Beds and couches shook, chairs rattled, and chandeliers swayed. Unique experience.

I apparently managed to sleep through it, and I'm on a second floor so the feeling should have been amplified a bit. I do, however, know a number of people who did feel it. I have felt one in the past though.

I was on my back porch and I could a low growing rumble in the distance. Lasted longer than anything I've ever felt here in OKC.

Yup. Thought I was having vertigo and closed my eyes for a few and gave myself a little pep talk to snap out of it. Here I thought it worked, turns out it was just an earthquake.
Similar experience.. I thought I was having some weird inner ear problem and explained it away as my chair being a bit loose and wobbly.

I was playing basketball in KC when it happened. Didn't feel a thing. It must have happened when I was hanging on the rim after my 360 dunk. Winking

Fracking didn't cause this! Take your uneducated theory that has been proven wrong back to your tiny house with solar panels. Geez

Are you a scientist to make this claim with such certainty or are you simply regurgitating political party talking points?

I would give you the numerous studies done but I know you wouldn't believe them nor would you agree with scientific facts. People will believe whatever garbage they choose, facts aren't in the liberal playbook.
Are those the same scientists who all agree on global warming but for some reason the Conservatives all say they are to not be trusted?

Oklahoma averaged 2 earthquakes a year and in the last recent years they had thousands. Im no scientist but the guy quoted in this article is, and it seems pretty obvious Fracking absolutely is responsible for these.

We also have one of the largest fault lines & it's been that way for 100's of years.

BTW, at about 7:15 last Saturday morning my camper started rocking back & forth. I was sitting there with a cup of coffee & I was watching my coffee start moving. I thought. WTH?

FYI; just looked it up, seismic waves travel approx. @ 3 miles per second or around 11,000 mph! Took the waves about 2.5 seconds to travel 420 miles to Omaha from the epicenter in Oklahoma. Amazing.

P waves travel faster than S waves (primary and secondary) and calculating the difference between when the two different types reach you, tells you how far away the epicenter is. Get three stations and you can locate the exact location of the quake. (Its where the three circles intersect). Good stuff!

It started out well enough, but the math crashed and burned somewhere along the way.

As Cloud a Heart mentioned, there are two sets of waves generated:

P-waves:
These are the faster of the two, but are only felt by sensors. Traveling at 3 miles/second, it would make the 420 mile journey to Omaha in 140 seconds.

S-waves:
Slower, but these are the ones that cause all the shaking, damage, etc. Traveling at 1.8 miles/second, it would make the 420 mile journey to Omaha in 233 seconds.

That is a delta of 93 seconds between the two waves hitting Omaha. And this is the basis for the earthquake warning systems they have in Japan. Sensors set off an alarm when P-waves are detected and before the S-waves show up. If you are right next to the epicenter, it won't help. But this allowed people in Tokyo to have about 30 seconds warning from the Fukushima earthquake for example. I'm impressed by Japan's network, but can't understand why this isn't deployed here in places like California that are earthquake prone.

I thought also that I was having a health issue until I looked around and saw hanging plants in my 2nd floor office swinging. I thought then an earthquake, Oklahoma-Missouri fault line. Thanking the Lord I hadn't suffered a stroke, I proceeded to further thoughts of what is coming and should I evacuate my invalid wife from the house. I have asked people about their experiences and have gotten nothing but "oh, that little tremor?" Maybe they were still asleep or high already, but it certainly got my attention.

Well shoot. I must have forgot to carry the 1. Instead of 2.5 seconds, it should have been more like 2.5 minutes. My math sometimes isn't very good in the morning since I work the overnight shift, things can be a little blurry.
