INTRAPLATE EXTENSIONAL TECTONICS OF THE EASTERN BASIN-RANGE: INFERENCES ON STRUCTURAL STYLE FROM SEISMIC REFLECTION DATA, REGIONAL TECTONICS, AND THERMAL-MECHANICAL MODELS OF BRITTLE-DUCTILE DEFORMATION. In August 2015, the UGS, aided by the U.S. Geological Survey (USGS), conducted a paleoseismic (fault trenching) investigation of prehistoric surface-faulting earthquakes on the Taylorsville fault. Monday through Friday, Utah has experienced many earthquakes, large and small, because of its abundance of faults and fault zones. 1594 West North Temple, Suite 3110 Trenches at the Airport East trench site exposed geologic evidence for three surface-faulting earthquakes on the Taylorsville fault. Our preliminary findings include evidence for three post-Bonneville earthquakes at the Airport East site and distinguish seven separate units in the trench wall. Groundwater at the site was very shallow, which was problematic for trench wall stability and prevented us from trenching deeper to expose older deposits that might record a more complete earthquake record. SALT LAKE CITY -- Scientists have discovered evidence of four big earthquakes that rocked the Salt Lake Valley long before pioneers arrived -- and they're not on the well-known Wasatch Fault on the East Bench.
8 a.m. to 5 p.m. Several specialized programs comprise the UGS: Energy & Minerals, Geologic Hazards, Geologic Information & Outreach, Geologic Mapping, Groundwater & Wetlands, and Paleontology. We will use the data to develop a model for the timing of prehistoric earthquakes at the Airport East site, as well as refine data from past trench investigations. Several units in the trench were very organic rich and one contained a burn horizon. Reading or replaying the story in its archived form does not constitute a republication of the story.

If they can figure out whether the two fault zones are structurally related, it could sharpen scientists' understanding of what to expect in the future. The abundance of organic material allowed us to collect samples with numerous discrete charcoal fragments, which makes dating the material easier. 14-08-0001-G1397, LockA locked padlock | United States.

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. In Salt Lake Valley, strands of the Salt Lake City segment of the fault zone pass directly through Utah’s capital city. These units consist of sand and silt deposits, probably deposited on the paleo-Jordan River floodplain and Great Salt Lake margin marshes over thousands of years. These data will help us better understand the complex relationship between earthquakes on the West Valley fault zone and the Salt Lake City segment, increase our knowledge of the entire Wasatch fault zone, and will eventually be incorporated into the USGS National Seismic Hazard Maps that are part of the International Building and Residential Codes adopted in Utah.
Although few Utahns are familiar with this system of faults in northern Salt Lake Valley, the West Valley fault zone is an active geologic structure and shares an interesting relationship with the well known Wasatch fault zone.

The horizontal layers of sediment show clear signs of being broken by fault movements. OF THE WEST VALLEY FAULT ZONE, SALT LAKE CITY URBAN AREA ABSTRACT The West Valley fault zone (WVFZ). Official websites use .gov Monday through Friday, Utah Faults. Over the last decade the shrinking lake receded several miles from the fault zone, and the water table has dropped. John Hollenhorst
The samples are currently being processed, and we are awaiting results. To the west, in urban Salt Lake City, a 4-mile-wide (6 km) zone of fault segments called the West Valley Fault Zone stretches north-northwest for 9 miles (14 km) beneath the valley. You are currently offline. The West Valley Fault zone is actually comprised of a dozen different fractures. The West Valley fault zone is the lesser known of the two major faults that run through the Salt Lake Valley (the other is the Salt Lake City segment of the Wasatch fault zone). West Valley City, Utah does utilize Daylight Saving Time. "The type and strength and duration of ground-shaking may change with this work," DuRoss said. Currently, about 80% of Utah's population live along the Wasatch Fault, representing the largest earthquake threat in the interior Western U.S. On the west end of Salt Lake Valley is another fault zone called the West Valley fault zone that spans 9 miles (16 km) north-northwest. The west segment, known as the West Valley Fault (WVF) is one of the two major fault segments of the Valley Fault System which runs through Metro Manila to the cities of Marikina, Quezon City, Pasig, Makati, Taguig and Muntinlupa and moves in a dominantly dextral strike-slip motion. about viewing, downloading, and printing report files can be found here. Funding for this project was provided through the USGS National Earthquake Hazards Reduction Program (NEHRP). "I think the best answer is that we should all be prepared for an earthquake at any time, whether it's on the West Valley Fault zone or the Wasatch Fault zone.". 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. That would imply bigger quakes than scientists previously suggested. "We suspected that there had been numerous earthquakes in this region," said Chris DuRoss of the Utah Geological Survey. Salt Lake City, Utah 84114. Although few Utahns are familiar with this system of faults in northern Salt Lake Valley, the West Valley fault zone is an active geologic structure and shares an interesting relationship with the well known Wasatch fault zone. We collected samples for both radiocarbon (14C) and optically stimulated luminescence (OSL) dating methods. The Wasatch fault zone has long been known to be a serious earthquake threat to the Wasatch Front region. 8 a.m. to 5 p.m. They lie roughly between Redwood Road and 5600 West from about 1700 North to 4800 South.
What is an Earthquake Early Warning System and Does Utah Have One? Glad You Asked: Ice Ages – What are they and what causes them? Lying within the Intermountain Seismic Belt and long recognized as the western boundary Glad You Asked: Ice Ages – What are they and what causes them? The Magna earthquake should be a reminder that Utahns live in earthquake country, and that there is a reasonable chance that people living in Utah today could experience a large earthquake in their lifetime. Part or all of this report is presented in Portable Document Format Monday through Friday, The evidence in the trenches suggests that each of the four earthquakes on the West Valley Fault system was strong enough to break the ground.
