Pieter-Ewald Share

Pieter-Ewald Share is an Assistant Professor of Geophysics at Oregon State University's College of Earth, Ocean, and Atmospheric Sciences. His research focuses on understanding active fault zones, particularly along the western North American plate boundary, using integrated geophysical methods including seismology, electromagnetism, and geodesy.

He combines multi-scale approaches to explore fault zone structures, fluid dynamics, and earthquake hazards. His work includes studies of the San Andreas and San Jacinto faults in California, leveraging innovative techniques like freight train seismic noise and magnetotelluric imaging. Share emphasizes a holistic approach to geohazard assessment, integrating data from diverse sources to improve societal resilience against earthquakes.

Before Oregon State, he conducted postdoctoral research at Scripps Institution of Oceanography and earned his PhD from the University of Southern California. His prior industry experience in deep South African mines provided unique insights into fault mechanics and subsurface imaging. Share actively mentors students and collaborates on projects like the Magnetotelluric Investigation of the Salton Trough (MIST) and the CRESCENT velocity model for Cascadia.

His research highlights the importance of multi-method geophysical synthesis, aiming to bridge gaps between academic disciplines for comprehensive tectonic understanding. Current efforts include imaging the Pacific Northwest's plate boundary and refining active fault monitoring through anthropogenic seismic sources.
