Numerical models
There are various approaches for modeling the tsunami source: e.g. rockslides, landslides, earthquakes, and asteroid impacts.

The following numerical models have been investigated and used:
- GloBouss, the dispersive tsunami model for propagation, was developed at the University of Oslo (UiO), NGI, and ICG. The model may be initiated by slides and earthquakes. Documentation for this model can be found here.
- Inundation modeling using NOAA's ComMIT/MOST.
- For the combination of dispersive tsunami propagation and inundation modeling, we are using the output from GloBouss as input to ComMIT/MOST.
