Tsunami is gravity wave that propagates near the ocean surface. It is different form Tsunami and sea wave which we enjoy at the beach. Unlike common sea waves that evolve form the wind of sea, Most tsunamis spring from sudden shifts of the ocean floor. These sudden shifts can originate from earthquakes and undersea landslides.
This study will indicate the effect of that rupture complexity of shallow subduction zone earthquakes. Tsunami source parameters can ascribe the variability in local tsunami runup scaling like variation in the water depth in the source region, the combination of higher slip, etc. For a test region along the Pacific coast of central Mexico, the author use the model and 100 synthetic slip distribution patterns with identical seismic moment (
)to calculate a lot of peak nearshore tsunami amplitude. Analysis of the results can indicates there is substantially more variation in the local tsunami wave field derived from the inherent complexity subduction zone earthquakes than predicted by a simple elastic dislocation model.
