The supervolcano at Yellowstone National Park has been hit with more than 400 earthquakes since June 12. In a statement to the Star Valley Independent, scientists from the University of Utah -- which monitors the volcano -- said the earthquake swarms are nothing new. “This is the highest number of earthquakes at Yellowstone within a single week in the past five years, but is fewer than weekly counts during similar earthquakes swarms in 2002, 2004, 2008 and 2010,” scientists explained. "Earthquake swarms are common in Yellowstone and, on average, comprise about 50% of the total seismicity in the Yellowstone region," the University of Utah Seismograph Stations (UUSS) said in a statement on its website. There have been three major "caldera-forming eruptions" in Yellowstone in the last 2.1 million years, the last occuring 640,000 years ago.
