I took an undergraduate geology class in Worcester, and the professor told us he paid extra home insurance $$ for earthquake insurance, in the rare circumstance the fault line under Mass erupts. (It's connected to the NYC fault.)
Could have been any number of things, really. The on-and-off nature you describe leads me to believe that it was some sort of heavy equipment. Dunno what kind of construction there is on Mass Ave/Davis Sq, but a stream of trucks going in and out of a site for a while (say, if they were trucking in or out large amounts of dirt and construction debris) would create those kind of vibrations.
Or maybe it's aliens and just think too much about this kinda stuff. :)
That's cool. I guess it's one of the side effects of living as we do in an area with no meteorological drama -- you get hungry for that kind of site. :-)
