Modeling a tsunami generated by the July 17, 2006 Earthquake , South of Java, Indonesia

Disaster Control Research Center (DCRC), Tohoku Univ.



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)
  • (Strike, Dip, Slip) = (270.0,7.0,67.0)
  • (L,W) = (45km,20km)
  • Dislocation = 2.3 m
  • Depth = 10 km

Model-3 (The fault paramters are based on CMT Solution of Harvard University)

  • Fault Origin = (9.596S,107.915E)
  • (Strike, Dip, Slip) = (289.0,10.0,95.0)
  • (L,W) = (84.8km,42.4km)
  • Dislocation = 3.71 m
  • Depth = 10 km

Model-4 (The fault paramters are based on CMT Solution of Harvard University)

  • (L,W) = (84.8km,42.4km)
  • Dislocation = 3.71 m
  • Depth = 10 km
