Thanks to a recent earthquake swarm, the Yellowstone supervolcano has seen upwards of 200 quakes since February 8, along with countless smaller tremors.
swarms occur when a single area experiences an increase in quakes over a short period of time without the trigger of a single, larger “mainshock.” Swarms can result from changes in stress along fault lines, which can be caused by either large-scale tectonic forces or pressure buildup due to changes in magma, water, or gas underneath Earth’s surface.
2,400 earthquakes between June and September 2017.
there’s no way to tell when the supervolcano actually is going to blow.
