SRL Call for Papers: 18 March 2020 Mw 5.7 Magna, Utah Earthquake

DEADLINE: 11 September 2020

The 18 March 2020 Mw 5.7 earthquake north of Magna, Utah (a suburb of Salt Lake City) occurred as the result of normal faulting in the shallow crust of the North America plate. This was the most significant earthquake in Utah since the M6.6 Hansel Valley event in 1934. The Magna earthquake was well recorded by a dense network of seismometers, continuous GPS stations, and satellite-based imaging techniques. The main event and associated aftershocks provide a unique opportunity to understand the geometry of the causative fault within the context of the greater Wasatch fault system.

SRL welcomes contributions to the focus section on this and other scientific aspects of this earthquake sequence such as earthquake source properties, near-field ground motions, geologic observations, damage assessments, aftershock forecasting, seismic hazard implications, and seismotectonics of the Wasatch Front urban corridor. Contributions can take the form of traditional research articles or Data Mine submissions. Data Mine submissions could include seismic data, GPS and InSAR measurements, surface deformation observations, as well as processed datasets such as relocated aftershock catalogs and slip inversions.

Guest editors for the SRL Focus Section on the18 March 2020 Mw 5.7 Magna, Utah Earthquake are Keith Koper (University of Utah) and Ryan Gold (U.S. Geological Survey).

Deadline for submission of manuscripts: 11 September 2020 Accepted articles will be published online as soon as ready and later in the March 2021 print issue.
