I live in North West Montana, and we had a pretty good earthquake the other night. I'm about ~200 miles from the epicenter. I assumed Yellowstone was fuckin blowing up lol. There was a 5.8 over by Helena or Lincoln or something. Earthquakes made me think of Yellowstone, which is a decent sized volcano I guess.... but of all that have happened in the lower 48, which is the biggest? Mt. St. Helens? All I find out is about hawaii
