This is debatable, but the three worst earthquakes in the U.S. were likely the San Francisco earthquake of 1906, the Alaskan earthquake of 1964, and the New Madrid, Missouri earthquake, which was in the early 19th century.

The 1811-1812 New Madrid earthquakes are a rare example of large earthquakes occurring in the middle of a plate, there was no plate boundary involved.
While unlikely it is possible. Consider that in 1811 the New Madrid earthquake abruptly changed the course of one of the largest rivers in the world, the Mississippi.
Small foreshocks that precede a major earthquake can occur
The New Madrid Earthquake on February 7, 1812 is estimated to have measured 8.0 magnitude.

....
Most earthquakes occur along plate boundaries, which was not true of the New Madrid earthquakes. It was an unusual earthquake because of its location, duration and intensity for that location.
No the New Madrid Earthquake just rang the liberty bell. The earthquake's epicenter was in the boot heel of Missouri, but the earthquake was so strong that it was felt as far away as New York, Canada, and Washington D.C.
yes new Madrid
1 death
Earthquakes occur in the New Madrid seismic zone every day. Most of them are so small (magnitudes 0, 1, 2...) that they can't be felt, only recorded by an instrument. The faults in the New Madrid seismic zone are active, producing these small events all the time. If you mean Madrid, Spain, you can do an earthquake search by googling "international seismological centre".
probably the New Madrid, MO earthquake of December 1811.
bad
New Madrid Missouri
so many people die in Tokyo than new Madrid because of there a more chances there than the other one!!!peice out guys!!!
