"...at first I thought it was the Madrid Fault Earthquake."

The New Madrid fault zone produced the largest earthquake in the history of the US. In 1811-12, I believe it was.

The New Madrid fault zone produced the largest earthquake in the history of the US. In 1811-12, I believe it was.

The 1964 Alaskan quake was much, much larger and per recent scholarship, none of the New Madrid quakes were likely larger than the 1906 San Franscico Earthquake, the 1857 San Andreas quake, or the Owens Valley earthquake.
