You are right. It is extremely unusual to be aware of even a small earthquake in the Boston, Ma. area. I was a lifelong resident of MA. until we moved to KY fourteen years ago. If I recall correctly, we did feel a very minor tremor there about 16 years ago, with the epicenter being in NY state. It makes you wonder what on earth is going on with these odd occurrences.Me too. I just talked to a family member this afternoon who's in Boston on business and they felt that earthquake there. Said she'd felt stronger ones in her travels, but it was a bit unnerving to her at any rate. Specially being in a high rise motel in the heart of downtown Boston..
That New Madrid Fault really concerns me, that much I will admit. If that thing shifts like it did in the 1800's, well.. We all know how much devastation would occur and there would be no escape.. Not to mention, the Wolf Creek Dam scenario..
I have been keeping track of the animal die-offs, earthquakes, and volcanic eruptions, and this seems to be a period of disruption for planet earth. Some of this activity may be related to heightened solar activity. We are within a two year span of solar max., through 2013. So the activity (solar flares, solar wind, etc.) will peak in about another year.
