On the morning of Wednesday, March 18, 2020, northern Utah experienced a magnitude (M) 5.7 earthquake with an epicenter north of Magna, Utah.
The University of Utah Seismograph Stations has located 2,320 earthquakes that occurred in the Magna, Utah, area from March 18 through June 24. The largest of these earthquakes was the magnitude (M) 5.7 mainshock that occurred at 7:09 am on Wednesday, March 18. The remaining 2,319 earthquakes are aftershocks. The largest aftershocks were two M 4.6 events that occurred at 8:02 am and 1:12 pm on Wednesday, March 18. Two M 4.2 aftershocks occurred on April 14 and 17th which were widely felt along the Wastach Front. There have been 40 aftershocks of M 3 and larger.
Field teams of geologists from the Utah Geological Survey mobilized to look for evidence of surface fault rupture, liquefaction, lateral spread, and other geological effects from the earthquake.
