Abstract

T WAVES propagate in the so-called SOFAR CHANNEL of minimum sound velocity centered on 1200 meters depth acting as a waveguide for ACOUSTIC ENERGY in the world’s oceans. They can be excited by sources in the solid earth such as earthquakes through conversion of seismic energy into acoustic waves at the solid- liquid interfaces. As a particular form of seismic waves emanating from an earthquake, T WAVES can provide insight into seismic sources in the ocean environment. Considering the application of this phase to detect small earthquakes in marine basins and ability to yield information on source rupture and detect submarines by using the small explosion and analysis of this phase and also using of this phase in modeling of Tsunami earthquake study on T WAVES is an essential. Study on T WAVES shows p and s or surface waves conversions occurs offshore. So it can be travel hundreds of kilometers away from the coastline. Indeed, when the seismic waves resulting from receiver-side conversion is of sufficient amplitude, it can be felt by the population close to shore even though the source of the ACOUSTIC ENERGY maybe thousands of kilometers away. For instance, large earthquake in Sumatra in 2004 on Maldives was occurred was this group. Remarking that there is no study of T WAVES in Iran, investigation of this phase can open up new opportunities for the investigation of acoustic sources, including earthquakes, in the ocean environment.
