The University of Utah Seismograph Stations (UUSS) has maintained a seismometer network in Utah and surrounding regions since 1966. The primary purpose of this network is to detect and locate regional earthquakes so that seismic hazard in the area can be better quantified. The seismic hazard and risk in Utah are severe with 80% of Utah’s 2.8 million people living and working along the Wasatch Front urban corridor, many in unreinforced masonry structures in close proximity to the Wasatch fault. Exploratory trenching and fault‐scarp morphology analyses indicate that moderate to large magnitude earthquakes (M 6.5–7.5) occur repeatedly on the...
