Was there a nuclear explosion during the Sichuan earthquake?

This interesting but unsubstantuated article suggests that there may have been a nuclear explosion during the Sichuan earthquake from one of China's underground military bases.

Boxun News, a Chinese-language Web site based outside China, reported that an unnamed expert has claimed that there was a nuclear explosion near the epicenter of the Sichuan earthquake, based on witness reports and the discovery of concrete rubble believed to have come from an underground military installation. The news of this nuclear explosion has raised questions about the cause of the earthquake.

Mr. He, a local resident, stated that when the earthquake occurred on May 12, people saw something erupt from the top of a mountain next to the valley, "It looked like toothpaste being squeezed out," said He. "No, it wasn't [magma]. It was these concrete pieces. The eruption lasted about three minutes."

According to a China News Services (CNS) report on May 31, 2008, paramedics from People's Liberation Army (PLA) hospitals and psychologists from Beijing onsite May 23 found concrete debris at the bottom of a valley near the epicenter. The half-mile-wide valley was covered with debris 10 - 20 inches thick, covering the valley floor for almost 1.5 miles.

No major construction was occurring in the area at the time of the earthquake.

The thickness of the concrete pieces seemed to match that used in China's underground military bases, according to Boxun's expert. He explained that while there are documented cases that earthquakes cause volcanic eruptions, there are no accounts of eruptions ejecting concrete.

Based on the CNS report and timing of the eruption at the scene, there seemed to be no evidence of natural volcanic activity. The expert stated he was certain a nuclear explosion shattered the underground concrete structures, hurling debris into the air.

At least one of China's nuclear military bases is located in Mianyang City, Sichuan, near the epicenter.

Chinese Internet surfers commented that right after the quake military Special Forces blocked traffic heading toward the epicenter on the mountain, and men in white chemical protective clothing in military vehicles were also spotted driving toward the mountain. Rescue personnel near the epicenter were all military, according to witnesses.

The expert believes the nuclear explosion was not confined to the underground test area and has caused radiation contamination, stating that in a call to Beijing he recommended authorities accept help from other countries, seal the area, find and provide help to those who had been exposed to contamination during the rescue work, and take emergency measures to prevent water contamination.

The expert believes that the nuclear explosion caused the recent 8.0 magnitude Sichuan earthquake in China. However, other experts referenced by Boxun withheld judgment as to whether the explosion caused the earthquake or the earthquake the explosion.

Wouldnt put it past the crazy Chinese military.

I wouldn't put it past the U.S. Military

Nasa scientists have said they could be on the verge of a breakthrough in their efforts to forecast earthquakes.

Researchers say they have found a close link between electrical disturbances on the edge of our atmosphere and impending quakes on the ground below.

Just such a signal was spotted in the days leading up to the recent devastating event in China.

They have teamed up with experts in the UK to investigate a possible space-based early warning system.

Many in the scientific community remain deeply sceptical about whether such signals are indeed indicators of an approaching earthquake.

But Minoru Freund, a physicist and director for advanced aerospace materials and devices at Nasa's Ames Research Center in California, told BBC News: "I do believe that we will be able to establish a clear correlation between certain earthquakes and certain pre-earthquake signals, in an unbiased way."
He added: "I am cautiously optimistic that we have good scientific data, and we are designing a series of experiments to verify our data."

Despite years of searching for earthquake precursors, there is currently no method to reliably predict the time of a future earthquake. Yet, most scientists agree that some form of early warning system could save tens of thousands of lives.

The ionosphere is distinguished from other layers of Earth's atmosphere because it is electrically charged through exposure to solar radiation.

On a significant number of occasions, satellites have picked up disturbances in this part of the atmosphere 100-600km above areas that have later been hit by earthquakes.

One of the most important of these is a fluctuation in the density of electrons and other electrically-charged particles in the ionosphere.

Early warning

One study looked at over 100 earthquakes with magnitudes of 5.0 or larger in Taiwan over several decades. The researchers found that almost all of the earthquakes down to a depth of about 35km were preceded by distinct electrical disturbances in the ionosphere.

