San Andreas Fault Line: Spanning across the state of California, from Cape Mendocino to the Mexican border, the San Andreas fault line divides the state in two halves. Running parallel to the coast of the United States, San Andreas fault is prone to a number of earthquakes, thus making this region quite active in terms of seismic movements. 4 with a magnitude about/over 6.
New Madrid Fault Line: The New Madrid fault line has recorded over 4000 earthquakes of various scales over the last four decades. Also referred to as the New Madrid Seismic Zone, this region is one of the most vulnerable region in the United States. Earthquakes in this region directly affect a range of states including Illinois, Missouri, Tennessee, Indiana etc. 4 with a magnitude over 7.
Rampo Fault Line: The Rampo fault line runs over a distance of 187 miles, between the Appalachian Mountains and the Piedmont areas. Earthquakes in this fault line can have devastating effects on states like New York, New Jersey, and Pennsylvania. 5.
Ridgefield Fault Line: One of the latest addition to the names of fault lines in the United States is the Ridgefield fault line. It is believed that the Ridgefield fault line was formed around 250 million years ago. An Earthquake in this zone can result in severe damage to Connecticut, and the surrounding regions. 5.
