... Abstract Several formulas have already been proposed to predict the impact force of flotsam caused by tsunamis. All of these equations require the impact velocity of the flotsam to calculate the impact force, and many studies have been conducted on the drifting velocity of the flotsam. Although...

... Abstract When a tsunami attacks a coastal area, vessels moored at the wharf suffer serious damage. In fact, more than 20,000 vessels have been damaged, such as landing on a wharf, drifting, or colliding due to the tsunami caused by the Tohoku earthquake in 2011. Tsunamis are significant...

... Abstract A tsunami earthquake is defined as an earthquake which induces abnormally strong tsunami waves compared with its seismic magnitude (Kanamori 1972; Kanamori and Anderson 1975; Tanioka and Seno 2001). We investigate the possibility that the surface waves (Rayleigh, Love, and tsunami...

... Abstract We first propose and examine a method for digitizing analog data of submarine topography by focusing on the seafloor survey records available in the literature to facilitate a detailed analysis of submarine landslides and landslide-induced tsunamis. Second, we apply this digitization...

... Abstract In order to simulate drifting and run-up ice floes driven by tsunamis, we developed a quasi-3D Discrete Element Method (DEM) in which phenomena unique to granular solids, such as the arch action, jam and pile up of such solids, can be simulated with a small computation load...

... in the tsunami wave runup and interaction of the propagating solitary waves with the idealized coastal beaches. To better understand the physical processes of the tsunami wave runup at surf zone, a parametric study concerning N-wave runup is carried out. For all cases investigated, the qualitative features...

... 01 11 2011 Our objective is to investigate the effect of combined swell–tsunami interaction on the nature of the tsunami — in particular the surface elevation, the runup speed and the near-bottom velocities. Laboratory testing in the Tsunami Wave Basin at Oregon State University has...
