Magma chamber under Yellowstone 'grows'

Scientists, utilizing the latest seismic technology, have determined that the magma chamber beneath the Yellowstone National Park caldera is actually 2.5 times larger than previously thought. They are quick to point out, however, that this discovery does not necessarily increase the chances for an eruption of the VEI 8 volcano, though they remain very concerned about earthquake activity in the volatile region.

This data suggests that the magma chamber is only at 7% of capacity, and while the gaseous pressure within is enough to cause rising and falling of the caldera floor it is insufficient for triggering a massive eruption. However, due to geological forces literally 'stretching' the region Yellowstone's crust is slowly being thinned, raising the chances of a cataclysmic earthquake striking the area.

Due to media saturation the potential of a Yellowstone eruption has been fodder for much discussion, since if it were to transpire it would certainly be an apocalyptic episode on a global scale. While geologists remain dubious of such an event occurring anytime soon, their fears of a major earthquake-based catastrophe have been elevated by this new data.
