breaking: wisconsin strange sounds solved
they are reporting on the news here that it has been solved. according to a bunch of scientists, clintonville is experiencing cryoseism as a result of a very early spring here:
A cryoseism, also known as a frost quake[1][2], may be caused by a sudden cracking action in frozen soil or rock saturated with water or ice.[3] As water seeps down into the rock, it freezes and expands, putting stress on surrounding rock. This builds up until it is relieved explosively in a cryoseism.[4] Another form of cryoseism known as an ice quake, is a non-tectonic seismic event caused by sudden glacial movements, sometimes due to the formation of a thin veneer of liquid water under a glacier from surface melting. Usually, a glacier would stick to the rough bedrock, but the hydraulic pressure acts as a lubricant, allowing it to slide up to many metres at once.[5][6] This type of cryoseism can last for tens of minutes.[7] As the requirements for cryoseisms to occur are not yet defined, their prediction is still not possible and constitute a significant factor in structural design and engineering.[3] Links have been made between global warming and the frequency of cryoseisms.[7]
apparently the effects in clintonville are exaggerated even furhter, as the town lies right on top of a large, underground, pure granite shelf. the water seepage is coming from the lake next to the town, they say.
fwiw, i still think it's giant robots from mars waking up.
