Ash simulations for Calbuco Volcano, April 22 2015

Here are some simulations with the Puff model. This is a 24 hour eruption, intial plume height of 13 km ASL, Mass eruption from height above event and Mastin et al. (2009) method and total mass of 2.65e11 kg. Outputs generated using Python scripting system.
