Well, what is interesting is that many recent EQs lay on approximately the same latitude. Look at Japan, Virginia, and now Turkey. The pattern is probably far more subtle, if there is even one...Quote from gmst:
one look at the chart you posted nitro and its clear that its not random at all. Look at the number of years in last 10 years which have been above 2sd or 3sd.......This is definitely not a tail of normal distribution. Looks more like volatility sticking together ....hahaha
More important thing is - in the last 100 years history doesnot mean that earth might be going through a geological phase (lets assume it lasts through next 5000 years), when magnitude 8 and 10 will be localized mean the earthquake distribution.
My point is just looking at last 100 years or reading scriptures for last 5000 years doesn't imply anything about the long run earthquake frequency and magnitude on Earth - in different cycles. Who knows - the extinction of dynos might have been caused by a geological period lasting over 5000 years say, when earthquakes occuring between 8 and 10 were common on EArth.

I don't know anything about this kind of science, but statistics seems like a natural thing to do...

As long as the New Madrid fault does not slip, we will be okay. If it does, goodnight to Memphis and St.Louis, and all major transport in this nation will be disrupted/destroyed. Pray that New Madrid does not slip.
