Two volcanic earthquakes have struck Idaho , and Wyoming over the past 12 hours. Both earthquakes related to the volcanic chambers below the famous Yellowstone Super-Volcano.

Both seismic events registered in the 3.0M+ range, and occurred directly along the line of the Yellowstone Magma chamber. One of the earthquakes struck directly inside of Yellowstone national park.

The underground magma chamber for the Yellowstone Supervolcano has now been confirmed to reach far West into Idaho, and North into Montana.

New measurements have also revealed that over 11 grand canyons worth of Magma (11,000+ cubic miles) is stored below this well known ‘supervolcano’.

The lower, larger magma chamber extends far West and North from the actual current Yellowstone National Park area.

This large magma chamber is showing earthquake activity due to pressure being placed on the magma chambers below via the North American Craton being displaced from the Pacific Northwest.

In addition to this Yellowstone earthquake activity, we have also seen multiple dormant volcanoes show earthquake activity over the past week all along the West coast of the United States.

There has even been an announcement that Glacier Peak Volcano in Washington State is now being monitored for possible eruptive activity.
