The University of Utah Seismograph Stations reports that a minor earthquake of magnitude 3.6 occurred at 06:45 PM on July 16, 2021(MDT). The epicenter of the shock was located beneath Yellowstone Lake, 7.4 mi SSE of Fishing Bridge, WY.  This earthquake is part of an intense sequence of small earthquakes, known as a swarm, that began yesterday afternoon (July 15).  There have been approximately 200 earthquakes in this swarm so far, including three others of magnitude 3.0 or larger and approximately 40 in the magnitude range 2 to 3.  Earthquake swarms are common in the Yellowstone National Park region, and account for roughly half of the total seismicity in the Yellowstone region.  The current swarm is occurring in an area that has had swarm activity in the recent past, including the 2008-2009 Yellowstone Lake swarm that included over 800 earthquakes.

Anyone who felt the earthquake is encouraged to fill out a survey formon the US Geological Survey website: earthquake.usgs.gov.

The University of Utah Seismograph Stations reports that a small earthquake of magnitude 2.5 occurred this afternoon at 3:17 PM, November 18, 2020 (MST).  The shock was located 6.2 miles beneath the northwestern part of the Salt Lake Valley, 3 mi east northeast of the town of Magna, UT.  This earthquake was an aftershock of the magnitude 5.7 earthquake that occurred in the same area on March 18.  Today’s aftershock was felt by more than one hundred residents of the Salt Lake Valley. To date, the University of Utah Seismograph Stations has located 2,531 aftershocks from the March 18 earthquake, including 75 of magnitude 2.5 or larger and 40 of magnitude 3.0 and larger. In recent weeks there have been, on the average, approximately six aftershocks per week large enough to locate, most of them smaller than magnitude 2.0.  Aftershock activity is expected to continue for months, but with the rate continuing to decrease with time.
