Earth is an active planet, generating various indigenous sources and, at the same time, responding to them as a medium.  As a geophysicist, Prof. Park's ultimate goal is to understand the Earth’s dynamics by examining the source processes and Earth’s structure.  Her research areas cover a wide range of topics in seismology, including earthquake rupture, deep earthquakes, near-surface seismic structure, mantle transition zone, rheological structure from asthenosphere to upper mantle, and ground motion prediction.  Among these disparate subjects, there is a common theme: the development of novel approaches to expand our ability to study the Earth’s internal processes.
