Normally, such tiny quakes would not be felt because the energy produced would be absorbed by the ground. This isn't the case in Wisconsin, where the ground is considered by geophysicists to be "very consolidated", which means that there is a lack of fault lines. A series of minor earthquakes in Ohio which took place earlier this year were nearly identical to the Wisconsin quakes. Some have suggested that the natural gas drilling process known as hydrau…
