Magnetic potential map of the Reelfoot Rift. The New Madrid Seismic Zone (NMSZ), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
Charleston earthquake or 1886. Charleston earthquake or 1886. An estimated $23 million ($186.51 million in 2023) in damage was caused by one of the great earthquakes in United States history in 1886. Charleston and nearby cities suffered most of the damage, although points as far as 160 kilometers (100 mi) away were strongly shaken.

New Madrid fault and earthquake-prone region considered at high risk today. The 1811–1812 New Madrid earthquakes were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day.
However, buried under several states to the south-southwest of Michigan lies the New Madrid fault line, extending 120 miles from southeast Missouri into northeastern Arkansas. But in the event of ...
The Brevard Fault Zone is a 700-km [1] long and several km-wide thrust fault that extends from the North Carolina-Virginia border, runs through the north metro Atlanta area, and ends near Montgomery, Alabama. It is an important Paleozoic era feature in the uplift of the Appalachian Mountains.
The 1886 Charleston earthquake in South Carolina occurred about 9:50 p.m. local time August 31. It caused 60 deaths and $5–6 million ($186.51 million in 2023) in damage to 2,000 buildings in the Southeastern United States. It is one of the most powerful and damaging earthquakes to hit the East Coast of the United States.
