AMERICANALMANAC (Charles McAdams) - Magnitude 3.3 earthquake strikes Yellowstone near the supervolcano that keeps geologists watching
A magnitude 3.3 earthquake shook Yellowstone National Park on Thursday morning, its epicenter running along the Yellowstone River roughly 24.2 miles from Mammoth, squarely inside the footprint of one of the most closely monitored volcanic systems on Earth. The U.S. Geological Survey recorded the quake at approximately 1:20 p.m. UTC, 8:20 a.m. Eastern, at a […] The post Magnitude 3.3 earthquake strikes Yellowstone near the supervolcano that keeps geologists watching appeared first on American Almanac .
