I live not too far from Clintonville , but lived for over a decade in central California. I can tell you for a fact that unless that 1.5 was less than forty feet under your feet you would never notice it , let alone hear it.

Interestingly you are exactly right:this particular section of Wisconsin has been relatively stable for almost 3.5 billion years. and the ground composition is very very large chunks of granite and bedrock covered by at least a couple of centuries of 'not yet weathered away silt and dust'( a perennial process that will ALWAYS have a relative "silt" coating depth in direct relation to yearly weathering and heaving).

This sets up an interesting condition: if it is a 'quake' down to a few hundred meters, even if small, the rocks in the sub soil will ring like a bell and that ringing SHOULD become longer wave propagation when it transits the rock hard substances underground into the less dense soils near the surface. just like the propagation of quake waves in the central valley in Cali ( but on a smaller propagation scale due to the relative depth and composition of materials)

if it was a slightly deeper quake the area of noticeable effect should be over a much larger surface area ( ominous indeed , but luckily not the case )

So...the most likely culprit is stress fractures occurring in "near" surface dense rock being bent or stressed to the cracking point.such a thing would produce localized near surface noise as the near speed of sound cracking was translated into 'slow time' by the soft , low density surface transition , resulting in a local boom , and vibration without much propagation .

THE very viscous fluid "shape" the sub surface rock floats on may have changed it's "level' state, from change in the earth's curvature ( possible planet expansion ) or temperature state( higher average than before in history ), which would lower it's density slightly and allow the subsurface granite to sink and flatten a bit ) .Or the the buoyancy of the near surface granite sub surface no longer is in the same 'buoyancy condition' as it has existed in for epochs.

in any event if a chunk of subsurface granite was suddenly cracked on e would expect the exact conditions that we see in this environment.

if somone has already posted something like this throw a couple of tomatoes at my noobs and move on ( I am still on page one ) ;-)

Additionally it occurs to me that this mechanism is probably quite common , geologically time-wise speaking and most probably the "pre-natal" steps in volcano creation. my guess is really long sound times ( as most of them seem to have fairly short relative periods ) would mean really long up down cracks forming ( up and down cracks would keep the sounds localized as seems to be the case ) . My guess is that the longer ( distance wise ) the crack the longer (time wise ) the sound it would make ( as sound travels at around 1100 feet per second some useful ratio may be able to determine how much sound , given the geology , equals how long of a crack ).

which leads me to another thought : is underground or sub surface 'lightning" possible? , this would also fit the known data if it is possible that solid ground can emulate the conditions of the surface. the sun has been EXTREMELY active recently , and Tesla's experiments in Colorado seem to suggest that this is at the very least theoretically possible, perhaps they are one in the same . subsurface lightning fissurieng bedrock due to near instantaneous temperature differentials ( if you have never seen glass break due to heat place an electric solding iron on a sheet of glass some time. ) . just a thought

two things of note:
after reading this post another interesting thought should be considered. the earth's magnetic field has been getting weaker, this should certainly influence "charge height" ( weaker field means higher amps closer to the center ) , dropping it closer to the center . also Earth quake lights are a known scientific would seem certain places ( like Colorado springs and other large chunks of rigid hi-content Ferris, or tribioluminecent (

This effect is called triboluminescence, which is similar to the electrical charge build-up that produces lightning, only much less grand. Triboluminescence is the emission of light resulting from something being smashed or torn.
materials ) would fulfill the parameters for the known data

After a little looking ...the cracking and fracking have interesting overlaps.
