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

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.

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?

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.

This isnt Oklahoma related but I didnt want to start a new thread.

There were at least two more strong earthquakes in the phillipines today..
one was 7.3 the other was 7.8. Hawaii is under a tsunami advisory for this evening, which ay be upgraded to a warning later. Thats a lot of earthquakes on the same plate boundary over the last couple of weeks. Kinda makes you wonder whats going on down there.

No kidding about it being good that all that energy wasnt released in one mega-quake. Can you imagine? It still seems unusual for 5+ >7. quakes to occur on the same boundary in just a two/three week period. You gotta feel for those people down there. Maybe Australia is tired of being an island continent and has decided to move north to join Asia.

I don't want to believe it, but I think you're right. We've had a LOT of seismic activity over the last year or two. There's a chance that it's nothing out of the ordinary and we're just hearing about it more now than in the past, but I don't think so. pla

It's the start of the end, remember the world's come to an end on Dec. 12th, 2012. I'm prepared, bags are packed, I have an extra battery for my laptop and a case of Mountain Dew---let's go

It'll be interesting if they ever find out the cause of the earthquake swarm. R we sure its not the begining fo the trouble caused by the galactic alignment scheduled for 2012? :ohno: (actually I heard that already happened a few years back but I'm sure the doomsdayers will run with it) lol Had to throw that in.

I think the earth still has a lot of mysteries in store for us.....it's what makes life interesting.

Pretty much. Unfortunately we don't have enough monitoring equipment to know exactly what is going on. People have posted the point that we are sitting on a subduction zone so earthquakes will happen. The concentration in that part of OK County has some interest, but that is what the experts are for. For all we know it is the start of a new fault forming, gas/oil drilling, uplift in the crust, whatever.

I'll start getting worried when we see multiple earthquakes daily for an extended period of time. :)
