General BS forum I guess anything is fair game in here. Just watch the subject matter doesn't get carried away too much. |

....and now we know why. Our government's doing it!

SECRET UNDERWATER ATOMIC EXPERIMENTS
Another popular theory is that the United States government is secretly testing atomic weapons underwater (both for safety and intelligence reasons) and that the explosions created by these tests may have affected the tectonic plates leading to the earthquake in Japan. Versions of this theory have actually been around for a few decades and they have some basis in fact. From 1945-1992, the U.S. did conduct numerous underwater tests of nuclear devices.
There has been past evidence that underwater nuclear testing has caused landslides (like in Mururoa in 1979), which can in turn trigger a tsunami. But whether or not such testing could cause an earthquake of this magnitude or whether anyone was even doing any sort of atomic testing at all is speculation. But if our government were indeed conducting such tests, it raises another question for the conspiracists…was it an intentional ploy to trigger the earthquake and/or tsunami? Which leads to the final theory—
WE INTENTIONALLY CAUSED THE QUAKE TO LOWER OIL PRICES
I’m sure everyone who drives a car has noticed the sharp rise in gas prices recently. And sure enough, after the earthquake, oil prices dropped below $100 a barrel. Some economists are saying this disaster is “good” for business as Japan’s need to reach out to other friendly countries to help rebuild will benefit the United States. Which means there are those who believe that if a disaster like an earthquake is going to help bring down oil prices and stimulate our economy, they’re not going to put it past our powers-that-be to create that disaster themselves. But how does one exactly create an earthquake of that magnitude?
Enter HAARP a.k.a. the High Frequency Active Auroral Research Program. Based in Alaska and funded, in part, by the U.S. Air Force and Navy, HAARP is an ionspheric research program that exists to develop enhanced technology for radio communications and surveillance. HAARP is also sort of the lesser-known cousin to Area 51 and a whole web of conspiracy theories have blossomed over the years around the facility. And what are some of the things HAARP is allegedly responsible for besides this recent earthquake? Well, last year’s Haiti earthquake, the downing of TWA Flight 800, the Gulf war syndrome and other disasters worldwide. Damn, someone alert Charlie Sheen.

I guess I don't understand what sort of testing of nuclear weapons still needs to be done. The US has had them for what, 70 years? And as a weapon, they have actually been used HOW many times? Has the point of diminishing returns in expense and development been reached yet for what can be expected to get out of them?

Yeah... You do have to wonder what effects that released radiation will have to the environment even though the tests are done underground. But I guess us poor saps are expendable in the big scheme of things.
So would this be considered as yet another conspiracy thinking that all that radiation just might not be doing us any good?
And you do have to wonder what the pounding of those bombs might be doing to the earth itself.
And no, I don't think those nuclear weapons are at ALL cheap.

Underground tests in the United States continued until 1992 (its last nuclear testing), the Soviet Union in 1990, the United Kingdom in 1991, and both China and France in 1996

So the Earth is supposed to be 4.5 billion years old. Seriously, why is the crust of this planet STILL unstable?

