Runup from Impact Tsunami
Tsunami generated by the impacts of asteroids or comets are widely recognized as a potential hazard (Hills et al 1994, in Hazards Due to Comets and Asteroids ed. T. Gehrels, Chapman and Morrison 1994 Nature 367, 33, Ward and Asphaug 2000, Icarus, 145, 64, Atkinson et al. 2000, Report of the UK Task Force on potentially hazardous NEOs, Chesley and Ward 2003, J. Geophys. Res., submitted). The glo...
متن کاملPower-law Scaling and Probabilistic Forecasting of Tsunami Runup Heights
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...
متن کاملDynamics of tsunami waves
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...
متن کاملInflation from Tsunami-waves
We investigate inflation driven by the evolution of highly excited quantum states within the framework of out of equilibrium field dynamics. These states are characterized by a nonperturbatively large number of quanta in a band of momenta but with vanishing expectation value of the scalar field. They represent the situation in which initially a non-perturbatively large energy density is localiz...
متن کاملNumerical methods for a reliable prediction of water wave phenomena : uncertainty quantification for tsunami runup
Aim of this study is to present robust numerical methods for shallow water equations permitting to correctly predict long water-wave phenomena. A semi-intrusive and polynomialchaos based method are coupled with a residual based distribution scheme by considering several sources of uncertainties in the simulation of a long wave runup on a conical island. Stochastic results are assessed by compar...
