Scientists help builders, planners prepare for Utah’s big quake
Utah’s seismic scientists are sounding a warning about impending earthquakes in Utah. They say Utah is not prepared for a major earthquake even though science tells us it is when, not if, one will hit the Wasatch front.

Experts suggest Utah unprepared for possibility of powerful earthquake
Experts say the state of Utah is not prepared for a big earthquake, and seismologists at the Earthquake Research Institute predict if a 7.0-magnitude quake hit the Wasatch Fault Line it would cost the state about $33 billion in economic losses.

Utah not ready for a major earthquake
A new study says Utah is not ready for a major earthquake.
Take a quick minute today on your afternoon break to think about earthquake preparedness. What have you done around your home to help relieve potential damage from a large earthquake? Have you talked to your family and friends, do you have an action plan if an earthquake occurs?
A team of geologists, including some of our very own Utah Geological Survey geologists, have been studying the Taylorsville-West Valley City fault over the last couple of weeks. They hope to gain a better understanding of the fault’s ability to produce large earthquakes, and if that fault tends to rupture with or without the Wasatch Fault. Below are a couple of articles outlining all of their hard work and findings!

Geologists sample Taylorsville-West Valley fault line to study earthquake risk
A team of geologists has dug a 150-foot trench by the Salt Lake City International Airport to study the Taylorsville-West Valley City fault, and its rock samples will help scientists forecast when the next major earthquake could erupt along the Wasatch fault.

This 1:24,000-scale surface fault rupture map of the Honeyville quadrangle shows potentially active faults and special-study areas for the Brigham City and Collinston segments of the Wasatch fault zone mapped using primarily 0.5-meter digital LiDAR data acquired in 2013 and 2014. Fault traces were also mapped using black and white stereographic and oblique aerial photographs and previous published sources for the Wasatch fault zone and parts of the West Cache fault zone contained on the Honeyville quadrangle.

“Geologic Remapping of the Warm Springs Fault”
presented by Adam McKean, Mapping Geologist with the UGS
The Warm Springs fault of the Wasatch fault zone is a down-to-the-west normal fault, bounding the western portion of the Salt Lake salient. Recent geologic remapping of the Salt Lake City North 7.5-minute quadrangle has provided us an opportunity to revisit the Warm Springs fault and its place within Salt Lake and Davis Counties. A draft map of the quadrangle and evidences for the Warm Springs fault location will be presented at the meeting with opportunities for open discussion, questions, and feedback. We invite the geologic and geologic engineering community and interested parties to attend the event and take part in this public comment period.
Happy Monday! We hope you all had a great weekend. Here’s an article for your afternoon read—sometimes scientists will go the distance to learn about our local surroundings.

The Salt Lake City segment (SLCS) of the Wasatch fault zone and the West Valley fault zone (WVFZ) are Holocene-active faults that have evidence of large-magnitude (M ~6-7) surface-faulting earthquakes. Paleoseismic research trenches at the Penrose Drive site on the SLCS and Baileys Lake site on the WVFZ provided data that shed light on the faulting behavior and interaction of these graben-forming fault systems. Numerical age control (22 radiocarbon samples 23 optically stimulated luminescence samples) and OxCal modeling of six or seven surface-faulting earthquakes on the SLCS and four earthquakes on the WVFZ helped refine the earthquake chronologies for these faults and allowed a comparison of the chronologies to evaluate fault interaction. The chronologies, as well as vertical displacements, support a model of coseismic fault movement.
PALEOSEISMIC INVESTIGATION OF THE NORTHERN WEBER SEGMENT OF THE WASATCH FAULT ZONE AT THE RICE CREEK TRENCH SITE, NORTH OGDEN, UTAH
Christopher B. DuRoss, Stephen F. Personius, Anthony J. Crone, Greg N. McDonald, David J. Lidke
This report presents new paleoseismic information for the northern Weber segment of the Wasatch fault zone, collected as part of a joint Utah Geological Survey and U.S. Geological Survey fault-trench investigation at Rice Creek. This research, which was partially funded through the National Earthquake Hazards Reduction Program, expands the record of Weber-segment paleoearthquakes into the early Holocene, provides new timing and displacement data for the most recent earthquake, and helps reduce uncertainties in earthquake timing, recurrence, displacement, and vertical slip rate. These results are important for understanding segmentation of the northern Wasatch fault zone and for improving earthquake-hazard evaluations of the region.
