Introduction
A magnitude of 7.3 earthquake occurred 37km ESE of Namie, Japan on November 22, 2016 at 20:59:49.010 UTC (USGS). We have simulated the tsunami generated using a focal mechanism version 2 according to USGS.

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
