une 17, 2013 — A new subduction zone forming off the coast of Portugal heralds the beginning of a cycle that will see the Atlantic Ocean close as continental Europe moves closer to America. Share This:
143 Published in Geology, new research led by Monash University geologists has detected the first evidence that a passive margin in the Atlantic ocean is becoming active. Subduction zones, such as the one beginning near Iberia, are areas where one of the tectonic plates that cover Earth's surface dives beneath another plate into the mantle -- the layer just below the crust. Lead author Dr João Duarte, from the School of Geosciences said the team mapped the ocean floor and found it was beginning to fracture, indicating tectonic activity around the apparently passive South West Iberia plate margin. "What we have detected is the very beginnings of an active margin -- it's like an embryonic subduction zone," Dr Duarte said. "Significant earthquake activity, including the 1755 quake which devastated Lisbon, indicated that there might be convergent tectonic movement in the area. For the first time, we have been able to provide not only evidences that this is indeed the case, but also a consistent driving mechanism." The incipient subduction in the Iberian zone could signal the start of a new phase of the Wilson Cycle -- where plate movements break up supercontinents, like Pangaea, and open oceans, stabilise and then form new subduction zones which close the oceans and bring the scattered continents back together.

The Iberian subduction will gradually pull Iberia towards the United States over approximately 220 million years."I don't want no damn white Eur-o-pee-ans comin' over and messin' with what Barack's gettin' done here! For the first time, I'm proud of this country!"

Doesn’t that also mean that there is another plate, probably in the Pacific, that is being pulled apart??
Maybe off the west coast??

As Global Warming loses its cachet and is discredited will this be the new sky-is-falling hysteria? It would be an interesting one, and based on something that is probably really true and will severely affect coastal environment in only a few hundred million years. If we don't prepare it will suddenly be upon us and we will all get crushed!

Better hang a few boat bumpers off the coast.
