Yellowstone Supervolcano Earthquake Swarm Reaches 878 Events in Just Two Weeks

– June 27, 2017

Updated | Over 800 earthquakes have now been recorded at Yellowstone supervolcano over the last two weeks, with the ongoing swarm taking place on the western edge of the National Park.

But there is virtually no risk of the volcano erupting, the United States Geological Survey (USGS) currently lists the volcano alert level as normal and the aviation color, which lists the potential risk to fights, is at green.

The current earthquake swarm began on June 12. A week later, the USGS put out a statement to say that 464 earthquakes had been recorded, with the largest being magnitude 4.4 “This is the highest number of earthquakes at Yellowstone within a single week in the past five years,” it said.
