Title: underwater volcano
Post by: sg1008 on May 03, 2015, 11:02:59 AM
Here you go Rock Hound:

An underwater volcano, 300 miles off the coast of Cannon Beach, appears to be erupting.

Last fall, scientists placed a series of measuring devices on the Axial Seamount, to see if they could predict when it might erupt.

Geologist Bill Chadwick, with Oregon State University, says it appeared an eruption was imminent then last week the devices lit-up.

“All of a sudden there were thousands of tiny earthquakes that told us that magma was starting to move to the surface,” he said. “At about the same time we saw the seafloor start dropping like a rock. Over the first few days it dropped eight feet. So it’s a big event.”

 A spider crab inspects an ocean-bottom hydrophone (OBH) as it sits on the seafloor at Axial Seamount before the 2011 eruption. The OBH is a monitoring instrument designed to detect undersea earthquakes.

The movement was not sudden enough to cause a tsunami.

The team’s successful forecast was based on research showing the volcano inflates and deflates like a balloon, as magma flows in and out of its chamber.

Scientists will know for sure about the eruption after research vessels scan the area this summer.

Yep, the Axial Seamount.  The only volcano that has an almost rectangular shape.   8)   :plus:

I received a 1902 Indian Head penny in my change recently, and this got me thinking of that particular eruption.  The most catastrophic of the 20th century.  It's a perfect storm of human ignorance and stupidity that 30,000 people were incinerated by Mt. Pelee.  Put, it into the perspective of Montseratt in the 1990's, when only 19 people died in the same region and we have come a long way.   http://en.wikipedia.org/wiki/Montserrat (http://en.wikipedia.org/wiki/Montserrat)
