To improve stability of the computations, it is recommended to pre-process bathymetry map with depth_ssl (module included with the source code). +
Tsunami propagation from a source earthquake to a coastal site, land inundation. +
Time step is limited by Courant stability criteria (CFL < 1). Typical time step for open-ocean propagation: 15 s; near the coast: 0.5-5 s. Typical simulation time for geophysical tsunamis: few to 36 hours. +
