About Dr. Scott Marshall

Dr. Scott Marshall holds a Ph.D. in geosciences from the University of Massachusetts at Amherst and teaches physical geology, geophysics, and data analysis courses at Appalachian State University. As a researcher, Marshall uses satellite data and mathematical models to better understand earthquake hazards. “The same network of satellites that most people use to find the best coffee in town can also be used to map out earthquakes and faults,” he says.

Marshall’s satellite imagery work has been funded repeatedly by the Southern California Earthquake Center (SCEC), allowing him to map where faults are and how fast they are moving in the Los Angeles and Ventura Basin areas. The data helps California determine which faults are active and which areas are at risk of earthquakes. His expertise is unique in the University of North Carolina system. Marshall notes that this is an exciting time to be an Earth scientist. “We can measure a millimeter of movement per year from  space – accurately,” he said. “The Earth sciences are currently undergoing a data revolution. We are able to make measurements that were simply not possible a decade ago.”
