5.4 EMSC Quake in OK- USGS- 5.1

Wow, that was intense. Waiting on USGS to report this, but it looks like at least a 5.0. Or it could have been a 4.5 very very close to the station.

Jesus, that is showing up at Yellowstone.


I was trying to get data, saw it start to come in, and then poof, gone. The station is CROK on the OK network that went out. But it did come back. A lot of red on my spectro. I know some people had to feel that.

Note that this is being reported as a 5.4 by EMSC

USGS has still not reported, but no, that doesn't look good against the fracking companies. That's a damn big quake, and surely rattled some nerves.



USGS just reported in at 5.1. Discounts, anyone? That sounds a lot less frightening than a 5.4.

seeing 2.6 (usgs)

edit - sorry that might have been an earlier one

Was there more than one possibly?

a reply to: TrueAmerican

Is it possible that the oil companies doing the fracking have managed to somehow censor quake reporting?

USGS is reporting it as a 5.1.

USGS

they just updated and reported it. Nice catch though, they seem to be getting bigger and bigger there...

Not possible olaru12. There are too many publicly available seismometers. Take a look at this screen grab from the GEE software. The center line is from a seismometer in Tulsa, OK. The top one is the Puget sound area in Washington, and the bottom is from Mammoth (Long Valley caldera) in eastern California. You can see the seismic waves already hitting the seismos in California and Washington.
When the ground shakes, there is no way to hide it.

I will be curious if Ketsuko felt anything.

Weird, I would like to feel one someday before I die, same as I would like to see a tornado. Weird, I know.

Stay safe all.

Explain to this new american like I am five years old, does OK have a history of earthquakes?

a reply to: zazzafrazz

It appears related to fracking. Since they started, earthquakes in the area have exploded. They're all in the 2 km deep range it looks like.

True, but it is possible to pad those magnitudes a bit. EMSC reported it as a 5.4, and then changed it immediately to 5.1 when the USGS reported it as such. Note the location, off to the west in the state, and away from the usual spots.

New Madrid Fault

It is a little east of Ok. but there is a lot of doom porn surrounding it.

a reply to: Zaphod58

More precisely, scientists believe the quakes are related to high-pressure wastewater injection wells; wastewater generated by fracking.

Short answer. You are spot on...fracking.

a reply to: Olivine

Yeah, i was just reading more about it, and saw that. The first articles I saw said fracking, but you're right.

There is a new type of fracking done by a Canadian company that uses frozen natural gas that dissipates back up into the well. It doesn't poison the local water, I wander if this would still cause the earthquake issue though even if it is a step in the right direction removing all the toxins?

a reply to: TrueAmerican

I think the reduction by emsc is probably because their initial magnitude solution was from using teleseismic data: stations far from the epicenter. Once IRIS publishes the waveform data for the event, EMSC is able to fine tune their findings.

But I don't work there, so who knows.

There have already been 1062 felt reports. That will surely continue to rise with such a shallow hypocenter.

i dont think this is a fracking thing . this pic shows an overlay of fracking sites and earthquakes. the green zones are the fracking sites and as you can see most of the earth quakes are not in those zones although there is some overlap towards kansas, but most of the earthquakes are happening just east of a large AFB and east of OKC. Oklahoma i believe has now surpassed Cali as the most active place in the u.s. and it was never this bad in the 35 years ive lived there.

for a great animation
ETA
i need to update the EQ part of that pic and probably the fraking sites as well but just watch that animation and be scared

Oklahoma has had a history of earthquakes since the 70s, at least. But mostly due to fracking and in the 2-3 range. But lately the earthquakes have been stronger, like this one that just happened. It's a little concerning.

it seems certain now that fracking can cause tremors. is it really worth the risk?

In Denton, Texas the city banned fracking but the state overturned it. All in the name of money. Who cares about safety and health?

That ticks me off. It certainly isn't worth it!
