[1] Five shallow pressure gauges located in straits in the southern Indonesian islands were used to evaluate tsunami signals triggered by the earthquakes off the northwest coast of Sumatra in December 2004 and the south coast of Java in July 2006. Tsunami waves reached the pressure gauges around 5 to 6 hours after the 2004 earthquake; the largest waves arrived 10 to 23 hours later, with amplitu...

Results from different tsunami forecasting and hazard assessment models are compared with observed tsunami wave heights from the 26 December 2004 Indian Ocean tsunami. Forecast models are based on initial earthquake information and are used to estimate tsunami wave heights during propagation. An empirical forecast relationship based only on seismic moment provides a close estimate to the observ...

-Heterogeneous fault motion of the 1993 Hokkaido Nansei-Oki earthquake is studied by using seismic, geodetic and tsunami data, and the tsunami generation from the fault model is examined. Seismological analyses indicate that the focal mechanism of the first 10 s, when about a third of the total moment was released, is different from the overall focal mechanism. A joint inversion of geodetic dat...

Tsunami propagation is analyzed for the Ligurian Sea with particular attention on the French coasts of the Mediterranean. Historical data of tsunami manifestation on the French coast are analyzed for the period 2000 B.C.– 1991 A.D. Numerical simulations of potential and historical tsunamis in the Ligurian Sea are done in the context of the nonlinear shallow water theory. Tsunami wave heights as...

This paper proposes a robust method for modeling shallow-water flows and near shore tsunami propagation, applicable for both simple and complex geometries with uneven beds. The novel aspect of the model includes the introduction of a new method for slope source terms treatment to preserve quiescent equilibrium over uneven topographies, applicable to both structured and unstructured mesh systems...

Abstract. Tsunamis rarely occur in a specific area, and their occurrence is highly uncertain. Suddenly generated from sources deep water, they occasionally undergo tremendous amplification shallow water to devastate low-lying coastal areas. Despite the advancement of computational power simulation algorithms, there need for novel rigorous approaches efficiently predict tsunamis during different...
