Robert McPherson

Seismology, seismotectonics

  • M.S., Environmental Geology, Humboldt State University, Arcata, 1989
  • A.B., Geology, Humboldt State University, Arcata, 1973
Professional Experience:
  • Joined HSU 1989
Courses Taught:

My research interests for the past 30 years have been North Coast Seismicity and the interaction and geometry of the plates that make up the Mendocino Triple Junction. Every earthquake that occurs, I immediately look at its focal mechanism, and see if it fits the model we developed while at TERA Corp. So far, so good!
