Event Summary

A magnitude 5.7 earthquake occurred at 13:09:31 UTC (07:09:31 local) on March 18, 2020, 6 km NNE of Magna, Utah. For more information, see the USGS Earthquake Hazards Program event page.

The event occured within the Network of the Americas (NOTA) footprint. NOTA is a core component of the NSF Geodetic Facility for the Advancement of Geoscience (GAGE), operated by UNAVCO.

GAGE Response

NOTA GPS/GNSS Real Time Data Solutions
This earthquake was too small to result in detectable motion above station noise for the seven NOTA stations with real-time capabilities closest to the earthquake's epicenter (Figure 2).

NOTA GPS/GNSS High-Rate Data for Post Processing
UNAVCO downloaded high-rate 1- and 5-sps (1 and 5 Hz) data from all NOTA GPS/GNSS stations within 70 km of the earthquake epicenter with available data for a 3-hour time window centered on the event (Figure 1). When downloaded, these data will be available in RINEX format from the UNAVCO high-rate data ftp site.

GAGE GPS/GNSS Displacement Estimates
Coseismic offsets will be estimated for stations for which we anticipate offsets >5 mm. Any offsets will be posted to the UNAVCO Data Products page.

NOTA Borehole Strainmeter Data
A fully processed 1-sps borehole strainmeter (BSM) dataset for this event has been produced. This dataset can be downloaded from the UNAVCO borehole strainmeter event response page. See figures for examples of signals recorded by the BSM network.

Note: Figures and findings are preliminary and subject to revision.
