Earthquakes are usually over in a couple of seconds. At least the one I was in lasted about 5 seconds but it felt like forever.
There is a fault line in Kansas. And there also is the New Madrid Fault in Missouri and Illinois. New Madrid was very active in the 1800s.
That was a wild ride I had in 2011. GF and I were sitting on the couch. All of a sudden things start moving around. I'm thinking where did this instant high wind come from? But when I took a good look out the front door, my maple tree was undisturbed. Instantly, I realize it is my house (small 2 bedroom) rolling around like it is small boat at sea in high winds.
It was over in 5-10 seconds, or so. It happened fast and was over just as fast; There was no time to get scared GF used to live in Cali and experienced earthquakes. In a calm voice she said, "We just had an earthquake." I just sat there in dumbfounded amazement.
I still have 3 cracks in my drywall that are hidden by furniture.
That was my first earthquake. But it was not my last. I suppose I experienced anther 10-15 quakes over the next 3-4 years. But none of the others matched the intensity on Number 1. My GF's plate glass window softly rattled for about 3 minutes one night;That was strange;I could not feel a thing.
Source of the quakes: This is my home. All my life. I never knew an earthquake and now they start happening with concerning regularity.
There is an oil drilling company in Oklahoma that, with the Oklahoma Interior Secretary's blessing, started doing deep well injection of drilling waste water. The problem is that pumping all of that water under pressure was starting to act like lubricant flowing between surfaces of the underground. This caused the different surfaces to move around.
There were damaged buildings in areas. Some people had their houses destroyed. But they did not have earthquake insurance. Around here ,you insure for floods, hail, and tornadoes; Not quakes.
Once the politics was sorted and the oil driller was not allowed to continue with deep water injections the quakes slowly went away.
