The problems of tsunami generation are treated by standard integral-transform and modified stationary-phase methods to yield asymptotic approximations to the surface disturbances. The effects of asymmetry are considered in a one-dimensional ocean. Series representations are used to produce sets of normal-mode oscillations in a two-dimensional ocean ...

The Makran subduction located at the northwest of the Indian ocean, at the Oman Sea mouth has been and is the source of massive tsunamis that threatens the coasts of Iran, Pakistan, India and Oman.

The Role of Frontal Thrusts in Tsunami Earthquake Generation
Bulletin of The Seismological Society of America (BSSA), 2021The frontal sections of subduction zones are the source of a poorly understood hazard: “tsunami earthquakes,” which generate larger-than-expected tsunamis given their seismic shaking.

Temporal and Topographic Source Effects on Tsunami Generation
Journal of Geophysical Research: Oceans, 2019We present a systematic study of the influence on tsunami waves generated by the uplift of a rectangular plug, of the rise time of the deformation, and of its topographic details (e.g., the presence of a sill).

Using a dynamic earthquake simulator to explore tsunami earthquake generation
Geophysical Journal International, 2021Observations of historical tsunami earthquakes reveal that ruptures of these earthquakes propagate slowly at shallow depth with longer duration, depletion in high-frequency radiation, and larger discrepancy of Mw-Ms than ordinary megathrust earthquakes.

Abstract An analytical and experimental study of the baroclinic waves generated by a monopole dislocation of the sea floor is presented. Analytical results are based on a two-dimensional and linearized description of motion using a two-layer approximation for density variation; experiments utilize a stratification with finite (nonzero) pycnocline ...

The most common cause of tsunami is seismic activity. Over the past two millennia, earthquakes have produced 83.0 % of all tsunami in the Pacific Ocean. Displacement of the Earth’s crust by several meters during underwater earthquakes may cover tens of thousands of square kilometers and impart tremendous potential energy to the overlying water.

Study on generation mechanism of vertical force peak values on T-girder attacked by tsunami bore
, 2020The generation mechanism and characteristics of peak values of tsunami bore vertical force are investigated comprehensively and thoroughly. A scaled down two-dimensional T-girder model, whose surface is divided into a series of panels, is tested in the ...

Tsunami generation in compressible ocean
Physics and Chemistry of the Earth, Part B: Hydrology, Oceans and Atmosphere, 1999Abstract Most of the tsunami modelling studies have been carried out within the framework of incompressible fluid theory. Estimations we made show that this approach quite appropriately describes the stages of tsunami propagation and run-up, whereas incompressible fluid theory fails to describe the process of tsunami generation properly.
