The Search for the Dog Valley Fault


The Dog Valley fault (DVF) is an active left-lateral strike-slip fault that is responsible for the M6 Truckee earthquake (1966) — the largest earthquake yet recorded in the Tahoe-Truckee area of California and Nevada. Although the DVF is included in the Quaternary Fault and Fold Database of the United States, its ground-surface trace is not well established. Getting a better handle on this fault is important because another large earthquake on the DVF might endanger Stampede and Boca dams, whose failures would quickly send a significant volume of water and debris into downtown Reno. One estimate places the potential number of casualties related to sudden failure of these dams in the low six-figure range. This talk will summarize work that my students and I have done to locate this fault and understand its structural context.

Acknowledgements. This work was developed in collaboration with Kate Hobart, Matthew Strasser, Tyler Reed, Ryan Lindsay, Jeremy Ashburn, and Dan Lancaster. In addition to those colleagues, the Seismo-Lineament Analysis Method was developed along with Mark Millard, Brandon Rasaka, Victoria Worrell, Lauren Robinson, Brian Bayliss, Luke Pager, and Kelly Cronin Krein.
