The University of Utah Seismograph Stations reported that 139 earthquakes have occurred in the city of Bluffdale over the last 12 days, sparking new light amid unusually frequent shakes happening in Northern Utah.

According to the seismograph station, the largest earthquake occurred in the early morning on Friday, February 15 which was a 3.7M quake. Only 13 of those happened before the largest earthquake.

Of the remaining 125 quakes, they were aftershocks, the largest occurring on last Saturday at 2:31 a.m.

The university says that those earthquakes are not related to the 4.0M earthquake that happened Wednesday, February 20 near Kanosh.
