Obviously what is happening in Clintonville and elsewhere in Wisconsin is supernatural.

Mystery solved........click on description here: [ link to hisz.rsoe.hu] Steve Dutch, a geologist at the University of Wisconsin-Green Bay, said the ground beneath them is solid, and that there are no known earthquake fault lines in the area. Dutch said he heard some people worrying that a sinkhole might open up and swallow homes. That can happen in areas where the ground is rich with limestone and other low-density rocks that can be dissolved by water, he said. But the rock below Clintonville is mainly solid granite that's largely impermeable. However, he speculated that water and granite could hold the key to the mystery. Granite has small cracks that water can fill, but if the underground water table falls especially low, water can seep out, leaving gaps that cause the rocks to settle and generate loud noises. "Maybe the very dry winter caused more water to be removed from the water table, either through pumping or natural flow," he said. A seismic station near Clintonville, a town of about 4,600 people about 40 miles west of Green Bay, has recorded unusual ground shaking since Sunday night. Scientists say such activity can be caused by mining and heavy truck traffic, but since there are no mines or major construction in the area, the Wisconsin Geological and Natural History Survey will take a closer look at the data.
