4.0 EQ Dead Center New Madrid (Missouri)

A 2.8 in Oklahoma about 2 hours ago. I have noticed NM, OK and a spot in north central Arkansas (next?) seem to have had quakes close together in time in the past. Makes me think the failed east-west rift from Texas thru Arkansas intersects with the Reelfoot rift underlying the NM fault zone and they affect one another.

Given all the advances in geology, including GPS and study of the magma plumes, I wonder if a magma plume is rising under the rifts and will make them active again. Volcanoes on the way???

Heh, and we had a 5.0 quake here in V.A. last year and a few more quakes recently. As recent as a few days ago, a 2.7...

I think you are on to something. There are some extinct volcanoes in the Ozark mountains in western Arkansas.

During that huge swarm in Arkansas over the last 18 months, I often wondered if those little fire balls were coming up for a little air, so to speak......only time will tell.

I actually feel natural gas fracking was the cause of those swarms. However, only time will tell.....hindsight is always 10/10

Haha Volcano in the middle of the midwest, now that would be some news...

Right on schedule.... Those disgusting locust #s will be at the surface any day now. It's gonna be a looong year....... COME ON GEARS !

Hey in V.A. we've never had quakes, the last one was 1900's i believe.

Some Californians and others think a 4.0 isnt a big deal. Well it is, depending where you live.. California is built on sand. Strike the sand with a hammer and it is pretty well absorbed. Strike bedrock, and well, your hands are gonna ring.

I'm really stating to dislike all the middle America and east coast saying their earthquakes are so much worse. Stop your crying japan's earthquake makes you look like a little girl seriously and i wonder if japan is all on sand as well lol because its a island. I can understand how this might seem so amazing just recently having to deal with earthquakes but get over your self's. How much damage has it caused? How many people got hurt? can you see the damage from earthquakes everyday in your streets like in California I highly doubt it. Also California isn't all sand lol sorry to ruin your dream that everybody in California has beach front property we don't

COGs indeed.

You know, like REX84?

Well and if I'm reading the Map on RSOE EDIS correctly, the areas in Japan and Indonesia seeing tectonic activity are actually on the opposite side of the tectonic plate the New Madrid line is connected to.

This isn't much of a coincidence at all.

the coast is sandy, you don't want to live on that, during an earthquake water down in the sand , when it shakes it turns into quicksand, buildings have much more damage. This also happens when buildings are build on filled in reclaimed land.


people are concerned about the new madrid fault because of the huge earthquake (actually 2) the mississippi river actually reversed the direction of flow. they think these earthquakes were in the 8's.. this was back when there wasn't alot of people.

Based on what you've read in there, do you think it's possible that there may have been some foreshocks that went unnoticed because of lack of communication and/or the sparse population at the time?

Yes. The document presents population data of the time, and shows that there were only 2-6 people per square mile near epicenter, and less than 2 per square mile in the immediate areas surrounding the epicenter locations. The New Madrid was essentially the western border of European colonization at the time. Therefore it is possible that there could have been smaller foreshocks occurring that went unreported or were mostly shrugged off.

But a key point of interest is:

A common assumption -one that we hold also- is that the currentseismicity is illuminating the most active faults, i.e. those that ruptured in 1811-1812 and also in pre-1811activity. The hypocenters are located with regional seismographic networks operated by three universities(Saint Louis, Memphis, and Kentucky). Within the NMSZ, which is defined by the epicenter alignmentswithin 35.5-37.0'N and 89.2-90.5'W, the-epicentral uncertainty is < 1 km, but depths are poorlyconstrained. Since network monitoring began in 1974 more than 3000 NMSZ earthquakes have beenlocated (Herrmann et al 1994), none of which reach moment magnitude M 5.0.

And so this 4.0 fits within this paradigm, and is likely just long term, continuing seismicity on the fault structure. It's just slightly a bit bigger than usual, and let's hope, that's all.

Well I live about 30 miles north, in Cape Girardeau and it didn't even wake me up this morning. But since I spent some time in CA, this is a hiccup compared to what happens out there. Amazing, all the local news coverage of it around here as if it was the big one! Compared to the 1811-1812 quakes that rattled this area, this is nothing.

I think the whole point is to make people aware of the New Madrid zone , it won't be so minimal if the whole thing starts shaking.
Also , it's nice to know average people are on top of this kind of stuff , I'd rather be over-prepared than not at all.

Japan was such a devastating event and we all realize that , do you honestly think people forgot?

Do a search on the New Madrid , where all the nuclear locations are , natural gas , population , etc then say something like that.

I believe that Madrid is waking more. That 4. is rare for this fault. I have been watching the arkansas area quakes for a long while; Before the fracking was admitted in the Guy area/region. I do not believe it is time to duck and run, just always be mentally and physically prepared for any emergency.
Years ago I came upon some newspapers up in my grandma's attic(1978 to be exact) and I found one from the earthquake 200 years ago. People were having a picnic or celebration out by the Arkansas river. They described the rising of the water and how it "peaked" and then went into reverse(reverse for the Mississippi river, which is actually the natural course of all rivers to run). The fault line runs under the river, this is why it is felt in so many states. Furthermore, the river ran in this reversed course for three days.
When I was young we all were taught that the Madrid is the worst fault in the lower 48. And, we should not be so complacent of a 4 increment, nor should we be fear-mongering:Be alert!
And okay, I have really been wondering what does MSM mean when you guys talk about that?

Love and Peace~

There is a dormant volcano in Arkansas. That is how there is the Hot Springs.
There is a dormant volcano in San Antonio, TX. It would take a super-volcano eruption to awaken this sleeper. But, that is why is such an event did occurr, nobody would be safe from Montana to Texas.

Thanks for your thread EvolEric,

I have a dear friend in Poplar Bluff.


colbe

I'm in St. Louis and was up at the time of the quake, didn't feel a thing.

80% of ATS Parody:

-I feel this is just the beggining

-This could be before the huge one

-A good contact told me to buy supplies for at least 18 months, he/she didnt explain much, but i trust my contact and so should you

-Did anybody else hear a loud noise while the tremor was on? It was like a loud buzz or beeping sound.

I Live in st.louis Mo. so I did not feel the earth quake but,if new madrid were to have a big quake we here in st.louis would be in trouble also people in Tenneesee would feel it for sure. It is a scary thought that I live so close to a fault line that could cause such mass destruction. The last time it had an earth quake the river ran backwards I think back in the 1800;s. I do not like hearing about this even if it just a 4.0 the news here wasnt that worried about it they were like well it was just a small quake.

There was a quake in IL a few years ago and I felt it but,I just got up to turn the light off my tv started shaking and I thought it was possed by a ghost lol. so i turned the light back on and was scared til i found out what it was hahaha
