ZetaTalk: Tunguska Explosion
Note: written on Feb 15, 1996.

A source of endless speculation is the wide area of flattened trees, spread outward in a circle, the result of an apparent explosion that occurred just after the turn of the century in Siberia. No witnesses, radioactivity, or meteor remains seem to exist as pieces toward solving this puzzle. Nuclear power was not yet in mankind's hands. What occurred? The Tunguska trees are devastated by an explosion that occurred close to the ground, as evidenced by the butterfly pattern of trees knocked sideways. It was a huge cloud of well mixed methane and air, equivalent to all the natural gas being piped about in the US at any given time, and the burn spread around this cloud or that, under and over and around, until a particular pocket of well mixed methane and air had no where to go with its heat since the burn was all around. Itself burning, the heat ramped the combustion up to the explosion level.

Methane gas occurs naturally, a result of the decomposition of organic materials. Landfills must vent this or experience explosions. Some humans know they can light and briefly burn their farts. Humus or accidentally buried organic material is a source of methane gas, and if not vented, this attempts to rise, being light, and will pool if trapped. Siberia was once lush, a fact the carcasses of mastodons reveal, as their bellies are full of grass. Flash frozen and covered with volcanic dust, organic material lies as a potential. Where Siberia may appear to be a frozen wasteland, the center of the Earth is hot, and decomposition of trapped matter, proceeding slowly but over a long time, can accumulate a large, trapped pool of methane gas. Released Due to a Shift in the Earth's crust and encountering a raise in temperature sufficient to act as a spark, this would explode, with the size of the explosion in proportion to the volume of violently venting gas.

The burn was lit by the wick traveling back along the wisp of methane that had been blow up and southwest by the prevailing westerlies over Siberia. What witnesses saw was the burn off of methane that had disbursed into the air and was not sandwiched between burning masses so that its heat had nowhere to go, the basis of exploding, rather than burning, gas bombs. The process was:

1. Methane gas hisses out from under frozen permafrost that had been cracked like a sheet of glass due to earth stress, pre-shock to the earthquake that was recorded during the Tunguska explosion.
2. Methane gas mixes with the air as it rises, followed by more hissing air, so that a huge cloud of methane has formed in the atmosphere over Tunguska, equivalent to all the natural gas at any given time in the US.
3. A wick of methane that has drifted upward and southeast, driven by the prevailing westerlies, is sparked due to the air movement, the same process that causes lighting due to rapid air movement during storms.
4. The lit methane burns rapidly back along the wick, the "meteor" that was seen, lights all the gas that is encountered but before all but the nearest witnesses can see it, those who died in the explosion, an overburn over gasses closer to the surface prevents heat from rising and an explosive situation occurs.

The explanation that a meteor exploded above ground is an attempt by the establishment to avoid the methane gas, and thus the pole shift and shifting crust issue. Comets and meteors do not explode when encountering Earth’s atmosphere. This is not what your history or science presents to you! If they are monstrous, they plunge to Earth and leave a crater such as the Gulf of Mexico off Yucatan. If they are tiny, they burn up in the atmosphere as shooting stars. If they are midsized, they burn on their periphery but land to be rocks picked up and examined by your scientists. The lack of meteor particles or dust proves that it was not an exploding meteor. Methane, once burned or disbursed into the air, leaves no trace. Meteors leave traces, methane does not.
