What do you think about the weight of the extra water from melting polar ice caps pressing on the ocean floor raising the continents? Maybe the whole thing is self-regulating. I don’t know enough to begin to prove it but it makes sense to me.

More arrogance from psuedo-scientists. We can control weather, we can cause earthquakes etc...If this is the case, wouldn’t undersea earthquakes be more frequent and massively more powerful than land based ones?

[Wuli]

i am not enough of an “earth science” student to know if the weight of the masses we are talking about are sufficient, or even could be sufficient, to have ANY affect on the movement of the fractured pieces of the Earth’s crust

i only believe the math for it must be simple,

if only the knowledge for that math was available (how do you find how much weight on the surface can be changed [added or taken away] before you alter ANY affect that such surface weight can have on the movement of pieces of the Earth’s crust)

but i also believe the knowledge and therefore the math models for it, are beyond current human scientific understanding - we don’t know if we can create Earth-surface changes, by weight, that can affect Earth crustal movements - i think???

i believe we do not understand what it would take

It seems to me that global warming can’t be all bad. It’s happened before and then oscillated back the other way enough times to suggest a self-correcting system. I’ve read that changes in albedo may have some effect. I was thinking the weight of the water might have some effect too.

There are a wide-variety of papers on reservoir-induced earthquakes in peer-reviewed journals.

It’s fairly well documented in actual events. None have remotely approached the size of this quake, and whether it’s true in this specific quake is open to question.

Actually, it’s more like “zee-peeng-poo”, but that’s hardly much better, LOL.

If anything, it should work the other way. The earth’s area is 1,809,557,368 square miles. Continents are about 30% of it, and about 25% of the continents are glaciated

Most of it is in Antarctica, Greenland, Alaska, and Canada. Asia has a small percentage of glaciers compared to its overall area. I roughly estimate 143,340,845 sqaure miles of glaciers, probably very high.

That goes into the surface area of the oceans 12 times, and the mass of the water is divided evenly everywhere. It might allow the areas that were under the glaciers to rise, but I don’t think the force would make much difference around the edges of the continents as we know them.

[LjubivojeRadosavljevic]

I find it odd that the earthquake would be triggered at a time when the reservoir level was low.

Issat right?....Well, I find it silly...that [Blah]

Sounds shaky to me.

Thanks for clearing that up.

The large San Francisco earthquake that occurred at the beginning of the last century was as the Crystal Springs reservoir was being filled South of the City. It sits directly on top of the San Andreas Fault. Could be coincidence or not.

Wuli ,there are places. Check rebound effects of glacial loading, Scandinavian, Great lakes, USA, United Kingdom, England The UK is sinking in the south and rising in the north, the entire Island. This was caused by 10,000 feet of ice melting 20,000 years ago. Basalt, granite expands .1%[percent] when relieved of surrounding pressure,like after being deeply buried. It sheets like an onion. You can tell how deep the granite was buried by the thickness of the sheeting action I notice that clowns and Idiots run off there mouths even on this serious site: even though we are talking about thousands of deaths of innocent people caused by wrong decisions by man. I have studied earth science for 34 years and can tell you some facts about what caused the earthquake 1] The placement of the dam and the weight of the water was a bad decision. It lubricated the fault and caused the simi-plastic mantle material under the lake ,deep down to push under the crust ,raising the crust at the edges of the lake. 2] The Gps stations, 1000's in China, all of them, all record the turning to the South- East of the entire "high continent", at the China line. Thats right the High continent of Asia is being forced south toward Planet earths Equator. Albert Einstein, said place a hugh asymmetric load [like the high continent of Asia] on the surface and the weight will force the crust sliding on the semi-plastic mantle below toward the Equator. The movement will be less then 4 inches per year. The reason: Check the GPSS illustrations. India, is pushing northeast, moving the entire hymillian plateau to the northeast, but once you check the gps stations in China the movement of the crust turns south east. The result is ripping the crust, faults, earthquakes ,sections of the crust rise ,fall, spin, tilt- everything that happened in the big dec 26 2004 Indoniesian earthquake could happen along this line. Most earthquakes 95% happen 4,000 to 6,500 miles from two pivot points. Botswanna South Africe ,and the Hawaiian Islands ,opposite each other. [called Antipodal] This is caused by true polar wandering - which I verified in 1976 with the principal scientist of the Smithsonian Institute . The earths crust slides over the interior at 4 inches per year. When Large ice shells existed 900 million years ago and moved on the surface the crust slid 6 inches per year then. The Chandler Wobble: The Mid-point of the 14 month cycles of the Chandler wobble over the last 100 years show movement toward the west four [4] inches per year. The crust of the planet is moving over the axis of rotation today from the 90 degree west longitude line over the top to the 90 degree east longitude heading toward the Great lakes. The pivot points are important. John delano Delano's Discovery-lulu.com 38 old sylvan lake road hopewell jct ny 12533 845- 223-3687 sunnyday1@optonline.net

again

I am not doubting that the weight of ANYTHING, made by nature or made by man, sitting on the crust of the earth CAN - IF SUFFICIENT- affect the timing and direction of major movements (slippages/seismic events) of the crust in the specific areas that may be affected by said weights.

What I questioned was whether or not we have a precision of knowledge and data with which to apply a mathematical theorem/algorithm that can explain exactly what amount of weight (x) has what degree of affect (y); and eventually, and with even greater accuracy of predictability - in a given area (a) at a given time (b).

I am not saying that there is no general theory that believes such weights can/are/do/will have the affects we are talking about, only that, I believe we cannot verify the accuracy of the idea with mathematical precision, in spite of apparent supporting anecdotal justification.

What about the movement of a significant amount of mass from the ice sheets to a more even distribution? I do know that even a small amount of mass shed from a finely balanced machine will introduce wobble or other instabilities. Couple this with the uneven distribution of continental masses and place the whole mess on a semi-liquid sea of magma. It seems to me that if you change the push downward in one place enough there can be significant changes in other places.

Wuli did a good job discounting my concerns in an earlier post but I still have questions..

BTW, Wuli, I don’t mean to discount your post. It was very educational and I appreciate you taking the time to explain things.
