Earthquakes in the Sawtooth Mountains of Idaho
For those interested in Idaho, the Sawtooth Mountains, or Earthquakes in general, here is a quick and dirty chronicle of our experience
The Sawtooth Wilderness is in Central Idaho on the Western Edge of a massive geologically active area extending East into Montana and Wyoming, and not coincidentally home to Yellowstone Park.
The Sawtooth fault, which runs along the east side of the Sawtooth Mountain range, is the largest and best known fault in the region. However, the Sawtooth fault is still not well understood. According to the Idaho Geologic Survey, we limited knowledge of the long-term slip rate and the timing of past earthquakes.

Were up early most days, and felt this one rattling the house at 5:30a in the morning. Third meaningful earthquake we have felt since moving back to Boise ~3 years ago.

Here's a great read from our friends at Sawtooth Mountain Guides. They were right in the middle of it.

On March 31, 2020, a magnitude 6.5 earthquake struck near Boise, ID, in the Challis National Forest
This one was scary. That's coming from a guy who was in Boise for the Borah Peak earthquake in '83, and experienced multiple smaller quakes living in Southern California. The house was shaking hard for what felt like 60-70 full seconds. I grabbed my daughter and headed for the strongest looking doorway I could find.
The Idaho Geologic Survey has the best summary of the technicals, if you're into that sort of thing.
