Ancient “Volcano” at Washington State!
posted in Amazing Facts, Devastation, Latest News |
An ancient “supervolcano” is present in what is now being called “Washington State” it gave out steam and billowed ash in enormous amounts. The blow-up happened in two major bursts that occurred around 3.7 million years ago in the northern Cascade Range, causing the flow of hot gas that belched out around 33 cubic miles of ash.
This according to the researchers at Western Washington University is not the first and the last eruption to occur there. The blasts that occurred could have killed all the life that existed several miles further. It might have also collected large amounts of ash around the down hill area.
When this volcano occurred, the crack widened, and made the ground on one side drop like a trap door swinging down. This section of earth fell more than 3,000 feet (1,000 meters).The second eruption occurred around a hundred thousand years later, when the upper end of the trap door dropped, forming a rectangular crater measuring 5 miles by 2.5 miles.
The two eruptions described involved a total of around 30 cubic miles magma “in a period of just a day or two.Ever since, the site has been silent, as volcanic activity has shifted 15 miles (25 kilometers) southwest, to the present location of 10,778-foot (3,285-meter) Mount Baker, near the city of Bellingham.
No one can predict about Mount Baker, or another peak in the Cascades, they might someday produce a huge eruption.
