Michinmahuida

Wednesday, June 30, 2010

Michinmahuida is a glaciated stratovolcano located in Los Lagos Region of Chile. It situated about 15 km east of Chaiten volcano, and was extensively covered in ash during the 2008 eruption of Chaiten. The Michinmahuida lies above the regional Liquine-Ofqui Fault zone, and the ice-covered massif towers over the south portion of Pumalín Park. The Michinmahuida volcano is also known as Michinmávida or Michimahuida.

Two major explosive eruptions of the Michimahuida during the Holocene produced tephra deposits extending to the east. An eruption from Minchinmávida was reported in 1742. Darwin observed the volcano in activity in 1834 on his renowned voyage that took him to the Galápagos Islands. The latest known eruption of basaltic-to-andesitic Minchinmávida, from February to March 1835, produced a lava flow from a flank crater and lahars that reached the coast at Punta Chana.
