ACOUSTIC-GRAVITY WAVES, THEORY & APPLICATIONS

Lead Research Organisation: Cardiff University
Department Name: Sch of Mathematics

Abstract

Acoustic-gravity waves (AGWs) are compression-type waves propagating with amplitudes governed by the restoring force of gravity. They are generated, by wind-wave interactions, surface wave interactions, and movements of the tectonic lithosphere plates. They travel at the speed of sound in water carrying information on their source. Employing AWGs we aim to improve current sea-state warning systems with a particular focus on early detection of tsunami.

Description An inverse semi-analytical model has been developed, based on the analytical solution, published by Mei & Kadri (2018). This model allows to retrieve the properties of an efective slender earthquake from the theoretical pressure signal (hydroacoustic signal) that it induces in the far field. This model can be applied to real data under certain scenarios. It is conceived as an early stage of a potential early tsunami warning system, however it can be also applied to other cases such as fallin objects in the ocean.
Exploitation Route Me and my supervisor (Usama Kadri), we are writting an article with the findings, in order to be published. This will allow other researchers to replicate our work and apply it to real case scenarios.
