43. We do know that fracking can cause small earthquakes.

But the Richter scale is a logarithmic one, and every decimal point increase, is a ten-fold increase in power. So a 7.1 is ten times as powerful as a 7.0, and an 8.0 is one thousand times as strong as a 7.0.

There are those on this board who have been through earthquakes, and their input could be helpful. The only time I was in an earthquake I actually slept through it, although in my defense it was a five point something aftershock of the Northridge quake in 1994. I do know that others in my hotel were awakened by it.

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

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

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

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

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

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

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

I agree marym625 May 2015 #56
