All the anti-fracking nut cases will go wild with speculation on this.
Caused by fracking!
3.0?
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.
Brought to you by Captain Obvious....
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 half the state is flooded, Id watch for a tsunami warning...
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.
