominence||1,819 m (5,968 ft) |
Region high point|
|Location||Melipeuco and Vilcún, Cautín Province, La Araucanía Region, Chile|
|Last eruption||2008 to 2009|
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.
The average elevation of the terrain around Llaima is about 740 m asl.
The volcano, along with Sierra Nevada, surrounds the Conguillío Lake. Its slopes are drained by the rivers Captrén, Quepe and Trufultruful. The former ones are tributaries of Cautín River and the latter is affluent of Allipén River.
Llaima is one of Chile's most active volcanoes and has frequent but moderate eruptions. Llaima’s activity has been documented since the 17th century, and consists of several separate episodes of moderate explosive eruptions with occasional lava flows. The last major eruption occurred in 1994.
An eruption on January 1, 2008 forced the evacuation of hundreds of people from nearby villages. A column of smoke approximately 3000 m high was observed. An amateur caught the early eruption phase on video. The volcanic ash expelled by Llaima travelled east over the Andes into Argentina. Ash fall was recorded in the area of Zapala, Neuquén Province, and forced the cancellation of flights to and from Presidente Perón Airport near the city of Neuquén. On July 2, 2008, another eruption resulted in evacuation of 40 people from a 15 km exclusion zone.
An eruption occurred on April 5, 2009, with pyroclastic flows, ash and lava seen on the slopes.
The ski center Las Araucarias lies on the volcano's western slopes.
