Utah Quaternary Fault Parameters

The main goal of the Utah Quaternary Fault Parameters Working Group (UQFPWG) is to characterize active fault sources in Utah.

The working group began by developing consensus slip-rate and recurrence-interval data for all Utah trenched faults (Lund, 2005) in 2003 and 2004. The working group also developed an initial priority list of faults requiring additional study and, based on each year’s paleoseismic investigations, has updated the list annually.

As new paleoseismic data became available, the working group modified its consensus slip-rate and recurrence-interval values as necessary. The UQFPWG started annual meetings in 2005.
