PROPOSED UPDATES TO THE IDAHO FAULT DATABASE

The Idaho fault database, which includes Miocene and younger faults, was compiled and published in 2003 (Breckenridge et al. 2003) by the Idaho Geological Survey (IGS). An electronic version of the database was released in 2006 and it has since been updated sporadically. IGS is systematically updating the database in order to better characterize fault hazards, provide more thorough source documentation, and improve data availability. Recently collected high resolution imagery and elevation data allows for more detailed fault mapping at larger scales. The updates and revisions will also help make the database more compatible with seismic hazard analysis by following a database format similar to the Third Uniform California Earthquake Forecast (UCERF3; Field et al. 2013). This poster presents the current state of the fault database, and describes the proposed structure of the revised database. The poster will also highlight several priority faults in Idaho, including: Squaw Creek fault, Boulder Front fault, Sawtooth fault, Lost River fault, Lemhi fault, Beaverhead fault, Bear Lake faults, West Cache fault, and Malad segment of the Wasatch fault.
