I’m amazed it took 50+ posts
We don’t even notice earthquakes til the water starts slopping out of the pool. lol
New Madrid? None of the geowhizical geniuses claim to have a theory about what activates the NM. But I think shakes like this are precursors. In my view there is a lifting force from the Rockies, the Rockies being formed by collision, that translates all across the great plain, the Great Plain being a huge slab of sediment. The break is in the Mississippi River valley which is the natural low spot, and the NM is the area where lift pressure is the Max——think prybar with 1,000 mile long handle. Naturally I could be full of stuff but nothing that has happened in the half century that I’ve been watching runs counter to the above spiel.
Yes. I see per Wikipedia that it is actually 1811-1812. Sorry, I seem to have remembered wrong.
Check out the Wikipedia entry for New Madrid Earthquake. Some of the illustrations are amazing - I did not know that there is a huge rift under the Mississippi River and running NE. It’s very old and nothing new.

It compare the extent of the 1994 California earthquake and the extent of the NM 1895 earthquake. HUGE difference.
“Out in LALA-land, 4.5 would go unnoticed, unfelt, and definitely unremarked. Call in with 6.5 or better. “

Here in the Philippines, we are having quakes most every day now, since a 7.5, about a month ago, but most are under 4.5. We can feel the 4.5 quakes but only if sitting still.
Look to see if the US has a web site like this: http://www.phivolcs.dost.gov.ph/html/update_SOEPD/EQLatest.html

I live about 40 km from the Tagbilaran quake centers.
The USGS handles earthquake information. They have quite a bit on there.
In Sept 1990 we lived about 50 miles north of the New Madrid fault. Over the years we had experienced many tremors but the 4.6 tremor was centered only 17 miles away. Then a slightly smaller one happened 2 weeks later—so began the Browning Earthquake scare that gained national attention.
Until the 4.6 tremor, I had never heard the rumbling associated with the rolling vibrations that seemed to be coming up I-55 from New Madrid. We prepared, just in case. Thankfully, nothing came of it and we moved away the next year.
We are currently in the process of building a house about 100 miles from New Madrid and basing some of our decisions on the prospect of seismic activity.
That house would have to be built better than the ones in the earthquake zones of California! Good luck ... :-) ...
i thought cow_flatulenc was the most common cause of earthquakes in the west.
HAARP.... Akin to how they manipulated that “superstorm Sandy” to His Highness’ most advantageous political position.
You are not full of stuff, I enjoy every post of yours I come upon. Very satisfying, your are :)
Two additional today in the area, one within the last hour.
CA quakes jolt then roll.
We got the h*** out of there early Sunday morning.
Aftershocks?
No state is perfect.
When that baby snaps, there ain't gonna be no postin' to FR. Think of St. Louis and KC as the new Pompeii and Herculaneum w/o the volcano. Maybe a new Great Lake or two.
But don't worry, Obama will save us.
I may also be a carrier! After returning to Maine ... you guessed it .... quake! They even had a baby-quake in FL after I showed up.
That NM shake was unbelievable. Fortunately, practically no one was living out there when the Mississippi changed course, new lakes appeared, and the topography of the entire region was altered.
Lots more of these armageddon-quakes a-building out there: Mammoth in CA. Yellowstone. etc. Just remember that old SF Jug band, "The San Andreas Fault Finders"
