Numerical modeling of tsunami

Numerical modeling of tsunami was performed by using TUNAMI code of DCRC. The model is based on the linear shallow water theory in the spherical co-ordinate system. Seismic deformation modeling is based on the theory of MANSINHA and SMYLIE (1971). The computational grid size is approximately 2 minutes of ETOPO2.

Earthquake mechanisms

Model-1 (The fault paramters are based on USGS Moment Tensor Solutions)

• Fault Origin = (9.4S,107.5E)
• (Strike, Dip, Slip) = (270.0,7.0,67.0)
• (L,W) = (45km,20km)
• Dislocation = 2.3 m
• Depth = 40 km

Model-2 (The fault paramters are based on USGS Moment Tensor Solutions)

• Fault Origin = (9.4S,107.5E)
