主讲人:Dr. Peiliang Xu

主讲人介绍:

Dr. Peiliang Xu studied at Wuhan University of Surveying & Mapping for 10 years and was conferred the first doctoral degree in geodesy in China in 1989. He then worked at Delft University of Technology, Stuttgart University and the University of Calgary as a postdoctoral researcher or an Alexander von Humbolt research Fellow before joining Kyoto University as an assistant professor in 1997. His research areas include space geodesy, satellite gravimetry, inverse problem theory, differential equations with unknown parameters, statistics and probability and applied optimization. His current research interest is mainly in mathematical seismology. He has published more than 80 scientific papers in a number of journals. His major scientific works include the qualitybased TSVD method and joint inversion theory, the signconstrained least squares method, integer estimation theory, measurement based perturbation and differential equation parameter estimation.

 

 

题目:Theoretical and Observational Advances of Gravimetry for Studying Earthquakes, Volcanic Eruptions and Tectonics

报告人:Prof. Shuhei Okubo

时间:722日,14:00~1530

地点:犀浦校区4520

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.
