This entire cliff at Snake River Plain would have been formed as a result of a super eruption
 
Eruptions at Snake River Plain in Idaho were “significantly larger” than geologists had previously thought.
 
Scientists from the University of Leicester discovered there were a staggering 12 massive eruptions over the course of four million years, beginning 12 million years ago. 
 
The massive eruptions helped to form the 100 kilometre-wide Snake River Basin, with one of the most powerful eruptions occurring 8.1 million years ago. The eruption's volume exceeded 1,900 km3 and created a 1.3km thick caldera.volcano, growth, supervolcanoes

Furthermore, the Snake River Plain is situated on the Yellowstone Hotspot track, a region which spans from Nevada, through Oregon and Idaho and then to Wyoming where Yellowstone Volcano is located.

MASSIVE UNDERWATER VOLCANO ERUPTING 300 MILES OFF THE OREGON COAST - Activity by the Axial Seamount volcano has caused numerous EARTHQUAKES and the seafloor has dropped 8 feet, signaling magma movement

Is Axial Seamount erupting? Seafloor off the coast of Oregon has dropped 8 FEET due to movement in the 'wired' underwater volcano.

  • Geologists previously predicted Axial Seamount would erupt this year
  • For more than a week the region has experienced thousands of tiny quakes
  • Seafloor has also reportedly dropped by almost 8ft (2.4 metres)
  • Both are said to be a sign of magma moving from beneath the summit


  • Last year, researchers connected monitoring equipment to an undersea cable that allowed them to gather live data on the volcano (location marked), whose peak is about 4,900 feet (1,500meters) below the ocean surface
