Tsunami Shallow Water Model
The tsunami shallow water model is a numerical method based on shallow water equations that simulates tsunami wave propagation from earthquake source regions to coastal areas. Developed by Kenji Satake and colleagues in the 1990s, this approach provides rapid estimates of tsunami arrival times, wave amplitudes, and inundation extents for operational early warning systems. The model forms the computational backbone of tsunami warning centers worldwide.
