主讲人介绍:

Prof. Shuhei Okubo was the director of Earthquake Research Institute at the University of Tokyo. He has been involved in the development and application of gravimetric methods for studying earthquake processes. He has presented comprehensive formulae on co-seismic gravity changes in various media including the simplest homogeneous elastic half-space and the most sophisticated stratified spherical viscoelastic earth. Through these theoretical works, the Guy Bomford Prize was awarded to him in 1991 by the International Association of Geodesy. He stepped further from the theoretical work to field measurement using a state-of-the-art FG5 absolute gravimeters. It was his group that found unambiguous co-seismic gravity change for the first time in the world (Tanaka et al., 2001) and very minute far-field gravity signal (Imanishi et al. 2004). He applied the theory on post-seismic gravity change to evaluation of secular gravity change around subduction plate boundaries.
