Updated | Yellowstone supervolcano has been hit by a series of earthquakes, with more 30 recorded since June 12. The latest was recorded on Monday, June 19, with a magnitude 3 earthquake striking 8.6 miles north northeast of West Yellowstone, Montana.
The swarm began last week, and on June 15 saw a magnitude 4.5 earthquake take place in Yellowstone National Park. “The epicenter of the shock was located in Yellowstone National Park, eight miles north-northeast of the town of West Yellowstone, Montana,” scientists from the University of Utah, which monitors Yellowstone Volcano, said in a statement.
“The earthquake was [reportedly] felt in the towns of West Yellowstone and Gardiner, Montana, in Yellowstone National Park, and elsewhere in the surrounding region.”
This earthquake was the largest to have hit Yellowstone since March 30, 2014, when a magnitude 4.8 earthquake was recorded 18 miles to the east, near the Norris Geyser Basin.
“[The 4.5] earthquake is part of an energetic sequence of earthquakes in the same area that began on June 12,” the statement continued. “This sequence has included approximately thirty earthquakes of magnitude 2 and larger and four earthquakes of magnitude 3 and larger, including today's magnitude 4.5 event.”
As of June 19, 443 events had been recorded. Most of these ranged in the magnitude of 0 to 1, with five less than zero, indicating they occurred at depths ranging from about 0 miles to about 9 miles.
But what would happen if it did erupt? In 2014, scientists with the USGS published a report where they modeled what would happen if a large, explosive eruption took place at the supervolcano. Their findings showed most of the country would be covered in a blanket of ash, with some areas being buried up to a meter deep.
