We investigate the role of a viscous compressible sedimentary layer underlying sea water on the formation, propagation and attenuation of hydro-acoustic waves. The analysis of low frequency pressure waves can be used for evaluation of stratified sediment structure. Two models based on depth-integration, for rigid and permeable sea bed are presented. The hydro-acoustic waves modeling, hereinafter presented can be used for tsunami prediction in large scale domains, overcoming computational difficulties of three-dimensional models and therefore enhance the promptness and accuracy of Tsunami Early Warning Systems (TEWS).
