Mount Maipo

Mount Maipo, among the most active border stratovolcanoes in the south-central Andes, sits mightily on the Chile-Argentina borders.  This volcano partially fills the Pleistocene Diamante caldera, and is elevated nearly 1900 meters above the caldera’s floor as a result of strombonian-vulcanian activity.  Its aesthetic appeal comes mostly from the luscious layer of ash and glacial deposits which neatly blanket Maipo’s surface.  This ash comes from the last significant eruption which occurred in 1826, with the explosive emission of lava and other volcanic material.  Other than that, Maipo’s eruption level has diminished to mild explosions here and there, most of which barely reach a VEI of 2.  The latest dish on activity  on Maipo is the claim of of a landslide or avalanche in 2004 just to the east of its peak, as a result of the season’s increasing temperature.  Besides this and the last recorded eruption, which occurred in 1912, Maipo’s active calderas merely continue to rest peacefully.
