9297 Earthquakes since 4 sept 2010.

We just got hit by a swam of earthquakes today. Geologist are saying this is a very rare event, with this amount of plate tectonic activity. If you want to know more:

definitely a seismic active area. I'm glad it wasn't worse.

wow - very interesting!
those shown were 6.0 and larger.
It's pretty apparent that the west coast of the USA is very quiet. maybe too quiet.

Thanks for that jinro. That region from NZ up to Japan is getting hammered.

Chile and Indonesia weren't doing so well either.

And my speakers almost exploded when March 3 came up.

It's the earthquakes 6 and under that are getting to people around here, I can tell you.

These things happen when you live on the ring of fire.

Correlli · #9 12-23-2011, 12:21 AM

the ring of fire may have to be evacuated.

That happens after every time I have Indian food.

Is it not better to have a lot of smaller quakes to release energy than to let it build up to a big one?

This situation is a bit different. We've been getting big earthquakes and swams of aftershocks. Been getting aftershocks all night. People have had enough and are leaving.

Sounds rational to me.

We are at war, with earth. That's what it feels like.

A lot of it depends on where you are. An earthquake at the San Andreas fault will net so much damage in a certain area, while the same magnitude earthquake at the New Madrid fault will cause much more damage over a much greater area. I think it has something to do with the type of soil or bedrock or something.

I'm wondering if a volcano nearby is going to blow its top. We've got six active volcanos.

Correlli · #18 12-23-2011, 07:33 PM

Or... is there a volcano forming under the city?

Imagine that.

Amount of damage from earthquakes also depends on the build quality of the structures in the area of the quake. So in addition to the magnitude of the quake, how far beneath the surface the quake is centered, and what types of material the Earth's crust in the area is made from, you have to consider whether the buildings in the area affected by the quake are built up to earthquake standards. Look at how bad the damage has been in areas like Haiti, Turkey, and China where the schools, apartment buildings, etc. were not up to standards, for whatever reason. While a lot of the more current quakes in California and Japan have not had as much damage from quakes - except to older buildings that were built at times before construction standards including earthquake codes. Yep, if - when - the New Madrid fault lets loose again, there will be a lot more damage to buildings than would be caused by a similar sized quake on the West Coast, not only due to the structure of the Earth's crust, but also because many of the buildings in the area were not built to earthquake standards. The point five (or therabouts) earthquake we had on the East Coast not only created more of a sensation here because we don't get quakes very often, but if things had been built with quakes in mind, what damage there was probably would not have occurred. If we ever get a point seven or higher earthquake on the East Coast, you'll probably see far more damage here than you did when point seven or larger earthquakes took place on the West Coast.

One of my ex girlfriends had been living/working in Christchurch for a few years. She recently relocated to Abu Dhabi, not because of the quakes, but it helped her make the choice to go.

I hope the plates settle for your area soon and without much more fuss.
