Strange Earthquake in Atlantic Ocean

Just saw THIS quake in the "ridge" of the Atlantic, map seems odd, I guess that's the continental edge of land. I don't know much about this. Anyone follow earthquakes daily? Can you tell me should these be common?

I don't knowabout common but there not unusual. The Mid-Atlantic Ridge is the point between the NA plate and the Eurasian/ African plates so quakes would be expected to occur.

Check out this it shows where those plates meet.

....nice link. Shows a lot. That plate seems to fit exactly where the
quake was, probably pretty common there. Proves something about
the "big one" in CA, that plate spans the Pacific rim where a lot of
activity seems to happen, well, happens. Other side is the entire
coast of CA, I can't picture how bad that could be should you research
some recent "big ones" they literally move the coasts. Interesting about
the amount in the mid east, China -- looking thru an Almanac it shows tens
of thousands of deaths over only a couple of decades to earthquakes. Some-
thing like that hits the US, it'd be the tragedy of people's lifetimes, obviously.

Definitely not uncommon.... in my few years of tracking quakes, I've seen many in the North Atlantic Ridge Area. I do think it's an interesting area to watch however because a massive quake there could be the trigger for an East Coast tsunami..

All along the tectonic plate boundaries, the Earth's crust is pushed downward toward the mantle where it melts into magma...and the North Atlantic ridge is a very active portion of the global ridge line where new magma emerges to create new crust on the ocean floor and on a few land masses.

It is basically a solid-land recycling machine; much like earthworms, on the microcosmic level, continually turn over and renew the soil, but on a much larger scale.

Here is a link from USGS which is full of information.

activity certainly has been interesting in the east coast. yesterday there was a 2.5 mag in Littleton, New Hampshire at around 1 p.m.

a VERY rare event
