Tsunami is one of the most severe natural disasters faced by regions around the rim of oceans, usually generated by submarine earthquakes (usually with magnitude larger than 7.0), volcano eruptions and large landslides. Submarine earthquakes are the most common tsunami sources. As we know, the prediction of an earthquake is still not satisfactory with today's technologies, in fact, for most ear...

Our objective is to produce a mechanically realistic model for the 1975 Kalapana event that explains the overall deformation and geological evolution of the south flank of Kilauea, and reproduces most known earthquake and tsunami observations. To do this, we present a new structural interpretation of geological data from Kilauea, along with modeling of the tsunami using recent seismic analyses....

Recent tsunami events have stimulated research activity into tsunami fragility functions which have been largely based on empirical data. However, empirical fragility functions are biased because the influence of earthquake and tsunami damage are difficult to separate. We develop a new theoretical framework to assess the structural performance of a building due to tsunami inundation by drawing ...

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...

A power-law scaling relationship describes tsunami runup heights at ten locations in Japan. Knowledge of the scaling law for tsunamis can be the basis for probabilistic forecasting of the size and number of future events and for estimating probabilities of extremely large events. Using tsunami runup data archived by the U.S. National Geophysical Data Center, we study ten locations where the tsu...

Massive tsunamis induce catastrophic disturbance in marine ecosystems, yet they can provide unique opportunities to observe the process of regeneration. Here, we report the recovery of fauna after the 2011 tsunami in northeast Japan based on underwater visual censuses performed every two months over five years. Both total fish abundance and species richness increased from the first to the secon...

The tsunami that struck South-east Asia on 26 December 2004 left more than 500,000 people in Aceh, Indonesia, homeless and displaced to temporary barracks and other communities. This study examines the associations between prolonged habitation in barracks and the nature of fears reported by school-age children and adolescents. In mid-2007, 30 months after the tsunami, the authors interviewed 15...

introduction tsunami is a series of water waves caused by the displacement of a large amount of water which is generated by underwater earthquake, volcano, landslide or other disturbances below water. the makran subduction zone (msz) is one of the regions that have potential to generate tsunami which also has been occurred in 1985 and is capable of another one. in msz, the coasts of chabahar ba...

The 1883 Krakatau volcanic eruption has generated a destructive tsunami higher than 40 m on the Indonesian coast where more than 36 000 lives were lost. Sea level oscillations related with this event have been reported on significant distances from the source in the Indian, Atlantic and Pacific Oceans. Evidence of many manifestations of the Krakatau tsunami was a subject of the intense discussi...

The risk of large, devastating tsunamis in the South China Sea and its surrounding coastal region is commonly underestimated or unrecognized due to the difficulty of differentiating tsunami from storm deposits. As a consequence, few convincing records have documented tsunami deposits in this region. Here we report preliminary evidence from Xisha Islands in the South China Sea for a large tsunam...
