2015 Oklahoma Earthquake Discussion

[ljbab728]

I'm in NW OKC and only felt a couple of small movements. I really wasn't sure if it was an earthquake.

[David]

Definitely felt that one, first one I've noticed at my new place.

[Pete]

I probably feel them more than most since I'm on the 3rd floor of a building built in 1910.

But still, that was by far the biggest and scariest one. Went on for a while.

Lasted along time almost 30 seconds... My friends felt it in Bixby

This one wasn't as bad as the 4.3 Edmond quake on Dec 29th where I live but it was still scary. I am starting to get pretty tired of this.

Someone with the capability to put in the necessary links needs to start a new thread. I do believe we are in 2016 now.

[Pete]

Looks like this one could have been a 4.8.

I believe it. It was a bit scary. I bet there was some damage.

[Tundra]

Saying 4.8 in Alva

[ljbab728]

Yes, USGS says a 4.8 near Alva and a 4.3 near Fairview.

I would guess that is the largest in the state in quite a while?

I don't like this trend: Bigger and more frequent.

[Pete]

Looks like tied for 2nd largest behind only a 5.6 near Shawnee 4 years ago.

Felt it in good in NW OKC. Initially thought my roommate was leaning into his dresser which shares a wall with mine, but when it lasted longer and longer I knew that couldn't be it. Had a glass clink and rattle loudly for like 20 seconds and the computer monitor took on a good wobble. As someone who never feels them, this was pretty "big" for me, lol. Most people did seem to report more dramatic shaking than me, but I don't know if being in a rolling chair has something to do with it.

Crazy how much shaking there is for a 4.8 so far away. Can't imagine a 4.8 centered in the immediate metro though something tells me we'll eventually find out.

[Tundra]

4.3 in Fairview , then a 4.8 in Alva simultaneously

[Pete]

Looks like there may have been a 4.8 and 4.3 about a minute apart.

I definitely felt one right after the other.

[sooner88]

That was definitely the longest I've felt. I'm hoping we don't see any damage in all these old, mainly brick, buildings that have been restored... But if they continue down this path it only seems inevitable.

[ljbab728]

Now USGS is showing an aftershock near Alva of 3.4 and another 3.4 near Fairview.

[KayneMo]

4.3 at 10:27:28
4.8 at 10:28:00
3.4 at 10:37:22
3.4 at 10:49:46

I thought the 4.3 and the 4.8 was a single earthquake that tapered off in intensity and increased again.

[Pete]

That was definitely the longest I've felt. I'm hoping we don't see any damage in all these old, mainly brick, buildings that have been restored... But if they continue down this path it only seems inevitable.

This is why you see so little brick in California.

Of course here, brick is perhaps the most common building material at least in part because there has never been any real risk of earthquakes.

I bet there are lots of cracked brick walls after tonight.

[Pete]

Yeah, this is normal:

The 4.3 was upgraded to a 4.7. There have been eight aftershocks since the 4.8.

I'm in Portland and was on the phone with my sister when the earthquakes happened. She felt them pretty good just west of downtown Oklahoma City. Earthquakes have never bothered me much, but this trend is one I'm not comfortable with.

[Bunty]

I was watching channel 5 news during a commercial when I sensed some shaking while seated in my recliner. I asked myself was that an earthquake? Then the news returned with them commenting an earthquake just happened and the studio lights were still shaking. Since the earthquake didn't come with a loud noise, it didn't startle me, like they tend to do when they're centered much closer to me.

The frequency of earthquakes of 2.0M or greater are trying to rise up to past peak levels again.

That's strange. Didn't feel a thing this time in west Edmond.

[Pete]

I have a 55" TV sitting on a stand in my living room and when that first quake hit, you could see it shake pretty strongly.

For a minute, I was afraid it was going to topple
