I felt today’s DC earthquake in Cleveland. It was just two little jolts. But the Midwest is not immune from major earthquakes. In 1811/1812, four magnitude 7~8 earthquakes hit New Madrid in Missouri. Two hundred years is but a heartbeat in geologic time. More such earthquakes can hit without warning. California is well prepared for such earthquakes, having experienced so many over the last century.
Midwest cities like Cleveland and Detroit are run by corrupt Democrat machines. Building codes may exist but they are not enforced. Bribery is rampant. So, when the big one hits such a city, how well will it do? Will buildings collapse because they weren’t built to code? Is the code stringent enough to protect against a magnitude 8 earthquake? I hope I never find out.
