Anomalous Concentration of Methane Vents Discovered at the Northern Cascadia Margin

"Off the coast of Washington, columns of bubbles rise from the seafloor, as if evidence of a sleeping dragon lying below.
But these bubbles are methane that is squeezed out of sediment and rises up through the water. The locations where they emerge provide important clues to what will happen during a major offshore earthquake."

The first large-scale analysis of these gas emissions along Washington’s coast finds more than 1,700 bubble plumes, primarily clustered in a north-south band about 30 miles (50 kilometers) from the coast.

Scientists found the first methane vents on the Washington margin in 2009, and thought at the time they were lucky to find them. But since then, the number has just grown exponentially.

Results show, the gas and fluid rise through faults generated by the motion of geologic plates that produce major offshore earthquakes in the Pacific Northwest.

The authors analyzed data from multiple research cruises over the past decade that use modern sonar technology to map the seafloor. Their new results show more than 1,778 methane bubble plumes issuing from the waters off Washington State, grouped into 491 clusters.

The vast majority of the newly observed methane plume sites are located at the seaward side of the continental shelf, at about 160 meters water depth.

Those seismic surveys over the areas with methane emission indicate that the continental shelf edge gets thrust westward during a large megathrust, or magnitude-9, earthquake. Faults at this tectonic boundary provide the permeable pathways for methane gas and warm fluid to escape from deep within the sediments.

The study, from the University of Washington and Oregon State University, was published in the Journal of Geophysical Research: Solid Earth:

Anomalous Concentration of Methane Emissions at the Continental Shelf Edge of the Northern Cascadia Margin

"A model of enhanced sediment permeability arising from a contrasting response between the inner and outer portions of the accretionary wedge deformation during a megathrust earthquake cycle appears the most likely mechanism. This faulting is generated during extension of the overriding plate during megathrust earthquake cycles, with semicontinuous permeability enhancement of the fluid pathways from excitation by contemporary incident seismic waves."

It's not a wonder. If at one time the Juan de fuca plate was forested land, all that biomatter decayed and has to go somewhere in subduction.
Something that crosses my mind is we do not have human history for large fast earth changes. There may be much more to atlantis than a mythical story.
Inundation on a continental scale might be fodder for the noah mythos as well. Not sure if there is a similar theme in gargamel.

There is ample proof the earth flooded as described.
Right now they are placing more and more sensors to moderate activity because a couple of guys have used all available information showing that there is a gap, a hole, along the Juan de Fuca wherein it is being subducted under the North American and they have proved it. There is a current article I will have to find the link for yo might life? Along this location they have discovered rhyolitic as well as basaltic rock formations which indicated even stranger things dealing with the volcanoes located in southern Oregon that resemble Yellowstone in the magmetic deposits.

Nice...once that all escapes s massive sinkhole will form. Bye bye California.

Capture the methane, compress and liquify it, then run civilization on it cleanly, forever...

Methane vs Propane

Methane and Propane are the first and the third members of the alkane family. Their molecular formulae are CH4 and C3H8 respectively. The key difference between Methane and Propane is their chemical structure; Methane contains only one carbon atom and four hydrogen atoms whereas Propane contains three carbon atoms with eight hydrogen atoms. Their chemical and physical properties vary due to this difference.

It's a subduction zone so the gas generated has to vent somewhere...better there than Mt. Ranier Or Mt. St. Helens

There is an underwater volcano 300 off the coast of Oregon. The Axial Seamount is very much alive and they are trying to predict when it will erupt again. Last eruption was in 2015.

Good page for current info:

I believe this part of it is in Oregon.

Yes, and there are more of them off of Monterey too. Many more than we have an idea abut. And methane, all over the Pacific they have been boring the sea floor and finding methane.

Large earthquakes generate infrasound up to 9 days before they occur. They are inaudible to humans but animals can hear them. Watch the activity of pets and wild animals, they will give warning.
