报告人：Prof. Jeff Freymueller
报告人简介：
Jeff Freymueller has been at the Geophysical Institute 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 Carolina in 1988 and 1991 respectively. His research combines geophysics and geodesy. He works both on understanding active earth processes, and on understanding and improving the tools we use to measure them.
报告题目：Megathrust Slip in Alaska in Space and Time
报告内容简介
The largest earthquakes occur in subduction zone environments, and most of them involve slip on the megathrust. But the slip behavior of the megathrust is highly variable along strike, downdip, and also in time. In this talk, I summarize more than 20 years of work on slip on the Alaska megathrust throughout the earthquake cycle, highlighting the variations in space and time, and the additional factors that need to be understood in order to estimate the slip behavior. While the root causes of along-strike changes in slip remain uncertain, in some cases the along-strike transitions can be correlated with inferred or measured changes in the properties of the plate interface.
