In California and the western U.S. States, earthquake faults can be hundreds of miles long and be visible on the surface of the earth. In the central U.S. however, faults are buried deep underground and are generally categorized as “seismic zones”, or areas where many smaller faults are clustered together to produce seismic activity. While some zones, such as the New Madrid Seismic Zone, may be more widely known, others such as the East Tennessee and Central Virginia Seismic Zones can also produce damaging earthquakes at any time.
