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.
