Project Grant 2348119

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $302,361 to Purdue University to conduct collaborative research on the driving forces and active faults in the Eastern Eurasian and Western North American Arctic regions. The researchers will analyze GPS data to map surface movements, develop computer models to estimate fault slip rates and understand the key forces causing earthquakes in this area, which is important for assessing earthquake risk. This work will involve integrating GPS and seafloor spreading data to create a synoptic regional velocity field, as well as performing 3D geodynamic simulations to examine how factors like gravity, mantle flow, and plate tectonics contribute to surface deformation in Alaska and the broader Arctic region. The award period runs from August 1, 2024 to July 31, 2027.
