Ash 3D is a three-dimensional simulation of volcanic-ash dispersion that uses time-varying wind fields and other meteorological properties to calculate where airborne ash is transported under current or historical atmospheric conditions

Hydrotherm is a computer code for three-dimensional simulation of multiphase groundwater flow and heat transport in the temperature range of 0 to 1200 degrees Celsius and the pressure range of 1 to 1000 MPa.

Laharz is a Geographical Information Systems tool for automated mapping of lahar inundation hazard zones.

Swarm is a Java application designed to display and analyze seismic waveforms in real-time. Swarm can connect to and read from a variety of different static and dynamics data sources, including Earthworm waveservers, IRIS DMCs, SEED and SAC files, and simple ASCII. Swarm has both time- and frequency-domain analysis tools, along with a simple but powerful mapping platfrom.
