I heard the one in Guthrie today out in Harrah. It was odd because I thought it was just a truck driving by but it lasted a good 45 seconds or so. I went outside and looked around and thought it was a plane or helicopter also but nope, never felt the ground shake either, I just heard the rumble.

Dang, today, Tues., there has been, so far, 15 earthquakes over 2.0, counting three from Kansas. At least most of them have been under 3.0. Ten to 12 is more typical for a lively day. The way the people are becoming so complacent and accepting about earthquakes, it's like the frog being in hot water doing nothing as the temperature slowly increases. By the time the water boils over or a record breaking earthquake comes, it will be to late to take action.

4.1 magnitude earthquake recorded in north-central Oklahoma | NewsOK.com

[OKCisOK4me]

Didn't feel that one...

[Bunty]

Didn't feel that one...

I didn't either. But I know this evening around 7:25pm that I heard the sound of distant thunder and then my house squeaked or creaked. It didn't seem a 4.1 or any worse than usual.

[silvergrove]

Ignore, didn't realize there was a discussion elsewhere, you can delete this.

[Plutonic Panda]

Went ahead and created this since we're into March now. :P

Look 4 threads down.

[Plutonic Panda]

I have no idea how I missed that. Sorry.

Felt two good shakes yesterday at 530 pm and 543 pm. 2.7 and 2.4. I think they were centered right under me. Last week had 2 nights with 4 each night. I'm having problems sleeping when you get hit with 4 during the night. grrrrr

Well, dang, 18 earthquakes took place Tuesday, 3/12/2015, with 3 of them in Kansas as reported by USGS. That's about as numerous as they get in a day. OGS had 20, all in Oklahoma. All were under 4.0 M. I try not to worry too much about them, but if an unusually strong one happens, like a 4.5, or greater, I'm going to be extra worried it could be the foreshock that comes before the big one. Considering the highly intense complacency and acceptance Oklahomans have developed toward the earthquakes, it's, no doubt, going to take a new record breaking big one to get the oil companies to try doing more to control them, unless they first stop their activity from the price of oil dropping to $20 a barrel.

As evidence of the complacency, little more than a hundred people showed up for the recent town hall meeting on earthquakes in OKC at Kerr-McGee Auditorium on the Oklahoma City University campus. Compare that to over 500 who showed up about a year ago for the same thing held in Edmond.

Quite the swarm since last night, including 4 exceeding 3.5 and 2 exceeding 4.0. I felt minor shaking from this morning's 4.2 here in OKC though it was barely perceptible. Wonder if the swarm will continue.

[Hollywood]

Nice little shake near 150th and Western.

[mkjeeves]

Shake rattle and roll!

Near Lake Overholser...

[jerrywall]

Just had a pretty strong one up in Edmond. My monitors shook on their stands, and my desk moved.

[Ginkasa]

Felt in Bricktown

[RickOKC]

Currently on the south side of OKC and felt it here, as well.

[Dustin]

That was a biggie. Or maybe the epicenter was closer to OKC this time... lol

[rezman]

Wow! .... 178th & Western. One good jolt followed quickly by a second, and finished off by a short shaking..... 3 seconds tops.

[mkjeeves]

I've felt and seen the jiggle before. We had one about a year ago that a boom at the beginning. This was the first time where it started with a strong side movement.

[Jim Kyle]

One solid jolt at NW 122 and Council, but one of the three strongest I've ever felt (the other two being the top two for the state).

[LocoAko]

Felt nothing in south Norman.
