According to the United States Geological Survey, Yellowstone National Park typically experiences minor earthquakes of a magnitude 2 or below on the Richter Scale. On Tuesday, May 11, that was not the case when a magnitude 4.2 earthquake rattled Yellowstone.
I will admit that I'm an earthquake nerd, so I tend to follow earthquakes pretty much all around our region. However, I don't recall ever seeing one happen in the Black Hills of South Dakota...until today.
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.
