Abstract Sandy onshore deposits from tsunamis are difficult to distinguish storm deposits, which makes it assess coastal hazards the geological record. Here we analyse environmental DNA microbial communities preserved in known tsunami and storm-deposited sediments intercalating soils non-marine near Cuddalore, India, Phra Thong Island, Thailand. Both sites were impacted by 2004 Indian Ocean Tsu...

Oceanic underwater disturbances are associated with submarine landslides, volcano eruptions, or seismic activity occurring below near the ocean basin, which can produce tsunami, have a small amplitude in deep water very long wavelength, so they generally pass unnoticed offshore (Robke and Vott, 2017). These types of tsunami waves cause massive damage failures to coastal structures (Kato et al.,...

A well balanced numerical scheme based on stationary waves for shallow water flows with arbitrary topography has been introduced by Thanh et al. [18]. The scheme was constructed so that it maintains equilibrium states and tests indicate that it is stable and fast. Applying the well-balanced scheme for the one-dimensional shallow water equations, we study the early shock waves propagation toward...

Indian Ocean is known as a source of moisture for southeast of Iran due to summer precipitation. In this study, in order to investigate the role of SST of Indian Ocean, and the convergence and divergence fields in the precipitation of southeast of Iran, precipitation data of five synoptic stations were used during 2000-2010, including Iranshahr, Khash, ChahBahar, Zabul, and Saravan. To investig...

A series of experiments has been carried out at the Tsunami Wave Basin (TWB) at Oregon State University (OSU) to determine the effect of tsunami bores on coastal and nearshore structures, especially buildings and bridges. The TWB is equipped with a piston-type wavemaker capable of generating clean solitary waves. The facility was used to model tsunami bores breaking over coastal reefs and their...

Secondary magnetic fields are induced by the flow of electrically conducting seawater through the Earth's primary magnetic field ('ocean dynamo effect'), and hence it has long been speculated that tsunami flows should produce measurable magnetic field perturbations, although the signal-to-noise ratio would be small because of the influence of the solar magnetic fields. Here, we report on the de...
