That would be Lake ArQuakeia wouldn't it?

OGS is showing preliminary 4.8

That ties at #5 as the biggest quake in recorded Oklahoma history.

Now we get to see if there are going to any aftershocks or if this was a foreshock.

[zookeeper]

Which is most likely more accurate? OGS or USGS?

Out in Surrey Hills, it felt like a wave going through the house. You could actually hear and feel the movement from one end of the house to the other. It seemed to last for quite a while. And after it stopped here, I could hear it moving away from us. Quite an experience. I remember feeling the 5.0 a few years ago, but it was more just a loud boom and overall shaking for a second or two. This was more a wave action. Two very different experiences.

I think there are slightly different ways they calculate the magnitude. It's been a few years since I've read about it.

Yikes! A pleasant thought.

Actually (and unfortunately) it could be both as those two things are not mutually exclusive.

[Cocaine]

They'll revise it later any way.

Imagine, during tomorrow's game, that right after KD slams down a thunderous dunk, a 5.5 quake unleashes.

The Pacers would probably just give up at that point.

Yukong,
It was a loud sound, I'm not sure it sounded like an explosion, a little different sound but very loud. My first thought was an explosion but in about a second it was obviously an earthquake. The difference between your experience and mine is distance. I live 9 miles Northwest of Jones and the epicenter was 4.5 miles Northwest of Jones.

We're at Twin Peaks watching Bedlam. It shook dust off of all the high wall decorations, neon signs and rattled all the bottles at the bar.

My daughter lives in Jones and said it was a good thing she was already down on the floor wrapping Christmas presents instead of standing up.

Ljbab,
Your daughter and I had the same experience, the epicenter was right between us. I'm glad I was sitting down, with my current health (and age), I'm not very steady. I think I would have hit the floor for sure!

I didn't feel or hear the earthquake while watching Bedlam on TV in Stillwater. Some from Stillwater have reported something, though. BEAT OU!

[CaptDave]

In North OKC/West Edmond, I heard the crack, followed by a rumble to the east, then felt the shaking. I have never experienced the stages of an earthquake like that before.

[SoonerDave]

Definitely felt it here in SW OKC , but not nearly as strong as others. Based on the posts here, it sounds like the more you go west and north, the stronger it was.

[venture]

Someone just tweeted that yes...OGS and USGS are measuring the magnitude differently, so that is why there will usually be a discrepancy.

[Praedura]

Snow...ice...arctic temps...earthquakes...

Yawn. A typical fall day.

[ctchandler]

I just felt a mild "after shock".
