The OpenQuake volcano calculator can be used for the estimation of damage distribution statistics or individual asset and portfolio loss statistics for a portfolio of buildings starting from hazard footprints.
The following four hazard perils can be considered:
Ash fall
Lahar
Lava flow
Pyroclastic density currents
For Ash fall, the ash load in kPa is considered as the hazard intensity. The other perils are assumed to be a binary phenomena.
