Earthquake N Central O K - Biggest To Date

[Terrel L. Shields]

They came out with 5.6 now but two people injured and lots of sheetrock and brick damaged. Inspection time and I bet a bunch of names will be added to a class action suit that is already ongoing.

Seattle had a 6.8 in 2001. After the building stopped swaying, a legal secretary, who was 23 stories up, called me and said she thought she was going to die. If you want to live out West, you have to be tough.

They have upgraded the quake to 5.8 and reevaluated a 2011 quake at 5.7, making this quake the largest in the state in modern times. There was an estimated 5.6 back in the early 1950s (pre-fracking) and a very large quake in the 1880s or so. Injection fluids are just the fertilizer that is spawning the quakes which are coming from a very fractured subsurface feature (the Nemaha Ridge) that was possibly a failed rift which seems to be bounding the Ozarks to the East. East of the Ozarks, the Mississippi Embayment is another fracture, the "Reelfoot Rift" which goes up into Illinois.

5.0 tonight, felt here. Cushing lost power, damage noted. Seriously are you appraiser caveating potential damage or seeing/reporting cracks, damage. This has got to be hurting property value I would think.

No problem here, but near the quake there is damage. And Cushing, OK is home to the storage hub where millions of barrels of oil is stored...and that oil is light oil that no one wants (it's being exported as fast as they can find a buyer and selling far below WTI prices). Where one of those tanks rupture it would make a railroad tank car explosion look like a candle in the dark. The problem is the Arbuckle formation where a lot of the disposal wells (which were almost invariably old played out wells from the 1950s-80s) penetrate. Those formations are not stable and naturally occurring earthquakes have been there for the eons...but the disposal wells are greasing the skids so to speak and making those 2.0 quakes turn into 4.0 and larger.

Welcome to the Ring of Fire:

I felt that one when I was in high school in the Portland area. Sitting in chemistry class and my desk started moving around. It lasted about 10 seconds as I recall. That's the only one I've ever felt. The last one that was felt in the Portland area occurred when we were vacationing out of state.

I was near the Landers 7.4 earthquake in 1992. It seemed like it lasted over a minute.
