Propagation simulation
Tsunami numerical modeling is performed by using linear shalllow water theory on cartesian coordinates
with bathymetry/topography grid data of 30 arc-sec from GEBCO.
- Governing Equation : Linear Shallow Water Equations
- Numerical Scheme : Leap-frog Finite Difference Method
- Spatial Grid Size : 30 arc-sec
