La. sinkhole methane explosion possible says sheriff, refuting naysayers:
The Assumption Parish sheriff stated that methane ignition and explosion are possible in the Bayou Corne sinkhole area, refuting naysayers about such an explosion and spotlighting grave human rights issues related to the "history-making event" and "environmental nightmare,’ according to a KLFY Channel 10 three-part special televised report aired Friday.
The possibility exists that Louisiana's sinkhole-related methane, percolating in over a dozen sites near and miles away from the sinkhole area, could ignite and cause an explosion, according to Assumption Parish Sherriff Michael J. Waguespack, interviewed about the unprecedented Bayou Corne event unfolding in South Louisiana's swampland.
Waguespack, lover of south Louisiana people and culture, made the statement to KLFY reporter Chuck Huebner about the massive amount of methane known to be trapped below the Assumption Parish sinkhole area surface, continually leaking and bubbling to the surface.
