Tsunami inundation modeling for western Sumatra.
A long section of the Sunda megathrust south of the great tsunamigenic earthquakes of 2004 and 2005 is well advanced in its seismic cycle and a plausible candidate for rupture in the next few decades. Our computations of tsunami propagation and inundation yield model flow depths and inundations consistent with sparse historical accounts for the last great earthquakes there, in 1797 and 1833. Nu...
متن کاملTsunami Inundation Mapping for Alaska Communities
Alaska has the greatest tsunami potential in the entire United States. Historic tsunamis generated by earthquakes on the Alaska-Aleutian subduction zone have resulted in widespread damage and loss of life along the Alaskan Pacific coast and other places located at exposed locations around the Pacific Ocean. Large seismic events occurring in the vicinity of the Alaska Peninsula, Aleutian Islands...
متن کاملInundation of sea water in Andaman and Nicobar Islands and parts of Tamil Nadu coast during 2004 Sumatra tsunami
Earthquakes of large magnitude generally above M 7.0, occurring in shallow depths of seabed fault zones, cause rapid and vertical displacement of sea water. This results in the generation of tsunamis. The tsunamis in turn generate a series of deep ocean waves that have larger wavelengths, greater amplitude, period and velocity compared to normal waves. These waves with tremendous energy propaga...

متن کاملA new numerical model for simulating the propagation of and inundation by tsunami waves A new numerical model for simulating the propagation of and inundation by tsunami waves
A new unstructured grid, finite volume ocean model is described, that is suitable for flooding and drying problems. Here we derive the finite volume analogue of the P 1 −P1 finite element, by interpreting the advective term in the continuity equation in a flux sense. A corresponding non-overlapping control volume is then selected for the momentum equation. The resulting model employs the median...
