UUSS is hiring a Postdoctoral Research Associate and a Research Scientist this fall.

Postdoctoral Research Associate in Earthquake Seismology.
The successful applicant will work with UUSS faculty, staff, and students on problems related to induced seismicity. UUSS has active projects related to enhanced geothermal development, mining induced seismicity, and discrimination of explosions from earthquakes. Potential research topics include (1) discrimination of tectonic earthquakes from induced earthquakes and non-earthquake sources, (2) estimation of full moment tensors for small-to-moderate seismic events, (3) estimation of fault parameters of micro-earthquakes, (4) detection and high-resolution multi-event relocation of induced seismic sequences. While primary datasets are available from regional seismic networks, in some cases supplemental data will be generated using the University of Utah pool of over 150 three-component, short-period (5 Hz) Nodal seismometers.
The position is renewable for a second year pending acceptable progress and availability of funding. Opportunities for teaching, mentoring, and outreach will be made available for those interested in pursuing an academic track.
In addition to research, the successful applicant will be expected to serve rotations as a UUSS duty seismologist (leading the initial UUSS response to events of interest), which will periodically require 24/7 availability via cell/pager.
To apply submit a cover letter, a curriculum vitae, a statement of research interests, and contact information for three references using the following webpage: https://utah.peopleadmin.com/postings/80640.

M 3.8 near Cove Fort, Utah

Press Release

Released: September 12, 2018 12:50 AM MDT

The University of Utah Seismograph Stations reports that a small earthquake of magnitude 3.8 occurred at 11:34 PM on September 11, 2018 (MDT).  The epicenter of the shock was located in southwestern Utah in the southern Sevier Desert,  15 miles west-northwest of Cove Fort, UT.  This earthquake was followed by at least four aftershocks in the first hour, the largest of magnitude 2.3.  A total of 19 earthquakes of magnitude 3.0 or greater have occurred within 16 miles of the epicenter of this event since 1962.  The largest of these events was a magnitude 4.0 on February 23, 2001, 8 miles southwest of Kanosh, UT.

Anyone who felt the earthquake is encouraged to fill out a survey form on the US Geological Survey website:

Small Salt Lake City Earthquakes Felt and Heard

The University of Utah Seismograph Stations reports that four minor earthquakes of magnitude (M) 0.7 to 1.0 have occurred in northeastern Salt Lake City during the last eight days.  The first two earthquakes occurred on Sunday, September 2, at 02:13 am (M 0.7) and 10:33 am (M 1.0) MDT.  They were followed by an M 1.0 shock on Thursday, September 6, at 8:43 pm MDT and an M 0.8 shock at 3:48 pm MDT on Saturday, September 8.  These four earthquakes occurred near the southeastern part of the University of Utah campus at shallow depths of less than 3.5 miles.

Residents of northeastern Salt Lake City have reported feeling and/or hearing these earthquakes, in some cases describing the noise as a loud boom.  Earthquakes, especially very shallow ones, can generate noises that sound like booms or thunder to those nearby.  The sound is generated by seismic waves vibrating the ground surface up and down like a loudspeaker.

Small magnitude seismic activity like the recent activity in northestern Salt Lake City is a common occurrence in the Wasatch Front region.   The location of this recent activity appears to be too far east for it to be occurring on the Wasatch fault.

Anyone who felt or heard any of these earthquakes is encouraged to fill out a survey form which is available on the US Geological Survey website at https://earthquake.usgs.gov/data/dyfi/ .

1902 – Pine Valley, UT – M 6±

Intermountain Seismic Belt Historical Earthquake Project

November 17, 1902 – Pine Valley, UT – 6 ±

In the early afternoon of November 17, 1902 residents of Pine Valley, UT were startled by a magnitude 6 (+/-) earthquake. The shaking caused individuals to flee their homes, some being hit by swaying doors and jambs as they ran. Most of the chimneys in town were reportedly damaged. Clocks stopped. Some individuals reported seeing clouds of dust in nearby canyons as rocks weighing many tons came crashing down. Poultry and domestic animals were frightened. Some individuals reported that upon putting an ear to the ground, they could hear a low roar like a stove burning. Though residents were on edge day and night, no one was reported to have evacuated the area.

To the south, in St. George and Santa Clara, there were reports of considerable damage to many buildings. The shaking was strong enough in some buildings to flip hanging pictures completely over. Terrified children and adults ran from homes and other buildings, some experiencing the sensation of seasickness. Many residents were afraid to reenter their homes. Clouds of dust were seen in many directions from falling rocks as far as 25 miles away. It was reported that in some places, hot and cold springs were increased in their flows and waters became muddy.

The earthquake was reported felt in other cities and towns in the surrounding area including Bloomington, Pinto, Cedar City and Toquerville. Individuals in these areas reported damage such as toppled chimneys, falling ceiling plaster, cracked walls, items toppling from shelves, frightened people rushing from buildings and huge boulders rolling down causing clouds of dust. The communities of Lund, Notom, Parowan, Marysvale and Tropic reported feeling the earthquake but suffering no damage.

Felt reports from Salt Lake City mentioned stopped clocks and jarred nerves but no damage. One establishment reported a substance that appeared to be volcanic ash on its windowsills, causing some to question whether the earthquake had activated extinct volcanoes in the southern part of the state. Some individuals speculated that ash from such a volcano could have been carried northward by strong winds. Closer to the epicenter, a few individuals reported seeing smoke above the Pine Valley Mountains and some reported seeing a flash of fire lasting a few seconds, though others reported detecting no evidence of volcanic activity in the area.

On December 4, it was reported that not a day had passed since the initial shock without one or two earthquakes being felt in Pine Valley. A report from St. George on the same day noted that residents there were rejoicing in the belief that the earthquakes had finally ceased – at that point it had been four days since a shock had been felt.
