Back in the early sixties, I was talking to my brother-in-law who worked for an insurance company. I asked him if hiscompany sold earthquakes. He said they did but not in the northeast. He added that they were planning to sell it here in another twenty years or so, when earthquakes were scheduled to hit this part of the country. I asked how he knew that and he said insurance companies do incredible amounts of research on such things. The first one I felt in NH was in the mis seventies, right on schedule. I guess it's no mystery to those who study such things. By the way, the last one I felt was a 3.1 right under my feet last weekend.
