Stephen J. Angster, Ph.D.


I am a field-based and analytical research geologist with the Earthquake Science Center who specializes in earthquake geology. My research aims to understand spatial and temporal distribution of earthquakes and active fault systems. My work is primary focused in the Pacific Northwest and informs seismic hazard models and future risk.

I have conducted geologic and geophysical based studies of complex fault systems in various tectonic settings throughout the U.S and internationally. I currently lead the Pacific Northwest paleoseismic studies task group for the Earthquake Science Center of the U.S. Geological Survey. My group focuses on assessing and characterizing Quaternary active faults within the upper continental plate of the Cascadia Subduction Zone.
