BOISE, Idaho — Editor's note: The above video discusses how to prepare for an Earthquake in Idaho.
Idaho has had 341 confirmed aftershock earthquakes following the initial 6.5 magnitude earthquake that occurred on March 31. In the last week, there has been a total of 77 aftershocks, according to USGS.
All of the aftershocks have most frequently occurred around Challis, Cascade, and Idaho City, according to USGS.
The aftershock magnitudes range from 2.5 to 4.8 with the majority being in the 2.0 to 3.5 range. None of the confirmed aftershocks have been bigger or equal to the initial earthquake, which officials predicted would be the case.
The most recent aftershock occurred Wednesday morning at around 7:30 near Cascade and was confirmed to be of 3.6 magnitude.
The initial quake, which struck just before 5 p.m. Mountain Time on March 31, was centered about 45 miles west of Challis, in the mountains of Central Idaho. It was felt across Idaho and in six surrounding states.
