There is a major earthquake swarm underway under Yellowstone National Park with at least 78 quakes in the last day, but it's really not a reason for major concern.
We don't get earthquakes near Casper very often or at least the kind that you can really feel. I decided to do some digging and learned about some of the strongest quakes that have been felt in Casper and that includes 3 measurable ones in the last nearly 40 years.
Funny things happen when you try to constantly educate yourself. We know that there is a super-volcano in Yellowstone, but now I've learned there's also one in Utah and that's there's probably nothing to worry about. "Probably" is a very key word.
