The Aliso Canyon gas well blowout was the largest methane leak in U.S. history, releasing over 90,000 tonnes (100,000 tons) of gas into the air.
It belched methane into the sky over Los Angeles for 16 weeks straight until it was finally plugged on February 11.
Now, a new worry, this time stretching the length of the San Andreas Fault line.
On February 27th enormous amounts of Carbon Monoxide leaked into the atmosphere along the West coast of America see above...it's the amount of Carbon Monoxide which is simply stunning.
It is well understood that large amounts of Carbon Monoxide is released into the atmosphere before an earthquake, however the amount of Carbon Monoxide release on the 27th of Feb is as far as I can tell unprecedented.
As of today most of the Carbon Monoxide has dissipated but large amounts remain, see below..
This release of Carbon Monoxide could be an indication of an imminent major quake along the volatile San Andreas Fault
The San Andreas Fault is a continental transform fault that extends roughly 1300 km (810 miles) through California.
It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal).
The fault divides into three segments, each with different characteristics and a different degree of earthquake risk, the most significant being the southern segment, which passes within about 35 miles of Los Angeles. Wikipepia.
Carbon Monoxide is known as the silent killer as it has no smell and is lethal within minutes, it would be interesting to know if this Carbon Monoxide is also leaking into the Pacific which could account for the many marine life die-off which is affecting the West coast
