Yesterday (May 8th) I made a full post about how the 10 most recent earthquakes in California were at dormant volcanic locations.
This California dormant volcano movement follows the news that a new volcanic eruption is occurring off the West coast of the United States near Oregon.
Today (May 9th), we see a moderate magnitude 3.0 earthquake strike at the Westernmost portion of the upper Yellowstone magma chamber.
The magma chamber was verified to extend far West into Idaho, and North into Montana via new measurements done in 2014, and now again in 2015.
New Measurements were done on the underground magma chamber as of late April 2015.
They have found 11,500 cubic miles in a new LOWER chamber, the equivalent of over 11 grand canyons full of molten magma which feeds the upper chamber.
The upper chamber is one of the largest in the world already, with this new discovery about the 11 grand canyons worth of magma underneath Yellowstone, no doubt this is the largest supervolcano in the world for the moment.
See the new April 2015 Yellowstone magma chamber measurement results in the video below.
