Eruption Style

Calbuco is a very explosive volcano because of its high viscosity lava. The main type of lava Calbuco releases is basaltic lava. Mt. Calbuco has been known to have had pyroclastic flows in the past. Also it is common to have Lahars (mud flows) and debris erupting out of Calbuco.

Enviromental Dangers/Benefits

Mt. Calbuco has had many eruptions in its history. Every time Calbuco erupts many harmful gasses are being released into our atmosphere. These gasses are then trapped and add to global warming dangers. In the 1893-1894 eruption many homes and buildings were damaged due to the debris and ash fall. Also many of the crops that were growing were destroyed from all of the ash fall.
