Tsunami warnings using ocean circulation models

Song et al., AGU

This resource is an abstract. This study uses numerical models that take advantage of digital seismometry and satellite radar altimetry to shed light on tsunami source and formation mechanisms. The authors used data from the 26 December 2004 tsunami to generate a 3-D ocean circulation model that they compared it to actual wave propagation recorded by satellites. It was found that the model consistently matches the observed phenomenon. The authors suggest that ocean-general-circulation-models coupled with fresh earthquake data can provide earlier warning to coastal communities at risk.
