Rich D. Koehler

Nevada Bureau of Mines and Geology
Associate Professor

Expertise: My work is focused on earthquake geology, Quaternary geology, paleoseismology, geomorphology, and engineering geology. I have experience evaluating regional neotectonics, as well as paleoseismic histories on individual faults.
