报告题目:Modeling Plate Boundary Deformation
报  告  人:Prof.  Jeffrey T. Freymueller 美国阿拉斯加大学 (University of Alaska )
邀  请  人:许才军  教授
     Prof Jeff Freymueller’s research interests include the kinematics and dynamics of active processes that shape the Earth. His active research projects include studies of tectonic deformation in plate boundary zones, earthquakes, postseismic deformation and the earthquake cycle, inflation and eruption of active volcanoes, glacial-isostatic adjustment and its effects on relative sea level, and variations in water, snow and ice via the deformation these load variations cause. He has made great contributions to the realm of geodesy and geophysics and has published more than 110 scientific papers that were issued in the journals of Nature, Science, Journal of Geophysical Research, Geophysical Research Letters and so on, and is a Fellow of the American Geophysical Union (AGU).
      He served as a member of the US National Committee for the International Union of Geodesy and Geophysics (IUGG) from 2003-2016, and was the chair of the committee and the USA representative to the IUGG Council from 2011-2016. The USNC/IUGG promotes the advancement of geodetic and geophysical sciences in the United States and throughout the world by participating in the activities of the IUGG. In addition, he was a past US National Representative to the International Association of Geodesy (IAG), a member of the Editorial Board of the Journal of Geodesy and a past President of the Geodesy Section of the AGU. He is also now Director of the EarthScope National Office.
      He has been at the Geophysical Institute of the University of Alaska Fairbanks since May 1995. He received a Bachelor of Science degree from the California Institute of Technology in 1985, and MS and PhD degrees from the University of South California in 1988 and 1991, respectively. Following his PhD, he worked as a Postdoctoral Researcher at Stanford University for three and a half years. Working in Alaska has been a tremendous opportunity, because so much happens right there; it is a signal-rich environment. But he has also maintained some work in other areas, including China, California, and South America. 

      Modeling plate boundary deformation is an important part of active tectonic studies. Block modeling approaches give us a means to separate the long-term tectonic motions from elastic effects associated with the earthquake cycle. This talk will highlight the basic concepts and methods of this important approach.
