The USGS has released an information page for the Sulphur Peak earthquake sequence near Soda Springs, ID. This page includes earthquake forecast models and three possible scenarios for the next week.
On September 02, 2017, in eastern Idaho near the town of Soda Springs a magnitude 5.3 earthquake was widely felt through our southeastern Idaho and Northern Utah. Seismicity has continued to be very active including 158 earthquakes larger than M 3. These earthquakes occur slightly outside of the University of Utah Seismograph Stations area of responsibility, but the area is of interest to UUSS and the USGS Earthquake Hazards Program.
UUSS in partnership with USGS have deployed two UUSS 3-channel strong-motion systems and six USGS 6-channel seismic systems (broadband and strong-motion) within 5-40 km of the seismicity. These stations can be seen on the map below as well as links to the webicorders for the temporary stations.

The University of Utah Seismograph Stations reports that a moderate
earthquake of magnitude 5.3 occurred at 05:57 PM on September 02, 2017
(MDT), as computed by the USGS. The epicenter of the shock was located
11 mi E of Soda Springs, ID. This event was preceded by a magnitude 4.3
foreshock and followed by numerous aftershocks, including seven with
magnitudes between 3.2 and 4.1 (all USGS magnitudes).
The 5.3 mainshock was reported felt in Idaho, Wyoming, and also across
northern Utah in the cities of Logan, Bringham City, Ogden, Salt Lake City,
Draper, and Provo.
Since 1962, a total of 87 earthquakes of magnitude 3.0 or greater have
occurred within 16 mi of the epicenter of today’s magnitude 5.3 event.
The largest of these events was a magnitude 4.7 on October 13, 1982,
