The March 18, 2020 M5.7 earthquake north of Magna, Utah (just west of Salt Lake City) occurred as the result of normal faulting in the shallow crust of the North America plate. The focal mechanism solution for the earthquake indicates slip occurred on a moderately dipping fault striking either to the northwest, or to the south-southeast. The style, location, and depth of slip are consistent with an earthquake on the complex Wasatch fault system. This earthquake is located in the Intermountain seismic belt, a prominent north-south-trending zone of recorded seismicity in the Intermountain West, including the Wasatch Front urban corridor. The ISB region is 1000 km east of the primary North America–Pacific plate boundary which runs along the west coast of the United States.
Salt Lake City airport remains closed due to damage assessments.
