are we supposed to see something unusual here?
That seems pretty consistent with normal earthquake activity to me.

Perhaps. I guess its the VA and UTAH ones that just stuck out to me

VA earthquake.usgs.gov...

UTAH earthquake.usgs.gov...

An honest question! because I don't know! but when there is a large EQ like this don't they normally have aftershocks quite soon after? haven't noticed any!

I wondered about that earlier - not just aftershocks, but often preshocks, before the "big one"... and that didn't happen in Chile either.

I'm sure there's a simple explanation as to why that is, but I don't know what it would be.

Chile did have a 5.1 a day before the 7.1. Is that a pre-shock?

Interesting, I counted 47 EQ in less than 24 on March 25, 2012; and it looks like it is continuing into the 26th...

Australia had a 6.1, which is extremely rare of that magnitude in Central Australia.

Hey guys you all need to take a look at this link:
earthquake.usgs.gov...
Basically its the average number of earthquakes of certain magnitudes a year
Obviously its not going to be exact, so some years there are going more, and also they will be spread out across the globe.
So its all pretty normal! You've just decided to tak notice in 2012 as the worlds meant to explode or somet. But your 9 months early :|

Well yes I am sure it's pretty normal, but the question I have in trying to understand how all the plates interact with each other, is are these lesser quakes a reaction to the large magnitude ones?

So many quakes.
So little time.
