https://en.wikipedia.org/wiki/1811–1812_New_Madrid_earthquak...
"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. 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."
I distinctly remember as a third grader in Radcliff, Kentucky doing several science and writing assignments related to earthquakes in the United States because there was all this news and speculation about New Madrid.
It's probably just the natural attentuation towards chaos in every American boy, but there was a distinct flavor of "wouldn't it be cool if ...?" to it all.
Needless to say, it was an extemely disapponting summer that followed.
Also, most people don't want to live in daylight bunkers to mitigate a risk.
In no particular order:
1. Expense
2. Flooding
3. Radon
4. No one aspires to be a basement dweller.
And when they do occur, the area they effect is very small.
You also don't get days of build-up like a hurricane, it's only around 10-15 minutes to go from "a storm that might make tornados (like many are)" to "one is likely to appear at X" to "hopefully you're already sheltered, it's here". Hunkering down has to be done rapidly, which is stressful and memorable, even if nothing happens to you.
I live by the Great Lakes: we don’t have earthquakes or hurricanes or tornadoes.
Plus I don't have to worry about an aquifer running dry.
