Powerful Aftershock Rocks Area Near Soda Springs

A 4.1 magnitude earthquake on Tuesday evening near Soda Springs is being considered an aftershock from the Sept. 2 Sulpher Peak Earthquake.

Jim Pechmann, a seismologist with the University of Utah Seismograph Stations, said the earthquake occurred approximately 12 miles southeast of Soda Springs around 7:30 p.m.

Officials with the U.S. Geological Survey reported that there had been more than 1,900 aftershocks as of mid-September, and even more have followed.

USGS officials say the sequence has been a particularly active one and has produced more aftershocks on average than other earthquakes of a similar magnitude.

From Oct. 3 to Oct. 11, USGS’s website said that there were 73 total earthquakes recorded near Soda Springs.

As of 8 p.m. on Wednesday, 40 more smaller earthquakes had followed the magnitude 4.1 event on Tuesday, according to the USGS website. There have been no reports of structural damage or injuries from the quakes on Tuesday and Wednesday.

USGS officials say there is a less than 1 percent chance that a much larger earthquake — up to magnitude 7 — could occur.
