Abstract：We use two methodsto get the ocean floor deformation data caused by the 2011 Tohoku-Oki earthquake. Then the gravity effects due to the redistribution of ocean floor mass can be calculated through Fourier transformation and Fourier inverse transformation. These gravity effects are analyzed and compared to the gravity data observed by GRACE satellite. The results show that these gravity effects are notable, and should be of concern during extracting coseismic gravity changes.