Apparently, at least according to This Article, not a whole lot. At least, not in the sense that they cause what fits into the conventional definition of an earthquake. Although they do cause seismic activity which is apparently very analogous to 'natural earthquakes'.
Quote:
There was an earthquake in Afghanistan in March 2002. Coincidentally, there was a lot of bombing going on. Or was it coincidence? Many people ask, Do aerial bombardments cause quakes? Scientists immediately say No. First of all, they don't like the word "cause."
An earthquake is the sudden release of strain energy in the Earth's crust (see "Earthquakes in a Nutshell"), but strain builds up from several different causes: the movements of plate tectonics, the weight of sediments shifting from erosion or from deposition, changes in fluids underground, and more obscure factors like mineral phase changes in the mantle (see "Deep Earthquakes"). They all add up, and we can't single out one of them as the cause. Scientists prefer to talk about what might trigger or induce an earthquake.
Do Bombs Induce Quakes?
OK, then, let's ask again. Did the bombing induce the quake? From a century of experience, we can confidently answer No. Some human activities do induce earthquakes, but not bombing like that in Afghanistan.
The question is easy to test: just look at the seismic record and see if earthquakes increase after episodes of bombing. Unfortunately, there has been plenty of bombing in the last hundred years. Fortunately, seismologists have monitored earthquakes for that whole century. No increase in quakes—not even little ones—follows bombing campaigns.
Some authorities have tried to blame quakes on bombs. After the 31 May 1970 Peruvian earthquake (still remembered for the deadly landslide it triggered from the mountain Huascarán), the Peruvian government accused the French of setting it off with their atomic tests in Mururoa Atoll, all the way across the Pacific. Peruvian scientists at the multinational research agency CERESIS responded in the press that this was nonsense.
There are other short-period natural mechanisms that you could compare with bombing: stresses from the tides, storm winds blowing against mountain ranges, landslides, volcanic eruptions and the shaking of nearby earthquakes. Those mechanisms involve a great deal more energy than bombing, and they're more coherent—less random.
None of those correlate with earthquakes either, with one uncommon exception: sometimes a large earthquake can trigger smaller ones at a distance. The 1992 Landers quake was the first clear example, and that was a large event, magnitude 7.3. The 2002 Denali earthquake in Alaska, magnitude 7.9, triggered events thousands of kilometers away at Yellowstone in Wyoming.
So the forces that ordinary bombs exert don't cause earthquakes. The amount of energy in bomb explosions is microscopic compared to the energies of earthquakes. It's like the difference between playing on a piano and dropping the piano down a flight of stairs.
Can Humans Induce Earthquakes at All?
We do have some good examples of human activities causing triggered quakes. It takes years of concerted effort, but they happen.
One type of induced quake occurs where fluids are pumped out of or into the ground. Oil-producing districts, for example, or areas where toxic wastewater is pumped into deep disposal wells experience small shocks that are sometimes strong enough to feel.
Another type happens where new water reservoirs are created. The first famous example was after the Hoover Dam created Lake Mead in southern Nevada. Hundreds of local earthquakes, some up to magnitude 5, happened in the decade after 1934.
Underground mines disrupt the natural stress state of underground rocks. The wall of a mine passage has all the weight of the rock above it pressing down, but no weight on the open side. Sometimes the wall bursts from the strain, spraying the passage with rock bits and destroying anything nearby.
Seismograph records of rock bursts look much like earthquakes. The largest known rock burst happened in a German potash mine in 1989 and had a magnitude of 5.7. It demolished the mine openings and damaged most of the town of Volkershausen.
Another kind of mining-induced quake happens as the ground subsides into the mined-out space. These are smaller, gentler events than rock bursts. But when large open spaces are mined out, the energy involved in a ceiling collapse can be substantial. The "mountain bump" that destroyed the Crandall Canyon coal mine in Utah on 6 August 2007 reached magnitude 3.9.
All of these types of human-induced seismicity happen from long-term changes in the underground stress field, not the brief, tiny stresses from bomb explosions.
OK, what about nuclear explosions? Well, they indeed cause earthquakes—that is, they are earthquakes, releases of energy that are felt as shaking and recorded by seismographs around the world. But not even the largest bomb test has ever induced a natural earthquake. (The Berkeley Seismological Laboratory explains more.)
PS: Like natural earthquakes, underground nuclear tests have aftershocks. We know this because they act like aftershocks: they are smaller than the main event, cluster around its location, and decrease as time passes. Also, the largest bomb tests have the same magnitude as moderate earthquakes, and their aftershocks are smaller by a full unit of magnitude (that is, they obey Båth's law), just like natural aftershocks.

Found This Article, which touches on your question. It offers the following theory:
Quote:
Free water and stagnant lids
One theory being investigated is the idea that Earth is unique due to the presence of free water on the planet surface.
“Water lubricates the fault lines and helps rock masses glide, which allows an active overturning of the Earth’s crust,” she says. “But, since we’ve seen evidence that Mars once had free water, it raises more questions … there must be a lot more to it than just this. We may be missing some aspects.”
Other solar bodies do show variations of Earth’s tectonic plate and convection system, she reports. For example, Mars and some asteroid bodies have a “stagnant lid” design where hot rock can churn deep inside the planet but nothing seems to happen at the surface.
Venus is speculated to perhaps have an “episodic overturn” model where the entire planet surface crumbles and sinks down into the interior while massive amounts of magma rise to the surface to replace it. In either case, the processes continue until the celestial body has used up all of its energy and eventually “dies.”

Apparently, Earth may not be quite so unique as was once thought. As of last year, a US geologist found evidence of tectonic movement on Mars, albeit it of a much more 'primitive' nature.

Yin made use of high-resolution images taken by several Mars orbiters, including NASA's Mars Odyssey and Mars Reconnaissance Orbiter. He focused particularly on the southern region of Valles Marineris, where a 2400-km-long trough connects three large canyons: the Ius, Melas and Coprates Chasmata. He painstakingly trawled through these images to look for "kinematic indicators" on the Martian surface – marks that reveal how the crust has moved. He discovered faults in the Ius Melas Coprates trough with a consistent, slanted orientation, which indicates a horizontal, shearing motion. He also noticed "headless" landslips at the bottom of the trough – that is, landslips without any traceable source, possibly caused by a horizontal movement of the crust since the landslips occurred.
Furthermore, Valles Marineris is exceptionally long and straight. "On Earth, there is only one kind of fault that can make a very straight and linear trace," says Yin, "and that's a 'strike-slip' fault – a fault that's moving horizontally over a very large distance." He also adds that the rocks on both sides of Valles Marineris are extremely flat, whereas rocks near a rift tend to be tilted.
