     abstract = "{Large earthquakes at subduction zones usually generate tsunamis and
        coseismic gravity changes. These two independent oceanic and
        geodetic signatures of earthquakes can be observed individually
        by modern geophysical observational networks. The Gravity
        Recovery and Climate Experiment twin satellites can detect
        gravity changes induced by large earthquakes, while altimetry
        satellites and Deep-Ocean Assessment and Reporting of Tsunamis
        buoys can observe resultant tsunamis. In this study, we
        introduce a method to connect the oceanic tsunami measurements
        with the geodetic gravity observations, and apply it to the 2004
        Sumatra Mw 9.2 earthquake, the 2010 Maule Mw 8.8 earthquake and
        the 2011 Tohoku Mw 9.0 earthquake. Our results indicate
        consistent agreement between these two independent measurements.
        Since seafloor displacement is still the largest puzzle in
        assessing tsunami hazards and its formation mechanism, our study
        demonstrates a new approach to utilizing these two kinds of
        measurements for better understanding of large earthquakes and
        tsunamis.}",
