Utah Earthquake Working Groups

In 2003, the UGS and U.S. Geological Survey (USGS) established four multi-disciplinary earthquake-working groups (Utah Quaternary Fault Parameters Working Group, Utah Liquefaction Advisory Group, Ground Shaking Working Group, and the Earthquake-Induced Landslide Working Group) to coordinate earthquake research in Utah.

These working groups have met each year since 2003, to review research activities, re-evaluate long-term plans for producing earthquake hazard maps, and develop partnerships for investigations. However, the Earthquake-Induced Landslide Working Group has been inactive since 2005.

In 2006, the UGS, Western States Seismic Policy Council (WSSPC), and the USGS established the Basin and Range Province Earthquake Working Group (BRPEWG) to develop Basin and Range Province seismic-hazard consensus recommendations related to future updates of the USGS National Seismic Hazard Maps. BRPEWGI met in 2006, and BRPEWGII met in 2011.

In 2010, the Working Group on Utah Earthquake Probabilities (WGUEP) was established to support the estimation of probabilities of large earthquakes along the Wasatch Front. The WGUEP will meet about three times per year until the earthquake probability project is completed.

The working group process is funded through a cooperative agreement between the UGS and USGS National Earthquake Hazards Reduction Program (NEHRP).

Working group members include geologists, engineers, seismologists, and geophysicists from the University of Utah, Utah State University, Brigham Young University, UGS, USGS, U.S. Bureau of Reclamation, and various consulting companies and other government agencies.

The 2016 meetings of the Utah Quaternary Fault Parameters Working Group, Utah Liquefaction Advisory Working Group, Utah Ground Shaking Working Group, and the Working Group on Utah Earthquake Probabilities will be held in Salt Lake City February 8-11.
