The US Army Corps of Engineers has been letting ALOT of water through ALL of the SD Missouri River Dams, wonder if that has SOMETHING to do w/ this earthquake(just wondering)?

Thanks, that was my question...

false teachers in a mass “prayer meeting” in Texas,
earthquakes in strange places,
riots and random mob violence...

There is a theory (actually many) that hold that water saturation is the cause of some earthquakes. The great San Francisco quake may have been caused by the filling of Crystal Springs Reservoir that sits directly on to of the San Andreas Fault.

There are a number of somewhat inactive faults that run up through ND, SD and NE.

I noted shaking/rumbling ground movement from several Central/South American quakes of larger magnitude when I was a missile crew member at Minot ND. It was enough to cause the suspended crew capsule to noticably sway and to put all of the Minuteman missiles into a gyroscopic safe/locked mode.

I found it Alaska it was hard to even notice anything near a 4.0. You had to be setting still and quiet with a point of reference like arms on a desk. You still might miss it then.

Dallas had one yesterday. That’s Texas, South Dakota, and South Carolina. What’s the weather been like in SD and SC? Texas has been having the worst drought in over 100 years so that might have been the cause. That, or Australia last year and Japan a few months ago so it’s made the rounds and is hitting the US. Bad times ahead, folks.

Interesting how a little 3.5 quake can can be extrapolated into “We are all going to die.” It doesn’t take much in FReeperville...sigh.

Actually, the tree huggers will blame this on unnatural fracking and use that as an excuse to shut down oil drilling in the Bakken fields.

Pretty much in the middle of nowhere. I have an uncle near there and he didn’t feel it at all.

I’m not doing that here at all. Just noting that it occurred, and it’s a place that’s not accustomed to having them. And you have the gall to lament jumping to conclusions with your “...sigh” - Sigh indeed.

But South Dakota does have earthquakes, just not very often. About 1 every 2 years on average but sometimes 5 a year.

Back in the 80s I was on Alert at C-0 (Grand Forks) when the Missouri quake hit.

We did not feel it in the capsule but all the missiles in four Wings went into PIGA Leveling.

2.3 7 miles from Fountain Inn right on I-385 one tenth of a mile deep - probably construction. I know it was only 15 miles from us and we didn’t feel a thing

Very infrequent. Which is why it’s been made note of.

We were driving thru the state a month ago, and couldn't find a room in Rapid City (we're dastardly smokers, and that burg has citywide no-puffing-in-hotels legislation) so we continued east to Wall.

The sticker on the mirror in the bathroom explained why the cold water starts out at over 100 degrees due to underground weirdness.............so they indeed have fracture stuff going on in South Dakota.

We here in W. Iowa and E. NE are STEWING in So. Dak’s water and have been ALL summer!

I've been waiting to unload!! Your DOT totally sucks! A month ago, we left Minnesota and drove down I-29 headed toward Kansas City; we'd been told that the flood detour was "no biggie....15 minutes at the most".

All well and good, so we took the detour sign east on I-80 and got 40 miles with NO clue as to what to do....we bailed out and went south on highway 59 and circled for four hours and 200 f*cking miles, due to Iowa's contradictory detour signage.

If we hadn't stopped at a rural gas station to take a well deserved piss (and found two salesmen who were headed south and knew the "follow us" route - signage bedamned -) we'd still be circling.

Anyhow, back to your original point -- we were dumbfounded at the devastation in that area. This was July and barns a mile off the interstate still had water to the eaves. The politicians and media moved on.....

Mountanous enough however — colliding or slipping subcontinental masses are certainly still possible.

What is the meaning of the “M”? Does that qualify the quake as opposed to just “3.4”?

No, the Wilson Basin that the Bakken is part of goes that far south but the Bakken oil field does not reach to the South Dakota Border.

Yep, those quakes back in the late 70s sent a pretty good ground wave up through Minot that affected the entire wing, I was at I01 for one of them. In the early 80s I experienced windows rattling at our house in Bellevue NE from at least one quake elsewhere and the Humbolt fault which runs up through parts of NE has given us a couple of pretty good rattles over the last 20 years.
