Wow. God hates the Pacific coast. But then theirs that random red blob in the middle of the country. Seems an odd place to have major quakes.

The Pacific coast isn't surprising on account of the famous "Ring of Fire" that surrounds the entire Pacific Ocean. It's a ring of heavy tectonic and volcanic activity. As for the blob in the middle of the country, that's the New Madrid Fault zone. Back in 1811 and 1812 there was a series of massive earthquakes there, resulting in some stuff that would have seen Biblical at the time, like quicksand geysers erupting from the ground and the Mississippi River flowing backwards. It rung church bells all the way over in New York City. |

I didn't know about the New Madrid stuff. Everyone thinks of California when they think of quakes. What's the other red spot at the corner of Wyoming? There's also a yellow spot by itself in South Carolina.

There's also a yellow spot by itself in South Carolina. I don't know about the South Carolina one but the Wyoming spot is the Yellowstone supervolcano. It's not like the regular volcanoes you think of where it forms a mountain with an opening on top. Yellowstone is a supervolcano that does kinda the opposite. There's a giant lake of magma underground and when it erupts it empties a lot of that magma chamber and the ground above collapses into the void,leaving a huge caldera. It's had super eruptions periodically in the past, which haven't been in the same spot on the surface due to continental drift, so if you fly above the region there's a visible scar across the landscape where there's depression instead of mountains. It almost looks like the finger of God went through erasing mountains. |

Huh. I had no idea so many places were so active.

I think most people are unaware of faults everywhere or that basically anywhere can potentially have earthquakes, and without it being Biblical.

Yes. Not everywhere has them frequently, and they're usually not strong enough to be felt without seismometers, but they're there. I couldn't find figures for numbers of faults per state so I tried counting them on maps of different states. I started with my own and then looked at adjacent states. It's hard to keep them all straight since the lines crisscross the maps. I don't like for anyone to give away too much personal information so I won't say which state I specifically live in but I looked at West Virginia, Ohio, Pennsylvania, Kentucky, Tennessee, and Virginia before stopping and they look to typically have a couple or three dozen apiece. Mind you, they're often small, like maybe tens of miles in length, but they're all over. Some of those maps also had dots showing different earthquakes in those states over the past couple centuries and sometimes those quakes aren't near any of the fault lines on the maps because quakes don't even have to take place near a fault line. They're a consequence of stress in rock and rock can be stressed anywhere.
