Yellowstone Nation Park

The park is a supervolcano so enormous, it has puzzled geophysicists for decades, but now a research group, using seismic technology to scan its depths, have made a bombshell discovery.


Yellowstone's magma reserves are many magnitudes greater than previously thought, say scientists from the University of Utah.

Underneath the national park's attractions and walking paths is enough hot rock to fill the Grand Canyon nearly 14 times over. Most of it is in a newly discovered magma reservoir, which the scientists featured in a study published on Thursday in the journal Science.
It may help scientists better understand why Yellowstone's previous eruptions, in prehistoric times, were some of Earth's largest explosions in the last few million years.

Yes the magma chambers are deeper and far larger than they thought.
So, I think Yes those earth quakes in Idaho are connected.

The Utah scientists also created the first three-dimensional depiction of the geothermal structure under Yellowstone, which comprises three parts.

Yellowstone's ultimate heat source reaches down 440 to 1,800 miles beneath Earth's surface -- and may come from its molten core.
It is responsible for fueling the newly discovered reservoir that lies on top of it.

The magma chamber, which scientists already knew about, lies on top of the reservoir -- and draws magma from it.
It is a three to nine miles under the surface of the Earth and is what fuels the geysers, steaming puddles and other hot attractions.

It alone has a volume 2.5 times that of the Grand Canyon.
But those great magma expanses do not mean that the two hellish hollows could overflow the Grand Canyon with molten rock.
