A magnitude 4.3 earthquake apparently left over from a bigger tremor in September was widely felt in southern Idaho, northern Utah and western Wyoming.
The U.S. Geological Survey said the at about 8:30 p.m. local time Thursday was centered about 8 miles southeast of Soda Springs, Idaho, a town of about 3,000 people, The Associated Press reported.
The tremor was felt 150 miles to the south in Salt Lake City and in much of western Wyoming.
There were no reports of any damages or injuries.
Seismographers from the University of Utah said the quake is an aftershock of a 5.3 magnitude earthquake in the area in September. That quake brought a swarm of hundreds of aftershocks in the weeks that followed.
