Maine earthquake - M4.6

That's a nice-sized 'fun' earthquake.  Should be no damage, except to shopping malls on swamps.

The passive margin is interesting in that it can produce large earthquakes.  Boston rivals Christchurch in its seismic capacity, it is all on this goopy blue clay.  An M6 would rattle it good!

Update!  Now M4.0     -  Did anybody wake up?
