Please join us on Tuesday, October 2 at 3:00 p.m. as we welcome Dr. Yuning Fu, as assistant professor in geophysics from Bowling Green State University, for our latest installment of our colloquium series.
About the talk:
Changes in the shape of the Earth have been observed for several decades by advanced space-geodetic techniques, including the Global Positioning System (GPS). The surface of the Earth is displaced in elastic response to changes in surface mass loads. Spatial geodetic observational techniques, such as GPS, accurately measure the crustal loading deformation at millimeter-level accuracy. GPS-measured surface displacements, mainly in the vertical component, have been used to investigate global and local water mass load variations at sub-daily to inter-annual time scales. In this talk, I will introduce several scientific applications of GPS-measured accurate surface loading deformation, including estimations of water mass variations on the Earth surface, balancing hydrological water budgets, discovering the relationship between water storage change and seismicity rate variations with examples of California and Alaska, and probing Earth’s interior structure and so on.
