All the anti-fracking nut cases will go wild with speculation on this.
Caused by fracking!
How does anyone even know?
Probably caused by fracing a well in South Texas.
This will give the anti fracking groups a big stick...........
Since half the state is flooded, I’d watch for a tsunami warning...
>>>How does anyone even know?
The USGS has these devices called seismographs that are able to detect earthquakes to enable them to report when they occur.

I’ve done a lot of driving between Aberdeen and Britton, not to mention the puddle jumper flight from Aberdeen to Minneapolis. The amount of flooding the last 14 years is impressive. In the bad way.

Yeah, but without those, nobody would have known. ;)

Since a lot of the flooding has receded, it might be that this quake was a result of the stress of the weight of all that water being gone, and the land underneath springing back... just a theory.
isnt an earthquake in SD a bit unusual ???
Most earthquake maps don’t even show quakes this small.
It was sarcasm on my part, but only just.
Remember the magnitude scale is based on numerical orders of magintude.
A 3 for example is ten times as strong as a 2.
That means, working backward that a magnitude 3 “earthquake” is fully 1,000 times weaker than a 6, which is pretty much an earthquake.
5 is enough to get one’s attention, and stop everyone to turn on the radio or find a USGS map.
4, is already now 100 times weaker than the 6, and probably won’t even be felt unless you happen to be right above it.
3 is so small really - nobody would know if it wasn’t measured like that. Seriously it’s insignificant.
The Mayans know.
>>>isnt an earthquake in SD a bit unusual ???
Compared to California, yes.

Did it make a “boing” sound? :)
One of my friends lost several thousands of acres of land to flooding. I did not know it was finally receding. That’s really good news.
Those are daily occurances for us here, but in SD? hmmmm once in a while.
the Russians gave it a 2.7
Probably not. It’s located south of the Badlands in the middle of nowhere, but is next to Wyoming, home of Yellowstone, aka the caldera where earthquake rumbling occurs 24/7.
Sorry my post sounded condescending.
It just struck me first thing, this would be something liberals would eagerly use to block drilling, and my first reaction was to point out it’s not a big thing.
Sorry it ended up sounding like I might be calling your post insignificant. Unfortunate choice of words on my part.
But, let's just suppose that for a moment that fracking does cause earthquakes. 3.0? Who cares? I suspect that we could have 3.0 earthquakes on a daily basis and suffer no ill effects. Such a small price to pay for home-grown energy.
Now, if we were being hit by a rash of 9.0 earthquakes, I might say that we need an investigation into fracking before we suffer serious loss of life. But that isn't happening.
Then they should 'frack' DC til the earth opens up and swallows it! FrackUBO!
How is Mt. Rushmore?
I’m guessing from the distances this was either out in the Black Hills or Badlands.
I grew up in CA right on the faultline and don’t notice anything under 4.5.
“the Russians gave it a 2.7”
I hope it didn’t knock all the knick-knacks off the shelves at Wall Drug.
A 3.0?? Okay, who farted.....
Good one! LOL. Elsie of Indiana will love this as will reaganaut.
I was at a small county fair talent show and church service in SD with my aunt and uncle and someone told a similar joke. Interestingly enough they apologized in advance to any Democrats in the audience (there was 1 btw), no apologies for what may be considered racism, but they didn’t want to offend the ONE Democrat out of about 200 people there.
Not really, this one is located on the southern margin of the black hills where I’d expect to see one.
No MORMON curses as children may be reading this!
Not bad in the Spring or Fall; but the winters can be brutal and the summers VERY scorching!
You disrespect our Dear Leader.
I will now go nuclear on you!
Whoa! Are you forgetting your own approach to reports. I’m only reporting/quoting the source, BubbaJunebug. I did not disrespect the dumb bastard that you have now called “Dear Leader”. LOL
There! Fixed it for you.
Take me back to the Black hills
The Black Hills of Dakota
Did the earth move for you, too?
Not an uncommon misunderstanding. The magnitude scale is really comparing amplitudes of waves on a seismogram, not the strength or energy of the quakes.
So, a magnitude 3.0 is 10 times bigger than a 2.0 earthquake as measured on seismograms, but the 3.0 quake is about 31.6 times stronger than the 2.0.
Since it is really the energy or strength that knocks down buildings, this is really the more important comparison.
Need to go further west to the Rocky Mountains :)
