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....

A shore-based High-Frequency (HF) WERA radar was recently installed by Ocean Networks Canada (ONC) near Tofino, British Columbia (Canada), to mitigate the elevated tsunami hazard along the shores of Vancouver Island, from both farand near-field seismic sources and, in particular, from the Cascadia Subduction Zone (CSZ). With this HF radar, ocean currents can be measured up to a 70-85 km range, ...

In this article we wish to evaluate efficiency of use of Dnieper cascade hydropower plants on the basis of common approaches to environmental management. We evaluate the efficiency of use the flooded areas of the hydropower station in agriculture. Assessment of the man-made risks includes evaluation of static (regular maintenance of dams) and stochastic (probability of artificial tsunami) compo...

We investigate the generation, propagation, and probabilistic hazard of tsunami spawned by oceanic asteroid impacts. The process first links the depth and diameter of parabolic impact cavities to asteroid density, radius, and impact velocity by means of elementary energy arguments and crater scaling rules. Then, linear tsunami theory illustrates how these transient cavities evolve into vertical...

in western coast of gujarat destructive tsunamis have been generated from large earthquakes along the makran coast, chagos ridge and kutch region in the past. although the historical record is incomplete, it is believed that such tsunamis were destructive on the coasts of india, pakistan, iran, oman and sri lanka and possibly had significant effects on islands. the most significant tsunamigenic...

The long-standing uncertainty about the importance of asteroid-generated tsunami was addressed at a workshop in August 2016, co-sponsored by NASA and NOAA. Experts from NASA (Ames, JPL), NOAA, DoE (LLNL, SNL, LANL), DHS, FEMA, and academia addressed the hazard of tsunami created by asteroid impacts, focusing primarily on impacting NEAs with diameter <250m. Participants jointly identified key is...

In the vast literature on tsunami research, few articles have been devoted to energy issues. A theoretical investigation on the energy of waves generated by bottom motion is performed here. We start with the full incompressible Euler equations in the presence of a free surface and derive both dispersive and non-dispersive shallowwater equations with an energy equation. It is shown that dispersi...

The life of a tsunami is usually divided into three phases: the generation (tsunami source), the propagation and the inundation. Each phase is complex and often described separately. A brief description of each phase is given. Model problems are identified. Their formulation is given. While some of these problems can be solved analytically, most require numerical techniques. The inundation phas...
