... ABSTRACT In the present paper, the liquefaction potential and the change in effective stress associated with the gap between the water pressure on the ground surface and the pore water pressure in the ground induced by tsunami inundation have been numerically studied. From the numerical...

... ABSTRACT A tsunami scenario determination methodology based on probabilistic tsunami hazard assessment is demonstrated. First, contributions of potential tsunami sources to the hazard curve, which is the relationship between tsunami height and the annual frequency of exceedance, are analyzed...

... ABSTRACT Targeting huge earthquakes and subsequent tsunamis, coastal structures require more improvements to enhance their durability and resilience. Thanks to recent studies, the accuracy of estimation of the wave forces by the overflowing tsunamis have been improved, in particular...
