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.

Utahns ‘lulled into a false sense of security’ in earthquake prep
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.
We hope you all had an enjoyable and safe long Labor Day weekend! Here’s a little story for the Tuesday morning catchup. A research team, including some of our UGS geologists, are studying a portion of the Taylorsville-West Valley City Fault to gain a better sense of past earthquakes on the fault. Read more!

A research team is digging up a portion of the Taylorsville-West Valley City Fault out by the Salt Lake City International Airport, and their goal is to get a better sense of the danger from that fault and how big of an earthquake it could create.
For this #tbt we’re looking at Mount St. Helens and the beginning of its 2004 eruption. While it wasn’t to the magnitude of its notable 1980 eruption, the 2004-08 eruption resulted in a remarkably rapid, though nearly steady, rate of dome growth. Check out the U.S. Geological Survey (USGS)‘s youtube video for a time lapse of the dome on Mount St. Helens! #throwbackthursday

Celebrate the third annual Geologic Map Day! On October 17, as a part of the Earth Science Week 2014 activities, join leading geoscience organizations in promoting awareness of the importance of geologic mapping to society.
Good morning geo friends! The U.S. Geological Survey (USGS) has recently updated their U.S. National Seismic Hazard Maps, which reflect the best and most current understanding of where future earthquakes will occur, how often they will occur, and how hard the ground will likely shake. While earthquakes remain hard to predict, the USGS hopes to understand how earthquakes might affect areas specifically to better plan for the event.

To help make the best decisions to protect communities from earthquakes, new USGS maps display how intense ground shaking could be across the nation.
Among the more commonly asked questions we receive at the Utah Geological Survey (UGS) are those dealing with the correct names of Utah’s geographic features.
Perhaps the best tool for answering these questions is a searchable database established and maintained by the U.S. Board on Geographic Names, which is part of the U.S. Geological Survey (USGS). This database, called the Geographic Names Information System (GNIS), is available online at geonames.usgs. gov.
Following the American Civil War, a surge of exploration, mining, and settlement of western territories created many inconsistencies and contradictions in geographic names, which became a serious problem for surveyors, map makers, and scientists.
To address this problem, President Benjamin Harrison signed an executive order that created the U.S. Board on Geographic Names in 1890 (the current form of the board was established by a 1947 law). Technology, such as geographic information systems, global positioning systems, and the Internet increases the need for standardized data on geographic names, but it also makes accessing that data quick and easy through the GNIS.
The Utah Geological Survey (UGS) and U.S. Geological Survey (USGS) have a cooperative agreement to study earthquake-hazards in Utah with an ultimate goal of producing detailed earthquake-hazards maps, including large-scale ground-shaking maps along the densely populated Wasatch Front urban corridor.
An important component of the ground-shaking maps is developing a three-dimensional model of the subsurface, a Wasatch Front Community Velocity Model (CVM), that incorporates shallow shear-wave velocity (Vs), deep-basin structure, and other effects. To aid in producing these maps, the UGS has compiled databases of Vs and deep-basin geophysical and well logs.

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.
