I posted this in another thread, it puts the potential destruction into perspective.
ok. here is some research I put together, maybe some of you can figure out what I am trying to convey.

Butane and propane in their natural states are gases at room temperature, but they are normally compressed into liquids for everyday use. This is done so that the butane or propane can be easily transported and used, since in their gaseous state they take up a much larger volume. Both are readily flammable. Butane is used in cigarette lighters and has a flash point of -76 to -117 degrees Fahrenheit. Propane is commonly used with barbecues and has a flash point of -156 degrees.
Now we know there is 1.5 million barrels of liquid butane in a salt dome near the sink hole and apprently that going off would equal 5.8 trillion BTUs. source [link to sincedutch.wordpress.com

Lets do the math to get an idea how many BTUs are in a barrel of liquid butane and we'll go the conservative route and use the LHV or low heating value. 1 barrel contains 3,906,000 BTUs. Times that by 1.5 million barrels and we get 5,859,000,000,000 or 5.859 trillion BTUs. Granted liquid butane is a flammable liquid and not a combustible liquid, this is still a massive amount of energy. More so it is encapuslated in a cavern under pressure. If this were to be sparked, it would be very very bad. That would be equal to a 1.477431223829 megatons (source of conversion- [link to online.unitconverterpro.com
The Hiroshima bomb was .02 megaton or 20 kilotons. However modern nuclear weapons are around 1 megaton, the idea is you can do more damage with 10 1 megaton weapons then 1 10 megaton weapon. Um, It doesn't take a math genius to see that if this cavern containing this liquid butane were to be ignited, it will be very very very bad. It's 1 thing for liquid butane to be ignited in open air as compared to being in a compressed environment with what I expect to be butane in gas form near the top and think of the immense pressures involved in containing this stuff. Think of it like a fire cracker, if you rest it on an open hand, it'll burn you, hold it in a fist and buh bye hand, you'll get the name "captain hook". This is not good at all. Whoever thought it was a good idea to contain anything like this, including toxic waste and radiological material in caverns inside the earth is a fucking retard.
