According to USGS, 72 earthquakes have hit Yellowstone in the last 24 hours… And the seismic unrest doesn’t seem to stop.
The smaller quakes are starting to work their way toward the Caldera area.
This swarm was set off by a shallow 4.5 earthquake on June 16, 2017. We also have NASA flying the largest Infrared Observatory in the world over the Supervolcano.
