In the last years, large effort has been done to carry out multi-channel seismic reflection surveys (MCS) in SW Iberia to locate the active tectonic structures that could be related to the generation of the 1755 Lisbon earthquake and the tsunami. The outcome of these researches led to the identification of a large, compressive tectonic structure, named Marquês de Pombal thrust that, alone can a...

In a recent contribution, Fryer et al. (2004) have proposed to interpret many features of the 1946 Aleutian earthquake and tsunami as evidence for a major earthquake-triggered landslide. In particular, in support of their model, they claim that the T phase observed at Hawaiian Volcano Observatory (HVO) was generated at the time of the main shock, and dispute our earlier interpretation (Okal et ...

Statistical methods constitute a useful approach to understand and quantify the uncertainty that governs complex tsunami mechanisms. Numerical experiments may often have a high computational cost. This forms a limiting factor for performing uncertainty and sensitivity analyses, where numerous simulations are required. Statistical emulators, as surrogates of these simulators, can provide predict...

The 1867 Virgin Island Tsunami reached large magnitude on the coasts of the Caribbean Islands. A maximum tsunami height of 10 m was reported for two coastal locations (Deshaies and Sainte-Rose) in Guadeloupe. Modelling of the 1867 tsunami is performed in the framework of the nonlinear shallow-water theory. The directivity of the tsunami wave source in the Caribbean Sea according to the assumed ...

Tsunami observations have particular importance for resolving shallow offshore slip in finite-fault rupture model inversions for large subduction zone earthquakes. However, validations of amplitude linearity and choice of subfault discretization of tsunami Green’s functions are essential when inverting tsunami waveforms. We explore such validations using four tsunami recordings of the 25 Octobe...

Original scientific paper Tsunami is one of the serious natural disasters in the world, which produce huge horizontal thrust on costal buildings, resulting in a large number of houses collapsed instantaneously, causing serious casualties and economic losses. In this paper, based on support from the hydrodynamic software FLOW-3D, the method of Volume of Fluid (VOF) is utilized to capture free in...

High-frequency (HF) surface wave radars provide a unique capability to detect targets far beyond the conventional microwave radar coverage but also could contribute to the development and improvement of Tsunami Early Warning Systems. This paper describes the simulation of tsunami related signatures observed by HF radar at long ranges in case of a tsunami travelling towards the coast. A tsunami ...

OBJECTIVE To describe the distribution of mortality among internally displaced persons during two and a half months after the Indian Ocean tsunami, 2004. DESIGN Cross sectional household survey with retrospective cohort analysis of mortality. SETTING Camps for internally displaced persons due to the tsunami in an eastern coastal district of Sri Lanka. PARTICIPANTS 3533 people from 859 hou...

This paper describes the evolution through three generations of pneumatic Tsunami Simulators for physical model tests realistic tsunami. The method, originally developed tidal modeling in Fifties, has been modernized to generate extraordinarily long waves a controlled manner, with accurate reproduction recorded free-surface tsunami field data. how simulator designs were and they performed labor...
