Predicting When They'll Blow

If the world ends, will it be water (again) or fire? When volcanoes erupt, the devastation is short-lived, but violent. Magma creeps up through a crack in the Earth's crust and mixes with water, setting off a series of explosions--as many as a few each hour for several weeks. When the action stops, a crater-topped, rock-filled fracture called a diatreme is left behind.

If volcanologists could understand how to predict these volcanoes, they could not only save lives, they could find DIAMONDS.

Diatremes are sometimes formed by a type of molten rock which has the deepest origins of all magmas on Earth. When this magma cools, it leaves behind rocks dense in crystals, sometimes holding diamonds.

In the Huffington Post and on, Megan Gannon quotes geologist Greg Valentine as saying, "Previously it was thought that those explosions started at very shallow levels and got progressively deeper, but that model didn't match with what geologists were finding at volcanic sites.

"These volcanoes can send ash deposits into populated areas. They could easily produce the same effects that the one in Iceland did when it disrupted air travel, so what we're trying to do is understand the way they behave."

Meanwhile, a Japanese researcher says it's theoretically possible that the we could have an earthquake with a magnitude of 10 (the highest that can be recorded). No magnitude 10 earthquake has ever been observed--the most powerful quake ever recorded was a magnitude 9.5 in Chile in 1960.

A magnitude 10 quake would likely cause ground motions for up to an hour, with tsunamis continuing for several days while the shaking was still going on.

The Japan Times quotes Toru Matsuzawa as saying, "The estimate does not mean that a magnitude 10 quake will inevitably happen. If it happens, it would take place around once every 10,000 years."

We want to deliver a small warning to all our readers and listeners: If we don't get more support from you, it won't take a volcano to finish us off, and it will happen FAST: We will be nothing more than a memory in the future.

"Magma creeps up through a crack in the Earth's crust and mixes with water, setting off a series of explosions--as many as a few each hour for several weeks."

Could this be what's happening underground some of these populated areas where people are hearing the loud booms (?) which are sometimes accompanied by shaking of the ground as well (as in Wisconsin).

Perhaps as our axis of rotation shifts. new cracks in the borderland are thrusting more magma upwards. It may also take unusual (and perhaps novel) routes due to unintended consequences of mining and drilling deep underground. imo, If the booms have a natural cause, this sure sounds like it could be one.

Cayce predicted earthquakes of magnitude 12 at the time of the pole shift. He predicted inundation of both east and west coasts (east coast first) as a precurser to the changes. He thought many of his pre-poleshift earthchanges predictions wld come to pass in the 80s (such as the great floods). Timing is tricky when making predictions (as Ed Dames will attest to). Not so sure that earthMother wants to be so predictable . . . maybe we shld just create a civilization that knows how to rockin/roll w/her.
