Earlier this week NPR's All Things Considered program looked into the micro-quake swarm that percolated along the coast of Maine during the first week of May. On their site they have an audio version of the interview that Melissa Blocks did with Robert Marvinney, director of the Maine Geological Survey. For those who prefer the written word, a transcription of the interview is also available.
While most folks don't consider Maine prime earthquake territory, those of us who have been here for a long time know that they do happen now and again, though not usually in such quantities.
Blocks quizzed Marvinney about why such a series of quakes would occur in Maine, to which he responded, "There was a swarm like this in 2006 around Bar Harbor, another one in 1967 around the Augusta area. And because they're so rare and they're so small, we really don't have a good answer for why a spate of earthquakes will occur like this in one location."
Visit NPR's site to hear the whole interview for yourself:
