  • 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
