My migraine aura's and their correlation to earthquakes.

I tend to get migraine type aura's that obscure my vision before migraines, but then if I don't get a migraine after the aura, without taking meds, I can say that its earthquake related. Well about 2 hours ago (its 2:33pm mst now for me), I got that aura, and I waited, and it intensified and got worse and was not accompanied by any head pain. So now it is gone, and there is no migraine, I'm glad, but this also likely means a big earthquake has or will happen again soon. at least a 5.5-6.0. Or maybe lower if it happens to be really close to me like California, or Wyoming, that could be a 4.5-5.0.
