I must confess that I am a volcano nerd. I've been fascinated with them dating back to the Mt St. Helens eruption in 1980. My fascination with this part of geology led me to ask the question what would it really take to make the Yellowstone supervolcano erupt? This is what I found.
Yup, you probably felt the rolling shortly before 6pm on Tuesday night. A 6.5 earthquake shook through Idaho and was felt in many areas of southwest Montana.
