Research Abstract

We succeeded in extraction of global body-wave propagation by cross-correlating ambient noise wave field.Using autocorrelation analysis of ocean bottom seismometers, we detected temporal changes of s wave speeds and the azimuthal anisotropy in the shallow sedimentary layer. The changes can be explained by strong motion in the layer when the grate Tohoku earthquake in 2011. We also detected the temporal changes by cross correlation analysis of V-net data deployed by NIED.
