Late this morning, we experienced a magnitude 3.8 earthquake. The epicenter was SE of York, Maine, near Boon Island, roughly 66 miles from here as the crow flies. At first, I thought it was a slab of snow sliding off the roof, but I could not see any evidence of that. Then I thought it might be a mis-balanced load of laundry in the washing machine. Not until I checked my e-mail to see that neighbors had already identified the event as an earthquake did I make the connection. To be fair, this was a very tiny quake the size of which occurs 500,000 times a year. Even so, it is quite a rare thing to experience living in our neck of the woods.
