Fostered by and embedded in the general development of information and communications technology (ICT), the evolution of tsunami warning systems (TWS) shows a significant development from seismic-centred to multisensor system architectures using additional sensors (e.g. tide gauges and buoys) for the detection of tsunami waves in the ocean. Currently, the beginning implementation of regional ts...

[1] The speed of tsunami waves is typically calculated using the shallow-water approximation over a rigid-body Earth. Recent comparisons of tsunami arrival times from the 11 March 2011 tsunami suggest, however, that the standard formulation has errors around the 1% level, and it has been suggested that the elasticity of the Earth can explain the discrepancy. While previous work has indeed shown...

BACKGROUND The study investigated the impact of psychiatric disorders on Quality of Life (QOL) cross-sectionally and longitudinally in a group of Norwegian tourists severely exposed to the 2004 tsunami. METHODS Sixty-two adult Norwegian tsunami survivors were interviewed face to face 2 years post-tsunami (T1) and 58 were interviewed again by telephone 6 years post-tsunami (T2). The majority (...

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...

Landslides may pose perceptible tsunami hazards to areas commonly regarded as immune. A large number of historic and prehistoric slope failures have been reported covering a broad range of landslide volumes and resulting tsunamis. Landslide generated tsunamis were investigated in a two-dimensional physical laboratory model based on the generalized Froude similarity. The slide impact characteris...

Tsunamis are able to move large amounts of sediment during their inundation process. However, previous studies conducted to assess tsunami hazard have not considered tsunamiinduced sediment transport in their simulations, although it is possible that morphological adjustments during tsunami inundation increase the levels of hazard. In this paper, we present a model which is able to simulate sed...

Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to...

Eight years ago, some scientists computed for a 1.1-km diameter asteroid (1950 DA) a 0.0 to 0.3 per cent probability for colliding with Earth. Not long after this, a quasi-analytic model for wave propagation was used to describe the dynamics of the tsunami generated by the asteroid impact somewhere at 600 km east of the U.S. coast. Starting from the same initial conditions, our paper resumes th...

the huge earthquake in 11 march 2012 which followed by a destructive tsunami in japan was largest recorded earthquake in the history. japan is pioneer in disaster management, especially earthquakes. how this developed country faced this disaster, which had significant worldwide effects? the humanitarian behavior of the japanese people amazingly wondered the word's media, meanwhile the managemen...
