Wisconsin Mystery Booms: This Explanation Is Not It, Or, At Least, All Of It..

Wisconsin Town Figures Out Source of Mystery Booms  Newser.  Excerpts:

The mysterious booms heard in Clintonville, Wisconsin, had experts stumped—but there may be a simple explanation. "The mystery is solved. We have experienced an earthquake here in Clintonville,"
..
..explains that the fact that Clintonville's soil and granite isn't like what's normally found under towns suffering earthquakes.
And:
Portable detectors picked up a magnitude 1.5 earthquake—which can only be felt within a 5-mile radius—early Tuesday morning. The devices make their way around the country, and very few are in the state; it was a pure "fluke" that they were in the right place at the right time, adds the city official.


Not that booms don't occur with earthquakes; they do.  But not always, and usually of larger magnitude.  So maybe..  There could be an earthquake swarm in Clintonville.  Have many EQ's does the USGS think happened before the recorded EQ?  Have more sounds/booms occurred?  That equipment would still be there, or was it "Mystery solved:  Let's get the fuck outta here!"  And the seismometers are already gone?

And what of Montello?  The eyewitness reports seem to all point to more intense episodes.  Wouldn't the USGS make the effort to get some seismos just 80 miles to the south west of Clintonville if Montello's shaking harder?  Assuming seismometers are still in Clintonville, how many quakes have they recorded since?  Also, only a small quadrant of Clintonville was effected, opposed to most of Montello.  Also, according to reports from Montello, the boom events overlapped, with Clintonville starting Sunday, and Montello starting Tuesday.  How many quakes have been recorded in Montello?

Tunnels?

Rift Expansion?

Solar-triggered Skyquakes?
