Abstract

We use the 1965 Rat Islands earthquake to compare seismic wave inversion results for moment-release distributions to tsunami wave inversion results for slip distribution. Inversion using the two different datasets shows a high correlation between the areas of high moment release and areas of high slip. These areas of high slip correspond to the tectonic features of the western Aleutians, namely, the Rat, Buldir, and Near blocks. Less slip is observed between the blocks. The correlation indicates that far-field tsunami data is as useful as seismic data for studying moment distributions.
