Robert Skoumal


I am a research geophysicist at the Earthquake Science Center in Moffett Field, California. My research focuses on improving our ability to characterize both natural and induced (“anthropogenic”) earthquakes. I am particularly interested in developing new methods to identify small magnitude earthquakes over regional distances, creating methods to distinguish between natural/induced seismicity, investigating geologic/industrial parameters that influence the likelihood of inducing earthquakes, and using “Large-N” datasets (e.g., nodal arrays, distributed acoustic sensing) to better characterize earthquakes.
