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.
It's no reach to say that the ecosystem of Yellowstone National Park is one of the most dynamic and interesting in the world. It's a constantly changing environment that is not short on mystery. One of the biggest questions in the park over the past several years is why did Steamboat Geyser reawaken. A new study attempted to solve the mystery, but the conclusion is they still don't know.
Wyoming has earthquakes all the time. Most are in the western part of the state near the seismically-active Yellowstone. But, a moderate quake has just struck where we don't usually see earthquakes just south of the Bighorns.
Monday, August 17 will mark the 61st anniversary of the largest known earthquake that's ever hit Yellowstone. The magnitude 7.3 quake killed 28 and there are still remains in the park today showing what happened that day.
