New Subduction Zone Forming

New 'Embryonic' Subduction Zone Found | Geology

Peace,

That's really cool. Guess this subduction zone will close faster than the spread motion from the mid Atlantic Ridge? Hmm, could end up looking like Juan de Fuca/Cocos/Nazca subduction zones off the west of the Americas. Not really a good thing though, a subduction earthquake and tsunami in the Atlantic would be much worse than the Pacific basin since the same warning systems are not in place. It does make a lot of sense with respect to the Lisbon quake. All the estimates I've seen for it are 8.5 - 9.0 + huge tsunami. Pretty much limits it to subduction movement.


EDIT: Also makes me wonder if some of the other large intraplate earthquakes (New Madrid, Ontario/Quebec border region) could be from the birth of a new fault system. I've heard other theories about these areas, everything from the land rebounding after glacial compression to a weak spot in the crust from an attempted split (plate abortion?) in the past. Not sure if there has ever been a total conclusion to why these large quakes have occurred so far from the known plate boundaries. Even if it wasn't something as major as a new subduction zone, even the birth of a deep thrust fault, or transform system could be disastrous in these areas if an unexpected ~7.0 quake suddenly occurred.

Cant see anything, says im not invited or something.

Weird, it works for me still. Here is the article for those who can't access the page:

I call dibs on new Atlantis beachfront real estate :tinfoil: Heard about the ibirian movement a while back. This is pretty interesting :thinking:

Good find Daguin :beer:
