Some Aspects of Energy Balance and Tsunami Generation by Earthquakes and Landslides
Tsunamis are generated by displacement or motion of large volumes of water. While there are several documented cases of tsunami generation by volcanic eruptions and landslides, most observed tsunamis are attributed to earthquakes. Kinematic models of tsunami generation by earthquakes — where specified fault size and slip determine seafloor and sea-surface vertical motion — quantitatively explai...
متن کاملA New Method for Acquisition of High-Resolution Seabed Topography by Matching Seabed Classification Images
The multibeam echo sounders (MBES) can acquire accurate positional but low-resolution seabed terrain and images, whereas side scan sonars (SSS) can only acquire inaccurate positional but high-resolution seabed images. In this study, a new method for superimposing corrected-positional SSS images on multibeam bathymetric terrain is proposed to obtain high-resolution and accurate-positional seabed...
متن کاملTsunami excitation by inland/coastal earthquakes: the Green function approach
In the framework of the linear theory, the representation theorem is derived for an incompressible liquid layer with a boundary of arbitrary shape and in a homogeneous gravity field. In addition, the asymptotic representation for the Green function, in a layer of constant thickness is obtained. The validity of the approach for the calculation of the tsunami wavefield based on the Green function...
متن کاملObservation of Local and Distant Earthquakes and Tsunami Warning System
In Japan, Japan Meteorological Agency, JMA, has the official responsibility for the public for tsunami forecasts and issuance of tsunami information. For the tsunami forecast the first step is precise and prompt estimation of the location and magnitude of the earthquake because generation of tsunami is strongly controlled by the focal depth and the magnitude of the earthquake. In case that the ...
متن کاملTsunami Generation by Submarine Mass Failure
Numerical experiments are conducted for two-dimensional model problems of tsunami generation by underwater slides and slumps. These problems consist of a semi-ellipse, translating down an incline with a prescribed center of mass motion. For each problem, this motion is derived as a function of geometric and material parameters, and we calculate corresponding characteristic tsunami amplitudes. L...
