How does "global warming" cause earth quakes?

Question

In a previous question someone answered that global warming would cause more earth quakes. Twisters and tropical storms, okay I can buy that, but quakes...WTF? Someone explain this to me please.

Answer 1

There's no evidence that global warming has caused (or will cause) any earthquakes. There is, however, some speculation that as massive glaciers melt (from global warming) the pressure on the underlying faults will change and that could be a factor in earthquakes.

Answer 2

If you want to blame anything at all on global warming, go ahead; even your pimples.  It ain't true, but global warming if it existed wouldn't care anyhow.

Answer 3

It doesn't.

Answer 4

It's possible, but not the usual seismic earthquakes caused by plate movement. What can happen is that, the crust is fairly 'springy' in places. As glaciers and ice sheets melt and the water flows elsewhere, the weight pressing down on the crust in that area decreases, causing the crust to move upwards. If this happens in a jolt, an earthquake will occur.

Answer 5

I want to say it doesn't, but I can't be sure about that.

The only thing I can imagine is this:

For example, as the ice melts on Mt. Everest, it the earth beneath is less compact and so the Mountain as a whole is growing some.

If things associated with global warming, such as the melting of ice, cause the ground to change some, I guess it's plausible that this could ultimately make the tectonic plates less pressured and therefore more likely to shift.

I decided to do a little google work, and the scientists in the site below agree with me...who knew I was a scientist...

lol, I hope this helps

Answer 6

Anthropogenic plate tectonics is the result of anthropogenic global warming inducing thermal loads in the Earth's crust.   In anisotropic materials the total volumetric expansion is distributed unequally among the three axes and if the symmetry is monoclinic or triclinic even the angles between these axes are subject to thermal changes. In such cases it is necessary to treat thermal expansion as a tensor that has up to six independent elements. A good way to determine the elements of the tensor is to study the expansion by powder diffraction. All parts of the crust and all bodies of water have a coefficient of volumetric thermal expansion β, it is on the order of 10exp-7 for hard solids to 10exp-3 for organic liquids.  As the volumes expand, due only to anthropogenic CO2 emissions, large stresses build up on the tectonic plate boundaries.  These stresses are released in a massive quake and/or a Tsunami. In the absence of a tectonic plate boundary, a plateau or flood plain, can, in fact, develop a massive geodynamic zit....like Mt St. Helens-only much bigger.   As we all know, that sort of monkey business never happened before the Carter years. F'tang f'tang, bwwwaaaah.  Now, if you send me $.10 for every gallon of gas you use, I'll set up a futures market and send you a convertible anthropogenic plate tectonic offset coupon.  You can amuse your friends with it.  Money for nuttin' and the chicks are for free........

Answer 7

NO relationship at all.

Answer 8

In order to answer the question we'd have to assume that "global warming" is more than just an elaborate hoax dreamed up to create "new industry".

If we're going to credit Global Warming with earthquakes why not credit leprechaun's for the Gold Rush.

Sorry, I just don't buy into the whole Global Warming myth.  I believe the earth goes through cycles, and, YES, there is a good chance that tornados, earthquakes, etc., are the earth's way of 'correcting' herself.
