I just noticed this on the USGS site.

Wow, you'd thing that even at 1700+ miles away I would of at least felt a little shaking.....5.2 is enough to rattle the crystal glasses.....

Thanks for the heads up !

Or that I'd have felt the 2.5 in GA at least; being in the ft Bragg area. Not very knowledgeable about earthquakes though. How far away would one feel these?

it seems to be dead center atlantic ocean i read somewhere that the ridge could produce massive tsunami by underwater landslide

I don't know how far away this will be felt. How big does one have to be to generate a tsunami? The way things are going, something like that perks my ears. It could be a total fluke, or the start of something else.

Maybe we could watch for volcanic changes in Iceland or something.

It all depends on the density of the ridge. I was under the impression that the North Atlantic ridge was solid rock...I might be wrong but....5.2 is quick the shake, isn't it?

area affected depends on region if your say in the rockies area would be small but in a place like mid west america it would be much bigger area of affect

I'm on my mobile at the moment so can't post data from before but I'm pretty sure I've seen plenty of 5.1-5.5 earthquakes on the Mid Atlantic ridge, highest in-fact is 5.6.

It's capable of a large quake, but 5.2 is nothing to worry about.

Found this 6.9 there in 08' after a quick search.

Dont' know, but if there was a landslide undersea or is was a single "pop" wouldn't that generate some kind of pressure wave in the water?

Cool. I hope it's nothing. I have friends in Virginia Beach and things like that scare me. We're already flooding here in the midwest...the last thing we need here in the US is a tsunami on the east coast.

Guys, a 5.2 in this area isn't worth paying too much attention to.

As to how far away you'd feel it; you can go to that link I provided and click on the map tabs. For an earthquake near a populated area that gets felt reports, there will be shake maps that show the intensity levels.

A 5.2 is only a moderate quake. It was a bit shallow, but being out in the ocean,it wouldn't have been felt anywhere. Typically it takes over 6.0 to pose any tsunami threat and it also depends on the type of fault (movement involved) and shape of the ocean floor. (it is all about water displacement)

Even if this had been on land, it wouldn't have been felt that far away. Probably not even a hundred miles. Again though, depends on the type of land it happens in. Rock vs sand, etc.

I'm in miami and i'm always on the lookout.
But there's no tsunami warning or anything like that from waht i can tell.
probably just a quake and nothing else.

Atlantis rising?

You never know... it's in the "general vicinity" of where Atlantis is fabled to have been, according to most academics.

I'll keep my fingers crossed. I'd totally relocate there if it did rise. lol

Thanks. That pretty much covers it for me. Thanks to all the rest of you guys too for adding to my, addmitted, limited knowledge in this area.
