” This was the first of three magnitude-8 earthquakes and thousands of aftershocks to rock the region that winter. “
“that winter” was 1811-12 (still not out of the Little Ice Age which went to 1850) -
The place, Mississppi Valley.
It rang church bells - in BOSTON! - and was felt in Canada.
They say it will happen again. “Some scientists claim that the so-called Big One will not happen on the West Coast at all. Rather, a surprising number of them argue that the next sizable shake might occur along the New Madrid Fault, probably by the year 2010”

Non-subduction zone quakes to me are more fascinating.
Did you feel this one?
