Llaima


Llaima Volcano is one of the largest and most active volcanoes in Chile. It is situated 82 km northeast of Temuco and 663 km southeast of Santiago, within the borders of Conguillio National Park.

Geography

The top of Llaima consists of two summits; the lower of the two, Pichillaima, is about 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 Conguillio Lake. Its slopes are drained by the rivers Captren, Quepe and Trufultruful. The former ones are tributaries of Cautin River and the latter is affluent of Allipen River.

Eruptions

Llaima is one of Chile's most active volcanoes and has frequent but moderate eruptions. Llaimas 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, Neuquen Province, and forced the cancellation of flights to and from Presidente Peron Airport near the city of Neuquen. 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.

Recreation

The ski center Las Araucarias lies on the volcano's western slopes.
