Is a supervolcano brewing beneath
Mount St. Helens?

 __________________




Jun 09 - Beneath Mount St. Helens lies “what may be an extraordinarily large zone of semi-molten rock, which would be capable of feeding a giant eruption.”

Magnetotelluric sensors around Mount St Helens reveal a column of conductive material extending downward from the volcano and then connecting to a much bigger zone of conductive material, which scientists believe is magma.

This larger zone extends to beneath Mount Rainier about 40 miles to the northeast, and to Mount Adams about 30 miles to the east.

“If the structure beneath the three volcanoes is indeed a vast bubble of partially molten rock,” said an article today in New Scientist, “it would be comparable in size to the biggest magma chambers ever discovered, such as the one below Yellowstone National Park.”

“These enormous eruptions can spew enough sunlight-blocking ash into the atmosphere to cool the climate by several degrees Celsius.”

          I think we’ll eventually find that many of the world’s volcanoes are
          interconnected in this manner. But whether they are or not, if the
          Yellowstone supervolcano should erupt – if any supervolcano should
          erupt, for that matter – we’d descend an ice age within months …
          if not weeks
. (That's what cooling the climate "by several degrees
          Celsius" would do.)
