3.7 earthquake here
About 15 minutes ago, northeast part of town (Greeley CO). Loud boom, the building jerked once. Don't know about reports of damage yet.
And, yes, we're smack dab in the middle of fracking country.
Sheeeeeyut!

3. My first thought was the fracking in your area...
I was watching 9 news and their incredible cluelessness. That it could be related to fracking has clearly not even remotely occurred to them.
sigh....

4. Believe me, OUR first thought was fracking.
I can't help hoping that it scared the crap out of our mayor and city council. We're kind of tired of being told that our concerns are irrelevant.

They blow up shit on the surface when fracking? My, my, the odd things one learns on DU...
:whatever:

Morons.
They really have no idea how far below the earth's crust an earthquake begins, do they ? A really deep 'Fracking' site may go down about five miles. An average 'shallow' earthquake starts about 35 miles down. An earthquake starting about 5 miles down produces nothing more than a pop, and maybe a second or two of shaking.

I worked the DJ Basin where Greeley sets. I worked out of the "camp" in Ft. Lupton.
We never fracked a well deeper than 5500 feet.

H5 to you sir. That made me laugh.

With what knowledge they seem to have about geology, I would like to suggest they toss a virgin into the fault line to appease Gaia. It's not like they are in short supply of male ones at least...

Well, we don't call them DUmmies for nothing. :thatsright:

My understanding is that is usually as far as they go - but I figured Id list the theoretical maximum to illustrate the ridiculousness of the claim.
The odds of 'Fracking' causing an earthquake are about as likely as giving oneself liver damage by scratching an itch on one's forearm.

The "D" and "J" sands are relatively shallow by drilling standards, I recall encountering them one time at around 7000 feet, but that was outside of Kimball, NE.
Even the Bakken shale, which is driving the North Dakota oil boom, usually comes in at less than 8000 feet.

So. Calif. just had a 4.2 earthquake near Westwood. It was approx. 14k feet deep. I'm pretty sure there isn't any fracking going on in Westwood.

The part I had the biggest problem with was the 'hearing a boom.' Deep blasting doesn't go 'boom,' just surface demolitions...well, that or a DUmmie trying to weld a damaged gas tank...

Here ya go, DUmb****s.
I knew about these in College, in.............................1982.

I was within the radius of an earthquake once in SC. It did sound like a boom and I felt a single ripple through the floor. It reminde me of being near a heavy caliber artillery strike where there was only a single round fired.
Fracking, however, is another matter altogether.
In every well I ever worked we used water, a specially-engineered sand, a gel and occasionally 15% hydrochloric acid.
The water mixes with the gel to expand the latter. It is then blended with the sand which is forced down-hole where is it pushed between the stratified layers of earth. The sand is engineered to hold its shape even under such tremendous pressures. This allows the product to filtrate through as one might expect water to pass through a field of ball bearings. This is a process that takes hours, sometimes days, with no potential for a sudden effect.
The closest thing to an explosion is the wire-line. Once the hole is drilled an iron casing runs the length of the annulus. Between the casing and the annulus a cement mixture is pressed for the purposes of zonal isolation; to keep the gas/oil from seeping out into unrecoverable layers and to keep sediments from seeping in. However, as you might imagine a cement-iron casing keeps the oil/gas from coming up as God intended so they have to blow a hole through casing.
For this the wire-line service sends down a long iron pole ~20' long with divets staggered along its length. In these divets are placed small shape charges about the size of a tea light candle. Collectively the charges can blow through the casing but that is all they are capable of doing. Anything stronger would damage the earth formation and defeats the purpose of the exercise.
I'm sure any fellow oil field workers would point out any errors I may have introduced but that's how I remember my job.
Proglodytes, however, despise facts.

Around here you drill down a few feet for water and hit rock.....then another 4-500 or more feet and still no water. So, they used to drop a sleeve of several sticks of dynamite in the dry hole and ...BOOM....now you had water. Same thing just different results.

I've been through a lot of earthquakes. They have to be pretty big, or really close by to get my attention.
I have heard booms a couple of times, but mostly things just tremble or maybe you get a woozy feeling of vertigo before you realize it's an earthquake.
The most concerning ones are large quakes that seem to last a long time with no sign of slowing down in intensity. Those are the ones your never sure if they are going to get worse, or are a prelude to a larger one. There are always after quakes to those, and are sometimes as big as the first. Also in earthquake country, you can get swarms of small earthquakes that go on for days. Those can get on your nerves too.
I live near the beach, so we have what's sometimes called liquefaction during quakes.

Yeah, point being that fracking doesn't normally involve any blasting on the surface that produce an audible bang, and while there are some ancillary operations that could conceivably involve explosives below the surface, fracking itself doesn't. Oil exploration used to use surface and subsurface explosives, in very modest amounts, to get seismic data, but that's largely been replaced by other means.

They've been fracturing oil wells for at least a hundred years.
My grandfather had shallow oil wells on his farm in the early 1900s, and told me many times about a guy who would deliver liquid nitroglycerin that would be put down the well and exploded. The nitro guy made as much for a single delivery as most people made for months of work. They continued the practice until one day he hit a big pothole and nearly vaporized himself, his wagon, and a pair of mules. That was the end of the story. I don't know how they fractured wells after that, probably just dynamite.

January of this year? The epicenter was about 5 miles from my house in Edgefield, SC. It was after the ice storm and the power had just come back on after 3 days. I'd just returned from Bragg. I first heard a loud bang, immediately thought it was maybe a transformer blowing, and it seems like a nanosecond later, the shake happened. Actually, it all happened within the matter of nanoseconds. Knew a couple that went up to Clarks Hill to stay on their houseboat because they had no power, but had a generator on the houseboat. They said it shook the hell out of the lake.

No. Late 1990s
