[quote:Anonymous Coward 21195063:MV8xOTUxNjAzXzMyNzE2MTgzXzczNzFGMkYy] http://www.examiner.com/article/bayou-corne-disaster-extra-security-called-methane-bubble-tsunami-revisited less than 50% posting for those who haven't read this: [i]Two years ago, after BP's Deepwater Horizon catastrophe began, scientists observed methane concentrations in the Gulf up to 10,000 times higher than normal and corresponding oxygen depletion levels. Methane is a greenhouse gas 20 times more potent than carbon dioxide. Two years ago, residents along the Gulf reported the water "bubbling" and "hissing." For two months, Bayou Corne area residents have been reporting their swampland bubbling and a diesel odor. Early warnings after the Gulf catastrophe began were that high temperature oil gushing from the rupture could melt the methane hydrates (clathrates) at the ocean bottom, leading to massive methane release to the surface. Methane at such a profound depth would be under thousands of pounds of pressure, like fracking fluid injected into deep gas wells to fracture the gas-bearing strata, releasing the gas for extraction. If any of the melted methane at the ocean bottom has access to strata which could also fracture, could it travel horizontally underground for some distance, to surface miles away? In “The Worst-Case Scenario,” a frightening "low-probability" scenario was described on Huffington Post by DK Matai, Chairman of Asymmetric Threats Contingency Alliance (ATCA) & The Philanthropia. Matai highlighted the possibility of the "massive bubble trapped for thousands of years under the Gulf of Mexico sea floor" exploding and setting off a "tsunami [traveling] at a high speed of hundreds of miles per hour." "There are serial resistances along channels, say along stata or their boundaries; transverse resistances between channels; and transverse capacitances which are voids where gas can be stored at applied pressures," retired neuroscientist Paul Brown explained to Deborah Dupré Saturday. "In the case of a long-lasting increase of source pressure due to an undersea rupture, as the gas travels along the longitudinal channels, pressure buildup is slower and slower at greater and greater distances.[/i] [/quote]
The initially estimated 200 by 200 feet sinkhole that developed late last week, swallowing ancient cypress trees 100 feet tall near Bayou Corne and Grand Bayou communities in south Louisiana, is now reported to be 380 feet deep with a diameter of 372 feet, filled mainly with salt water with traces of diesel fuel, and only 1,500 feet from a cavern filled with butane, according to Tuesday morning news. Analysts' reports further hint that Texas Brine Company's cavern failed, but the butane cavern failing is today's worst-case scenario.
If a nearby butane-filled cavern fails, as it appears the brine cavern did,
"it could cause an explosion felt up to two miles away."
