The 1811–1812 New Madrid earthquakes (/ˈmædrɪd/) 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. Two additional earthquakes of similar magnitude followed in January and February 1812. They remain the most powerful earthquakes to hit the contiguous United States east of the Rocky Mountains in recorded history...
Contemporary accounts have led seismologists to estimate that these stable continental region earthquakes were felt strongly throughout much of the central and eastern United States, across an area of roughly
50,000 square miles (130,000 km2), and moderately across nearly 3 million km2 (1 million sq mi). The 1906 San Francisco earthquake, by comparison, was felt moderately over roughly 6,200 sq mi (16,000 km2)...
The three earthquakes and their major aftershocks...
Aftermath...
Due to the nature of the underlying rock mass, which contains few fractures or faults, the seismic waves generated from the earthquakes were able to travel great distances without being interrupted. Persons as far away as Canada felt the ground shaking. Intense effects were widely felt in Illinois, Arkansas, Tennessee, Kentucky and Missouri...
