‘Large
release’ of methane off Los Angeles coast: gas could be from shift
in tectonic plates
6
March, 2013
Authorities
say a foul odor that spurred calls to fire departments throughout the
city on Sunday is possibly the result of the large release of methane
in the Santa Monica Bay.
Santa
Monica Fire said in a department statement that they believe the
strong odor was caused by a naturally occurring methane leak below
the ocean floor.
“This
morning there was a large release of natural ocean floor methane
released in the Santa Monica Bay,” the statement said. Brian
Humphrey, a spokesman for the Los Angeles City Fire Department, said
the odor was noted inland from the Santa Monica Bay. Santa Monica
fire haz-mat crews detected rather unusual concentrations of odorless
methane gas in the air that they believed to be coming from either a
patch of pungent algae, or a sulfurous gas-laced methane bubble, said
a dispatcher.
That
may night be the case; however. Sam Atwood, a spokesman for the Air
Quality Management District (AQMD), said his agency has not confirmed
the Santa Monica Fire Department’s theory. Authorities said that
recent changes in water temperature may have caused plankton and
algae beds to bloom, releasing methane just below the surface.
The
gas also might have been produced by a geologic event, such as a
shift in tectonic plates. Officials believe either a pocket of stinky
algae, or a bubble of methane laced with sulfurous gas, surfaced in
the ocean.
