Oklahoma Earthquake Activity

[venture]

Other thread is long gone, so going to start a new one.

Friday Afternoon's earthquake details, this one is the strongest so far this year I believe and reports did come in from Edmond according to KWTV.

Earthquake in Edmond yesterday? I didn't know!

Earthquake in Edmond yesterday? I didn't know!

No. They just felt a little there. Map pinpoints epicenter.

[Luke]

Although it said 3.6 in magnitude, what does the "IV" represent on the map?

[venture]

This probably won't paste right...but here goes.

Venture79,

Is there anyway you can create an overlay of all the earthquakes we have had in Oklahoma this year? Is there a connection?

Are there any geological formations in Oklahoma like the Palmdale Bulge in Southern California?

Thanks

[westsidesooner]

Possum, this doesn't answer your question but I found it interesting. It shows all the earthquakes in Oklahoma between 1977 and 2001. The earthquakes shown in red are the ones strong enough to be felt.



Edit: I just found this for 2009.

Thanks westsidesooner! I'd have to go back and count all the dots, but it seems there might be more dots along the Canadian River?

I am going to read up on this.

Good Job!!!!

[Jesseda]

we had a 3.4 earthquake near mcloud tuesday, did anyone feel it?

[westsidesooner]

I had a lot of free time this week while waiting on the gas lines in our yard to be repaired. Wait on the plumber, wait on the contractor to put in the new line, wait on at&t to repair phone and internet lines the contractor cut, now Im waiting on ONG. Did I mention that patience isnt one of my virtues. lol I feel like a hostage in my own home.

Jesseda...I didnt feel it but heard something on channel 9 at noon (while waiting) and that reminded me of Possums request of Venture. I tried to find some info online about it but wasnt succesful. Did it do any damage?

[Jesseda]

not that i know,, i go to this web site Latest Earthquakes - Last 7 Days and it tell you all the recent earthquakes around th world, i click on the oklahoma area

Lindsay, Oklahoma seems relatively active.

[Jesseda]

it seems we are having more and more these past few years, or at least stronger ones?

[Luke]

it seems we are having more and more these past few years, or at least stronger ones?

With all the Californians moving out here, maybe they're bringing the earthquake mojo.

[venture]

it seems we are having more and more these past few years, or at least stronger ones?

We have a pretty active seismic zone in Oklahoma with around 100-150 earthquakes a year. There is one main fault line in SW Oklahoma which the Wichitas developed on...but doesn't look like there is a lot of activity there. There are others throughout the state and our ground (dirt) type also plays into things.

[westsidesooner]

I've heard there were up to 8 earthquakes in the state today including a 3.4 near ADA and a 2.7 near Jones. Anyone feel them? NewsOk's story mentions 6. http://newsok.com/four-earthquakes-h...rticle/3396104

I just hope we don't break off and fall into the ocean.. oh wait, that's what is going to happen to my prior state of CA! Earthquakes.. pshaw! These are nothing ... just little tremors. :-)

[Bostonfan]

Thought I felt another one in the MWC area around 9:00 tonight. Anyone else?

[Karried]

yep, heard it on the news .. another one!

[venture]

This is what we have so far...9 total.

Surface just opened up in that area, lava is shooting up like crazy!

Surface just opened up in that area, lava is shooting up like crazy!

Whew.....in a way thats almost a relief. A volcano will only take out the area near it....initially. I was worried it might be the aliens from War of the Worlds trying to break through the ground. You know we did have a pretty good lightning storm the other night.

Any new quakes today???

[Luke]

This can't be good for the crosstown.
