Abstract
Great earthquakes along subduction-zone plate boundaries, like the 2011 magnitude 9.0 Tohoku-Oki, Japan, event, deform the seafloor to generate massive tsunamis. Tsunami wave heights near shore are greatest when excitation occurs far o shore near the trench, where water depths are greatest and fault slip is shallow. The Tohoku event, featuring over 30 m of slip near the trench exemplifi es this hazard. Unfortunately the rupture process that far o ffshore is poorly constrained with land-based geodetic and even most seafloor deformation measurements, and seismic inferences of shallow slip are often nonunique. Here we demonstrate, through dynamic rupture simulations of the Tohoku event, that long-period guided waves in the ocean (specifi cally, leaking oceanic P-wave modes known as PL waves) can resolve the shallow rupture process and tsunami excitation near the trench. With predicted pressure changes of 0.1{1 MPa along most of the seafloor landward of the trench, and periods of several seconds, these PL waves should be observable with ocean-bottom pressure sensors and/or seismometers. With cabled sensor networks like those being deployed o shore Japan and in other subduction zones, these waves could be used to rapidly quantify shallow slip and near-trench sea floor uplift and improve local tsunami early warning systems.

    Rupture to the Trench: dynamic rupture simulations of the 11 March 2011 Tohoku Earthquake 

    Kozdon, Jeremy E; Dunham, Eric M. (2013-05);
    There is strong evidence that the 11 March 2011 Tohoku earthquake rupture reached the seafloor. This is surprising because the shallow portion of the plate interface in subduction is thought to be frictionally stable, ...

    APPLICATION OF ACOUSTIC NOISE INTERFEROMETRY TO REMOTE SENSING OF A COASTAL OCEAN 

    Tan, Tsu Wei (Monterey, CA; Naval Postgraduate School, 2019-12);
    As noted by Tan, Godin, Brown, and Zabotin in 2019, interferometry of ambient and shipping noise in the ocean provides a way to estimate physical parameters of the seafloor and the water column in a surreptitious and ...
