I never bought the explanation that a 1.5 earthquake on Sunday would cause 3 days of "booms". I looked on the map and the USGS hasn't put a quake up for last nights activities. So what are they going to say now? I have no idea what is causing this, but I do wonder if the officials are covering it up to avoid panic.

this article says they still aren't sure what it is and that a 1.5 wouldn't likely cause a loud sound (im thinking shaking would be possible due to the type of rock in the ground??). it goes on to say that it could be movement of water underground or thermal expansion of underground pipes. maybe the 1.5 picked up by the seismograph wasn't really a true quake. anyway, they aren't set on the quake theory.

I have read that thread and keep looking back at it. With the booms happening again, I pulled up Cracking an eggshell again. So I have googled "Niagara Escarpement anomaly (unnamed faults lines)" and pulled up this:

Find complete paper here:
One fault, tentatively named the Birch Creek fault, is located approximately 3 miles north of Greenleaf, Wisconsin and is one of the most significant regional faults that cuts the Paleozoic section with about 100 feet of vertical displacement, dropped downward on the south side (Figure 3). Preliminary work suggests that this fault stretches from near Denmark, Wisconsin westward into Waupaca County.
