2014 Oklahoma Earthquake Discussion

[Bunty]

In Stillwater, for the one shortly after 11am, my house felt it more than I did. The house made a creaking noise for a second. I hardly sensed any shaking or heard thunder in the distance. The seismogram doesn't seem to look like it was one of those baby, under 3.0 quakes. We'll see.

OGS Earthquakes ‏@OKearthquakes 21s
Magnitude 4.4 at 2014-04-07 11:03:03.930000 (CDT) 5.1 miles SSW of Coyle; 35.890,-97.273,z=5.2km

This is going to put the quake in the same area as the 4.2 yesterday.

[Bunty]

Oh, dang! This one at 11:38 am came with a rather loud distant thundering noise this time. It was certainly more startling than the previous one. I'm glad it only lasted about a second.

So... here's a question... why is the Oklahoma Geological Survey earthquake rating typically significantly higher than the USGS earthquake rating? Is OGS looking for more publicity with better attention-grabbing headlines that the local media then likes to trumpet over the USGS number(s)?

Case in point:

I believe they use different methods of measuring so they aren't going to be the same. Nothing sinister.

Just makes for mixed messaging easily exploitable by the media... I would think that the USGS, with its wider coverage and influence, would be the standard bearer, but smaller numbers don't make for quite as dramatic headlines. Not necessarily faulting OGS for that, just wondering why they wouldn't calibrate their methods to achieve closer results to line up with the standard bearer.

I think it also depends where USGS is getting their data. I would imagine OGS has a more local network and USGS might be using a reporting station out of state. OGS did bring their number down to 4.3 at last look.

Updated the list and things are definitely off to a fast start for April.

Maybe these will get ODOT to speed up on replacing them. :-P

I don't see that happening, as the Oklahoma Legislature is voting on reducing by half their "off-the-top" money to increase funding in education.

[Plutonic Panda]

Holy sh*t that one woke me me up they're getting bigger

[Plutonic Panda]

Multiple aftershocks... That had to be above a 2.0...im guessing 5.0 or a little bigger

[crimsoncrazy]

Felt a boom and my desk shook at work. I-40 and Morgan.

[Plutonic Panda]

omg... its horrible!!!! there blood everywhere and screaming!!! WHAT IS GOING ON! HOW COULD THIS HAPPEN? what.....is that? holy...

naaaaa, i'm just kiddin. it did wake me up though.

[venture]

Hmmm...heard the rumble but didn't feel anything. I doubt it would be anywhere near 5.0 with no shaking down here.

[venture]

4.1 per USGS

Man, then maybe the earthquake wizard is playing a late April fools joke on me because that shook pretty darn good for about 10-15 seconds and I just kind of laid there and thought "ok" and then it shook again for another 3 seconds and then again after that. They seem to be getting bigger though.

That's so weird how I'll feel a smaller one and then like the other day we'll a 4.5 and I won't feel it

[venture]

[Plutonic Panda]

Yeah.... It's saying this was only a 4.1.... I wonder if some 4.1s are bugger than others though

[KayneMo]

Didn't feel anything or remember hearing anything here in Norman!

[venture]

I think depth and location can play a role in how it is felt, even if the magnitude is the same. Usually anything over 4.0 we would normally always feel here in Norman, but now it is hit or miss.

[Bunty]

A 3.7 hit in the same area about 45 min. later. In Stillwater didn't feel or hear it or the stronger earlier one, or the two weaker ones near Perry that also hit early Thursday morning.
