TephraProb

TephraProb is a toolbox of Matlab functions designed to produce scenario-based probabilistic hazard assessments for ground tephra accumulation using on the Tephra2 model. The toolbox includes series of GUIs that allow to:

• Retrieve and analyse wind conditions from the NOAA Reanalysis and the ECMWF ERA-Interim datasets;
• Create calculation grids in UTM;
• Retrieve and analyse eruption datasets from the Global Volcanism Program database;
• Create distributions of eruption source parameters based on a wide range of probabilistic eruption scenarios;
• Run Tephra2 using the generated input scenarios;
• Compile exceedence probability maps, probabilistic isomass maps and hazard curves.

Usage

In Matlab, navigate to the root of TephraProb, type

>> tephraProb

and press enter.
