they can cause damage in Alabama, Arkansas, Illinois, Indiana, Kentucky, Mississippi, and Tennessee. About every 18 month earthquake that causes damage in the area, usually cracks in sheetrock is the extent of the damage. The largest quakes were thought to of occurred in 1811- 1812 estimat magnitude. They changed the landscape in the bootheel causing landslides, knocking down trees, and disrupting the river. Church bells were ringing by the quake as fa D.C. (Resources, N.D. ) I have been in the area many times and never felt anything. I do hear about them regularly on the local radio stations which, is interesting to me. wonder if they could become more severe as they were in the past. References Resources, M. D. (N.D. ).

I had always thought earthquakes just occurred at plate boundaries. I looked up some information on mid-continent earthquakes and found out they’re different than earthquakes that occur at plate boundaries. Earthquakes that occur at plate boundaries usually occur at the sam because obvious it is where the two plates meet and are grinding past each other. Mid- continent earthquakes work by interconnected faults and the earthquakes never occur at the same fau earthquake hits at a fault, the stress is then transferred to another fault. I found an article on Livescience.com which explains mid-continent earthquakes and how it seems much less is known a compared to plate boundary earthquakes.

I have been through there on several occasions, so I suppose my timing has just been right to miss any m amazing how far we have been able to come in the identification of seismic activity, and are able to identify all the major areas where the activity can and/or will occur. That had to have been an ominous feeling to hear church bells ringing because of an earthquake. It almost sounds like something you would see in a movie or read in a book.
