The University of Utah Seismograph Stations reports that a small earthquake of magnitude 2.3 occurred at 11:18 PM yesterday evening, October 9, 2020 (MDT). The shock was located 6.6 miles beneath the northwestern part of the Salt Lake Valley, 2.9 mi E 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 hundreds of residents of the Salt Lake Valley. To date, the University of Utah Seismograph Stations has located 2,498 aftershocks from the March 18 earthquake, including 115 of magnitude 2.3 or larger and 40 of magnitude 3.0 and larger. In recent weeks there has been, on the average, approximately one aftershock per day 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.
