GREEN RIVER (WNE) — A mild earthquake was recorded northwest of Green River on Feb. 22, according to records from University of Utah seismograph stations.
According to the U.S. Geological Survey, the quake took place at 2:55 p.m. Friday and registered a magnitude 3.1. The shallow earthquake occurred at a depth of 1.7 kilometers.
The quake did not impact operations at Genesis Alkali. David Caplan, director of corporate communications for the facility, said the mine has emergency response plans for multiple scenarios, including seismic activity. However, the activity was so low it did not warrant a response under the emergency plan. Caplan said the mine has also cooperated with the University of Utah in monitoring seismic activity, saying the university installed an additional monitor within Genesis Alkali’s mine permit boundary in 2018.
According to information from the USGS website, eathquake.usgs.gov, few earthquakes are recoded east of the Intermountain Seismic Belt in the Uinta Mountains and nearby Wyoming Basin, with recorded earthquakes in the area tending to be small.
