Wasatch Fault Zone Map. The new map shows earthquakes within and surrounding Utah from 1850 to 2016, and faults considered to be sources of large earthquakes. - Articles from The Weather Channel | weather.com Large Earthquakes on the Wasatch Fault Scroll through this Story Map to learn when large earthquakes have occurred on the Wasatch fault in the past. segment and multisegment … The Wasatch fault will generate large earthquakes in the future; many may … Public access for the new mapping can be accessed here. Gilbert was observing the central segments of what we now call the Wasatch fault zone. “People still have to determine what their individual risk is, we can't determine what their risk is. Planets, Magnetospheric This zone consists of a series of normal faults in ten active segments along a 250-mile-long stretch from north of Malad City, Idaho, to south of Fayette in central Utah. On the valley or “downthrown” side of the fault, the ground can crack, tilt and fault as well. In active faults like we have here in Utah, pieces of the earth’s crust move over time. Properties of Rocks, Computational U.S. Geological Survey, Golden, Colorado, USA, U.S. Geological Survey‐Emeritus, Golden, Colorado, USA, Olig Seismic Geology, Inc., Martinez, California, USA, Formerly at URS Corporation, Seismic Hazards Group, Oakland, California, USA, Utah Geological Survey, Salt Lake City, Utah, USA, Utah Geological Survey‐Emeritus, Cedar City, Utah, USA, U.S. Geological Survey, Menlo Park, California, USA. New maps show the full extent of Utah's Wasatch Front fault lines, which could cause a significant earthquake. Geophysics, Marine Oceanography, Interplanetary The idea is that people will be able to interact with the data more easily. Physics, Solar On average the segments are approximately 25 miles (40 kilometres) long, each of which can independently produce earthquakes as … What is a scarp? Some of the most active faults in Utah include the Wasatch fault along the Wasatch Front, the Hurricane fault in Southern Utah, and the Needles fault zone in Canyonlands National Park. Is northern Utah susceptible to a similar earthquake? Hours: 8:00 am - 5:00 pm Mon-Fri. 55 S 500 E Heber City, Utah 84032. The 240-mile-long Wasatch fault extends from north of Malad City, Idaho, to Fayette, Utah. Learn more. Geology and Geophysics, Physical From Machette and others (1987, 1991). - Articles from The Weather Channel | weather.com (1896-1977), Chinese Journal of Geophysics (2000-2018), International Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username, Journal of Advances Journal of Geomagnetism and Aeronomy, Nonlinear Physics, Comets and Provo sagment (between solid stars) is composed of the American Fork, Provo, and Spanish Fork sections (between solid and hollow stars). Faults in the Wasatch Front are capable of generating earthquakes approximately up to magnitude 7.6, releasing about 700 times more energy than the Magna earthquake. Take a look at the UGS interactive map. The new mapping Kleber is talking about is being done in collaboration with the U.S. Geological Survey and uses high-resolution elevation surveys (lidar), previous mapping, studies of ancient earthquakes and field mapping to map new fault traces and increase the detail on existing fault traces. Use the link below to share a full-text version of this article with your friends and colleagues. At magnitude 6.5 an earthquake can rupture the ground surface producing a fault scarp, uplift, of several inches to up to 20 feet high, extending for up to 40 miles. materials and the geologic units in a stratigraphic framework that evolved over the past three decades. maps of the Wasatch fault zone, depicts the surficial deposits and faults along the Weber segment and part of the adjacent Salt Lake City segment of the Wasatch fault zone in northern Utah (fig. Physics, Astrophysics and Astronomy, Perspectives of Earth and Space Scientists, I have read and accept the Wiley Online Library Terms and Conditions of Use, Journal of Geophysical Research: Solid Earth. The 240-mile-long Wasatch fault extends from north of Malad City, Idaho, to Fayette, Utah. Feeling the shake in Cache Valley surprised and alarmed many northern Utah residents. CENTRAL WASATCH FAULT ZONE SEGMENTATION 1133 . The Report of Investigations 280 can be accessed here. A fault forms the boundaries between the Earth’s tectonic plates. Fault segmentation: New concepts from the Wasatch Fault Zone, Utah, USA Christopher B. DuRoss1, Stephen F. Personius1, ... Base map is 10m digital elevation model [Utah Automated Geographic Reference Center, 2015]. Using high-resolution elevation data (lidar), UGS geologists mapped fault traces (bar and ball on downthrown side of fault) and defined special study zones along the Wasatch Front. Journal of Geophysical Research: Solid Earth 10.1002/2015JB012519 DUROSS ET AL. and Chemical Oceanography, Physical Geophysics, Mathematical Index map showing trace of Wasatch fault zone. Please check your email for instructions on resetting your password. Phone (435) 657-3194 IS@wasatch.utah.gov The faults shown on the map are considered geologically active, have been sources of large earthquakes (about magnitude 6.5 and greater) during the Quaternary Period (past 2.6 million years), and are the most likely sources of large earthquakes in the future. Kleber said the UGS is actively working to make data on geologic hazards more accessible to the public, including local governments, developers and individual homeowners. The fault is made up of ten segments, five of which are considered active. Residents throughout Utah were shaken out of their sleep by a magnitude 5.7 earthquake near Magna earlier this week. This is the first map that is sufficiently detailed to be useful for interpreting the paleoseismic history of this part of the Wasatch fault zone. While the recent Magna earthquake may have taken many Utahns by surprise, geologists at the Utah Geological Survey were hard at work finishing a four-year, fault-mapping study they hope will help reduce earthquake risks in the state. Salt Lake City Earthquake Faults including Wasatch fault zone, West Valley fault zone, East Great Salt Lake fault zone, Southern Oquirrh Mountains fault zone, East Canyon fault, and Utah Lake faults. Compared to previous mapping, geologists located more surface fault traces giving us a better idea of how to live in earthquake country. The Wasatch fault is a major active fault that extends from near Gunnison on the south, northward into southern Idaho traversing through the most densely populated areas of Utah as shown on Figure 1. So the message we try and give people is, you know, we help you understand the hazards, but you have to figure out what your risk is," Kleber said. The Wasatch Fault is also known as the Wasatch fault zone (WFZ) since it isn't a single long fault, but rather a … Some of the most active faults in Utah include the Wasatch fault along the Wasatch Front, the Hurricane fault in Southern Utah, and the Needles fault zone in Canyonlands National Park. The Wasatch fault is one of the longest and most active faults of its type in the world. Geophysics, Biological Geophysics, Geomagnetism Tap to read full story. and Paleomagnetism, History of “So these are just sort of our best way to help communicate the surface fault rupture hazard, and encourage the need to develop ordinances around building around and on top of fault zones.”.
