dinna notice nuttin' down here in Norman. Checked the telly; Hawaii friends seem as though they'll all be okie dokie as well.
Y'all can keep the shakin'. I don't wants it.

Didn't feel anything in Moore during the time.
From OGS:
Nine Earthquakes recorded in Canadian County: Several felt in Niles & Minco OK. 3/11/10 LATEST OKLAHOMA EARTHQUAKES!
The six largest earthquakes locations are very well constrained and on relocation we expect the magnitude 2.1 earthquake to centered with the cluster. The cluster of six earthquakes is 7 miles west of Union City Oklahoma in Canadian County near the border with both Grady and Caddo Counties. The cluster is about 11 miles SSW of El Reno.

Some details and graph at Oklahoma Earthquake Page
Here is a map I've been keeping updated on Google. Gives an idea where all the quakes so far this year have been for the state.
Oklahoma Earthquakes 2010 - Google Maps
At 4.4, it's kinda worrisome they're still prone to increase in intensity.
While I didn't feel today's quake, I sure noticed it. I was fishing at Lake Hefner, enjoying the weather, I noticed a series of waves. I was wondering what it could be, it looked like the wake of a boat, but there wasn't a passing boat. I get home from fishing, and see that there was a quake, and I put the two together. It's pretty interesting to actually see the physics of an earthquake. It was a mini-tsunami, I guess..
It looks like the Sparks 4.4 quake got downgraded to 4.1.
It is called being accurate. Look. I enjoy your enthusiasm that you bring to this thread and the weather thread, but it is time to pull back some. There comes a time to where posting inaccurate information for the sole purpose to get people worked up isn't very appropriate.
Venture, I can express my opinion as I see fit. To me, that is what I believe is the reason they scaled it back. Tell me, did they have an equipment at the exact epic center? I'm interested to know how can they determine the scale and location? They had just brought in equipments for the Jones and surrounding areas. This one was further east.
I have nothing wrong with opinions being expressed, but when they make accusations of falsifying scientific data...then it becomes out of bounds. I don't think there has been many earthquakes in this world that have seismographs at the exactly epicenter of each one. The only exception would probably be volcano monitoring equipment. However, there are numerous recording devices out there now - far above on the map below that we already had:
Venture, share more. How are they able to scale it by .3 down?
Just like when they scaled down the May 3rd tornado--it was for accuracy, not for peace of mind.
Opinions are not always fact. Why you "think" they lowered the magnitude has nothing to do with why they really did it.
Still corrupting young minds
I believe the Chile earthquake was first reported as an 8.2 or .3 and then later upped to an 8.8. I think the massive Indonesian quake a few years ago was first reported a little lower than it ended up being at 9.2. Thunder, revisions happen all the time.
Yeah I think you're right. I was really surprised to learn that it isn't the Richter scale that they use anymore... it's been superseded by the "moment magnitude scale." It uses the same format numbers and is also a logarithm, but I guess it's more about movement and force per centimeter. So if they're measuring to those levels of accuracy I'd imagine that the M-number does get refined as more detail is sought.
This isn't the only one. More to come.
