Title: Earthquakes, or "pre-shocks"?
Post by: patric on April 16, 2013, 03:01:12 PM
Did anyone feel the quakes last night?

This was the largest one

After the 5.6 rolled through and stopped the conversation we were having in the kitchen, we added earthquake insurance.

I'm hoping we over reacted.

Yes, I did.  The 1:56 (4.2) and the 2:26 (3.3) ones.  First was very noticeable, the smaller one, barely so.  Was spending the night in a mobile apparatus, and when it happened, looked out the window to see what the wind was doing.  Dead calm.  Looked across the street and two other people opened their doors to look around.  Have felt them before near that location.  There have been a few more today.

This shows the whole world, and you can zoom in on our little corner of it....very cool.  Note the really big one in Iran...about 12 hours earlier, as near as I want to bother calculating.  I think it is a plot!

No, I just felt some after shocks.

Oklahoma Insurance Commissioner's advice: Buy earthquake coverage

http://stateimpact.npr.org/oklahoma/2013/10/30/oklahoma-insurance-commissioners-advice-buy-earthquake-coverage/ (http://stateimpact.npr.org/oklahoma/2013/10/30/oklahoma-insurance-commissioners-advice-buy-earthquake-coverage/)

QuoteA week after the U.S. Geological Survey warned of increased earthquake risk in central Oklahoma, possibly because of oil and gas activity, state Insurance Commissioner John Doak is urging Oklahomans to buy earthquake insurance. Most homeowners and renters policies don't cover earthquake damage, which can cost $100-$150 a year. Oklahoma's earthquakes are expected to continue and don't appear to be naturally occurring, federal seismologist Bill Leith wrote in in the USGS alert.

Something about that seems pretty messed up.  Should the oil and gas industry provide earthquake insurance as part of doing business if they are the cause of the earthquakes?

This is Oklahoma, the government doesn't work in your interests.

Quakes, pre-shocks, after shocks, I felt none.  The only quake I felt in Tulsa was the one from a few years ago, it rattled everything pretty darn good around 9:30 am. Musta been back in 2011.

He's posted a lot of stuff only to contradict himself later. Guess he needs to go jogging and count distance markers in Omaha again. Or is it Ft. Worth? Or is it Austin? Toledo? Maybe he's been sniffing the fumes from his '79 pick-em up truck..........

7:36 felt the house shake pretty good.  Anyone else feel anything?

Nothing.  Sure it wasn't an over-size going down I-44, close as you are to the highway?

There's all sorts of heavy industrial equipment moving up and down the street near my office, our building gets a good shake many times a day.

My bad.  I was fracking.

Felt pretty solid to me. Perhaps it was this one?  http://earthquake.usgs.gov/earthquakes/dyfi/events/us/c000lvld/us/index.html  

Don't know how fast earthquakes travel to know if the timing was right and some areas farther away from an earthquake can actually feel it more than closer depending on the topography the waves travel through.

I often feel earthquakes at my house that some others say they did not feel at other locations in town. Perhaps it's just the bit of land I am on or the way the house is built. Perhaps it could have been a large truck or something, but honestly didn't feel like that type of rumble.  It was a slower "deeper" up from the flooring type of feel.

Your house isn't on an ancient burial ground is it?  ;)

Very dependent on what it is traveling through.  Huge variations based on material, and the type of wave....  Google is your friend!

Anyone think the injection wells are actually contributing to this? Not fracks, disposals.

LOL!  Only if they can reach 70-300 kilometers.   The whole frack/well theory is rather ridiculous when you look at the where earthquakes take place and the massive amounts of energy at play.   

No matter how fast the mosquito flies, it is very unlikely it will shatter your windshield.

That's what they said about foam and the leading edge of the wing of the Space Shuttle. Common sense is neither common nor sense.

Oh, cool!!!   Another oil industry cliche' one liner.... untrue of course, but very clever!!

REAL scientists - those not on an oil industry payroll - know what is happening and are willing to say so.
