Tsunamis are rare events with severe consequences. This generates a high demand on accurate simulation results for planning and risk assessment purposes because of the low availability of actual data from historic events. On the other hand, validation of simulation tools becomes very difficult with such a low amount of real-world data. Tsunami phenomena involve a large span of spatial and tempo...

Abstract One of the promising methods early warning a tsunami is obtaining data wave heights based on numerical solution inverse problem by using truncated singular value decomposition method as variant least-squares method. The considered within framework linear theory propagation. technique proposed allows one to avoid inevitable instability solution. It possible choose most informative direc...

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...

In the wake of the very large Indian Ocean tsunami on 26 December 2004, and several subsequent events in the Pacific Ocean, scientific and disaster mitigation studies have been initiated to better understand and observe tsunami propagation. This paper describes observations made on nearshore longperiod seismometers of a little known and, to our knowledge, recently discovered phenomenon associat...
