65. The quake that made the Mississippi run backward

Sat May 2, 2015, 02:16 PM

May 2015

was part of the New Madrid series. I sincerely doubt that even a great deal of ice melting would have a connection or even a correlation. The planet is pretty big. The geologic forces that cause earthquakes are far below the surface. An extremely shallow earthquake is still happening about 20km under the surface.

In 1991 I visited New Madrid and went to the earthquake museum there. Fascinating. One of the things that happened during the earthquakes was that large amounts of sand and water were ejected from the earth. They're called sand blows, and they can still be seen today, generally as circular areas where nothing grows in the middle of cultivated fields.

Sorry, I am really behind on responding to things marym625 May 2015 #58

Now if they had been fracking in the area.... daleanime Apr 2015 #2

I actually was wondering just that marym625 Apr 2015 #6

yes there is fracking questionseverything Apr 2015 #28

Well shit! marym625 Apr 2015 #35

No. Earthquakes in that area have been common for... TreasonousBastard Apr 2015 #3

I do understand that earthquakes are natural events marym625 Apr 2015 #7

Yes, changes in storm intensity and sea level affect plate tectonics. bananas Apr 2015 #4

Thank you marym625 Apr 2015 #8

And this is why that's no such thing..... daleanime Apr 2015 #9

I'm glad I am not the only one educated here. marym625 Apr 2015 #10

Geological time scales are SheilaT Apr 2015 #26

Yes, I get that marym625 Apr 2015 #31

You make a good point. SheilaT Apr 2015 #42

The quake that made the Mississippi run backward SheilaT May 2015 #65

I haven't visited, yet marym625 May 2015 #66

There was just a quake epicenter Galesburg Michigan marym625 May 2015 #62

Nepal is so far from the nearest sea that sea level rise contributed ZERO Binkie The Clown Apr 2015 #15

But, marym625 Apr 2015 #36

Fracking Earthquakes are usually around 3.0. Nepal was a 7.8 Travis_0004 Apr 2015 #40

I don't think it's all humans marym625 Apr 2015 #41

ya know, i asked a similar question in this forum a few years ago. mopinko Apr 2015 #11

I hope we learn it marym625 Apr 2015 #12

What physics lessons would that be? dbackjon Apr 2015 #19

that at a certain point a heating planet mopinko Apr 2015 #20

The atmosphere would have to get awfully hot dbackjon Apr 2015 #21

the heating of the oceans would mopinko Apr 2015 #23

No - the oceans warming a degree or two will do ZERO to the crust dbackjon Apr 2015 #24

No! Absolutely not. Binkie The Clown Apr 2015 #16

Thank you Boomer Apr 2015 #25

and how much does it have to rise marym625 Apr 2015 #33

"10cm or 15cm rise in sea level...." bloom Apr 2015 #53

Thank you very much marym625 Apr 2015 #34

From what I think I know about plate tectonics, SheilaT Apr 2015 #27

I can see both sides of it marym625 Apr 2015 #32

We do know that fracking can cause small earthquakes. SheilaT Apr 2015 #43

No, not directly but indirectly it becomes a "Possibly". Nihil Apr 2015 #44

Thank you marym625 May 2015 #60

I would think that the melting of all of that heavy ice MAY have an impact.. truebrit71 Apr 2015 #50

Me too marym625 May 2015 #55

I wouldn't discount it, but will leave it to the scientists. Cleita Apr 2015 #52

I agree marym625 May 2015 #56

Found a reference article Boomer May 2015 #54

That's quite a move! marym625 May 2015 #57

And now article specifically about Nepal's earthquake! Boomer May 2015 #61

This explains a lot.. cilla4progress May 2015 #63

That is interesting in itself marym625 May 2015 #64

My experience was there is no one cilla4progress May 2015 #67
