An unsuspected 5.2 earthquake hit the Midwest this Friday that was felt from Kansas and than all the way to Georgia. Geophysicists beleive that the aftershocks of the earthquake will be felt for a few months and that there may just be another big one coming in its wake.
The quake occurred on a northern extension of the New Madrid fault, about 6 miles north of Mt. Carmel, Ill. The New Madrid fault was responsible for devastating quakes in the Mississippi Valley in 1811 and 1812. So the Friday quake and its aftershocks likely are raising the blood pressure of some residents and scientists.
