Theory on the earthquake of today

Not sure how many of you have heard about it, but it was a 4.5 and it happened on Chicago. I looked at the dates and I noticed something. 1881, 1912, 1972, 2004

31, 60, 32

So I think that this is on a chain of events that adds 1 to the chain

i.e. 31, 60, 32, 61, 33, etc.

So, if I'm right, the next earthquake up here will be in 2065..

not sure many of you care, but I thought it was interesting.

That is a really really really stupid coincidence.

Chicago...strange place for an earthquake.

lol that is a pretty.... not so good theory, but Chicago is indeed a strange place for an earthquake. I never knew that they had ever had one there.

meh, it may be a bullshit theory, but I thought I'd try something.

I don't think 4 earthquakes themselves are substantial enough evidence to pull a theory out like that.

yeah, I know...but I'm bored :/

Or they could be getting closer together...

31 60 32 59 33 58

Or they could be alternating 60 with 1 and doing random numbers in the 30's.

31 60 32 1 37 60 34 1

Or they could be not related at all.

Just thought I'd throw in some other theories.

Well, arithmetics can be applied to just about any situation like this, it's just a matter of how complicated you want to make the number sequence.