The analysis was carried out by Jann-Yeng Liu, from the Center for Space and Remote Sensing Research in Chung-Li, Taiwan.

Though full details have yet to be released, the BBC understands that scientists also observed a "huge" signal in the ionosphere before the Magnitude 7.8 earthquake in China on 12 May.

The team at Nasa has also been working with Surrey Satellite Technology Limited (SSTL) in the UK, to investigate the feasibility of a satellite-based early warning system.

Stuart Eves, head of business development at the company, told BBC News: "The evidence suggests we're now crossing the boundary in terms of technology readiness."

He added: "What we don't know is how big the effect is and how long-lasting it is before the earthquake."

Minoru Freund believes other earthquake "precursors" could feed into this system. These include enhanced emission of infrared (IR) radiation from the earthquake epicentre, as well as anomalies in low-frequency electric and magnetic field data.

Rock 'batteries'

Minoru and his father Friedemann Freund, also from Nasa Ames Research Center, developed the scientific theory behind these earthquake precursors. It boils down to the idea that when rocks are compressed - as when tectonic plates shift - they act like batteries, producing electric currents.

"We now pretty much understand the solid-state physics of these rocks," Minoru added.

According to their theory, the charge carriers consist of a specific type of electron, called a phole, which can travel large distances in laboratory experiments.

When they travel to the surface of the Earth, the surface becomes positively charged. And this charge can be strong enough to affect the ionosphere, causing the disturbances documented by satellites.

When these pholes "recombine" at the surface of the Earth, they enter an excited state. They subsequently "de-excite" and emit mid-infrared light particles, or photons. This may explain the IR observations.

Dr Mike Blanpied, a geophysicist at the US Geological Survey (USGS), who is unconnected with the work told BBC News: "At this point, the connection between the laboratory phenomena and processes at work in the Earth has not been demonstrated and is the subject of research."

He has two principal criticisms of the work. Firstly, he said the experiments had been done on dry - or briefly soaked - rocks at room temperature and pressure. But deep in the crust, rocks have all their voids filled with mineral solutions and are subjected to high temperatures and pressures.

Secondly, he said, the researchers' hypothesis held that rapid changes in stress and strain in the crust began a few days before earthquakes.

Dr Blanpied, who is based in Reston, Virginia, said there had never been an observation of rapid strain changes before an earthquake, which meant precursor strains before earthquakes might be too small to have been detected.

Minoru Freund agrees that more work is needed to improve on the theory and some of the data. But he said he was planning to work up a proposal for a low-cost, space-borne early warning system based on at least three satellites.


The U.S. Military is heavily involved in manipulation of the ionosphere via super heating of the electrons and refractions of beams into the planet causing vibrations and increased pressures of enormous magnitude.

Its one thing to detect changes in the ionosphere and another to use it to create earthquakes.

If the compression of the rocks makes them produce electricity, which is then read in the ionosphere, you can hardly change the ionosphere to make an earthquake.

Its not a two way trip, one is conditional to the other.

Tut is talking about is something like the piezoelectric effect. That only works with some crystals. Which are very rarely found in the earth's crust. You cant send charge to the rocks back and forth. It makes no sense. The electrical resistance of the earth is just too high.

Even if this phenomena was possible it still doesnt add up as the forces generated during an earth quake are phenomenal, To dispel the charge you would have something equal to lightning from the ground up. More over its too simplistic to take as merely crushing of rocks, earthquakes have many different kind of waves like shear waves, transverse waves etc. The forces from each of them are different and so are their effects. Mechanically, earthquakes are a result of excess stress build up on the tectonic plates. The only way to "predict" earthquakes would be to calculate or estimate the stress potentials at the edges of the tectonic plates and keep calculating. Even then at best they would be able to provide probabilities, not an "early warning " system.

It would be akin to watching two sumo wrestlers locked in a grapple, by successive calculations you can give a probability of which person will slip first depending on weight, position and center of mass. Same with any early warning sensor.

The whole idea of the ionosphere getting charged sounds like hogwash. Before the ionosphere the effects should be most felt on the ground if this were really true.
