Interesting to see this. I heard booms or rumbles last summer on more than one occasion. No explanation for them. I live in NW AR.
Now, what is coincidental, or not, is I just received a letter from my insurance company regarding EARTHQUAKE insurance. I have been their customer for over twenty years and this is the first such letter I have ever received. It mentioned something about some law passed in 99 that they are complying with and the fact that I don't presently have EQ insurance and that my policy doesn't allow the addition of EQ insurance and that if I don't want EQ insurance I have to send back the enclosed letter denying coverage. Contact my insurance rep, blah, blah, blah.
I'm a bit confused. My policy won't let me add it, but I have to decline it if I dont want it.
I'm wondering if any other people or states are getting such notices?
