We've had over 50 earthquakes here in central Oklahoma this year. They've all been 3.1 or lower, but that's an astonishing number, and a lot of them are being felt by quite a few people. I've felt two of them. To a girl who grew up in Oklahoma, earth tremors are not something to which you're accustomed. Our Earth is living, breathing, and changing. It is alive.
It only lasted one second, but the first tremor I felt I didn't even know was a tremor. I thought a plane had flown low overheard to Tinker AFB. I felt so stupid when I read there'd been an earthquake.
I hope this isn't creeping toward the New Madrid fault. It's quite a bit more populated than it was in 1811 and 1812. Not exactly filled with buildings constructed to earthquake code, either.
