Recent Earthquakes Near Tremonton, UT

University of Utah Seismograph Stations
Released: May 8, 2024 12:00 PM MDT

As of this morning, 89 earthquakes have been located in the sequence ~15 mi southwest of Tremonton, UT, with magnitudes ranging 0.8 to 4.4. Four events were M3 or greater, but most of the seismicity is below M2. The magnitude 4.4 event occurred on May 5, at 5:30 PM MDT and was reported to have been felt by more than 500 people on the USGS “Did You Feel It?” site.

Map of earthquakes in the area

Seismicity has occurred throughout this area, occasionally as clusters, in the 1980s through the early 2000s. Though there are a lot of earthquakes in the area in a short period of time, this type of activity is not uncommon. Typically we record an M4 earthquake about once a year in Utah. While it is possible for a larger earthquake to occur in this sequence, the probability of a larger future earthquake is low.

Earthquakes like these, that are felt but not damaging, are a great reminder of the earthquake threat in the Wasatch Front. The Wasatch fault system has the potential for a much larger earthquake, so it is important to practice earthquake safety and prepare your home.

Seismograph Technician Opening at UUSS

The University of Utah Seismograph Stations is seeking a specialist who will work under the supervision of other professional staff to operate, repair, and maintain 230 stations forming part of the University of Utah’s regional seismic network. Stations consist of seismic sensors, digital data acquisition systems, and associated telemetry equipment and are sited both in the urban built environment and in remote field locations throughout Utah and in parts of neighboring states. The Seismograph Technician will assist with the installation of new seismograph stations and maintain a detailed record of station visits and a written repair history for specified equipment items.

UUSS invited to become a formal Member-Institution of the International Seismological Centre (ISC).

The University of Utah Seismograph Stations (UUSS) is excited to announce it was recently invited to become a formal Member-Institution of the International Seismological Centre (ISC).

The ISC is a non-governmental, non-profit international organization which maintains extensive information about earthquakes and other seismic events from around the world. ISC members strive to collect, archive, and process seismic station and network bulletins and prepare and distribute the ISC bulletin – the definitive summary of the world’s seismicity.

Since its inception in the 1960s, the ISC has provided invaluable data used by thousands of seismologists worldwide. The current ISC mission is to maintain the ISC bulletin, the International Seismographic Station Registry, and the IASPEI Reference Event list. ISC also maintains several other important catalogs, contacts, and datasets.

The UUSS is honored to join the ISC. It joins 68 other research and operational organizations in 50 countries that support the ISC. Other ISC Members in the United States include NEIC/USGS, IRIS, and the TexNet of the University of Texas at Austin. The invitation to join comes as a great recognition of the important work of the UUSS on a national, and now international, scale.
