America's West Coast

Sediment deposited by Lake Missoula with a hammer for scale.

Awed by majestic landscapes they passed when blazing a trail through the American West to the Pacific Ocean, the Lewis and Clark expedition possessed no science to explain the terrain that marveled their senses in 1804 were crafted with extreme earth changes. Mega quakes estimated as large as 9.0 magnitude periodically shake the West Coast along with large tsunamis that inundate it. See Great Earthquakes of the Pacific Northwest.

Lewis and Clark crossed the floodlines where Glacial Lake Missoula literally tore bedrock from mountains as flood waters traveled an estimated 65 miles an hour, rushing through Montana, Idaho and Washington into Oregon, when blocked glacial melt repeatedly broke through ice dams 15,000 to 10,000 years ago. See video of smaller-scale glacial flooding that continues with global warming.

A dominant faction in the nineteenth century, Christians commonly believed America was the Promised Land their God had given them to take and steadily displaced Native Americans to remake America in the image of Europe with an elite class of new-money aristocrats in the guise of robber barons, proclaiming the federal doctrine of Manifest Destiny. Many illiterate immigrants to America had never seen a book except the Bible and were not able to assimilate its founding ideals that guaranteed freedom for all religions. The European look-alike nation they built is physically and ethically sinking. (A search of Google for the very important federal doctrine of Manifest Destiny pulled up 317,000 references on July 3, 2016.) See article on Manifest Destiny.

When geologist Harlan Bretz announced in 1923 that the potholes in basalt bedrock and scablands of Washington State had been created by massive flooding at the end of the last glacial age, his largely Christian brothers and sisters fought his science tooth and nail. Many believed the world had been created circa 4,004 BCE and did not conceive the Earth had existed 20,000 years ago when global temperatures began warming and melting glaciers. See Ussher's chronology of the world, formulated in the seventeenth century by Archbishop of the Church of Ireland (Armagh) with a literal reading of the Bible. "Ussher deduced that the first day of creation began at nightfall on Saturday, October 22, 4004 BC . . ."  Like many pioneers, Bretz's science was widely accepted and expanded after his death in 1981 with evidence of similar flooding in Scotland and Turkey to show virtual global flooding at the end of the glacial age. See video about Glacial Lake Missoula. But this outlines only a social component that deeply influenced how the West Coast was settled, while the geology continues to pose a profoundly changing landscape in the twenty-first century.

Much of the Promised Land is subsiding now and will sink beneath flooding waters from the Pacific Ocean before the twenty-third century. Anticipating a mega quake as large as 9.0 magnitude, Federal Emergency Management Agency (FEMA) conducted drills in Washington and Oregon in June 2016. FEMA expects as many as 13,000 people will be killed and another 27,000 injured in the mega quake that will cause much of Washington State to literally drop down closer to sea level. See video about the Cascadia fault zone in Washington.

So many earthquakes were focused in Oregon, that the U.S Geological Survey (USGS) issued a special report on the Scott's Mills Series in the year following a prophetic crop circle at Kennewick, Washington. See article about Scott's Mills Series. Longitude 119° West that extends from Kennewick, Washington through Northridge, California has been continually active with earthquakes since May 1993, when a crop circle depicting the Earth's magnetic core formed at Kennewick. The Mammoth Mountain super volcano stretches across 119° West longitude, and magma from the Yellowstone volcano migrated into California throughout 2014, with two consecutive eclipses directly affecting the western triangle. After the March 11, 2011 9.0 magnitude megaquake epicentered at Honshu, Japan, an underwater volcano erupted in the zone on the Juan de Fuca Plate the Butte, Nebraska crop circle had pinpointed. See Butte, Nebraska crop circle and measures.

Mt. Lassen in California has started subsiding and volcanologists are not sure why but posit it results from plate movement. See report on Mt. Lassen. Magma movement on the West Coast in the area noted with red lines on the below map began increasing in March 2011, after the 9.0 magnitude quake that crippled three nuclear reactors at Fukushima in Japan. Growing pressure on the Juan de Fuca Plate, which is subducting under the North American Plate, could account for this pressurizing effect on volcanoes.

Subject: [TimeStar] Magma rising at Mammoth Mountain volcano

Magma began rising at Mammoth Mountain as soon as the TimeStar window opened on the area January 30.  Things will get very active on the USA’s West Coast through July, because the last lunar eclipse was connected to this area.  Best regards, Krsanna

Magmatic intrusion in Mammoth Mountain, Long Valley, California

by ROBERT on FEBRUARY 15, 2014 · 9 COMMENTS
  
A number of earthquakes shake the mountain.

In California there has been a quake swarm at Mammoth mountain that has been going for more than a week. No Eruption yet, but plenty of quakes.
California’s Long Valley caldera, near Mammoth Mountain,  is the largest super volcano on the planet, says Alessandro Decet. In the last week it has recorded a few earthquakes, with the most intense a magnitude 3.0. Since everything is still mild in intensity, no alarm or status change was issued. However, the earthquakes are increasingly shallow, signaling that magma may be about to get closer to the surface.

Yellowstone is specifically named in TimeStar predictions for January 30 through February 25, and quake sprees at the volcano are common during periods of this glyph.  As a trend since 2011, magma is moving more actively at Mammoth Mountain volcano in California, which is also in the area for the glyph. I did not post about Yellowstone volcano, thus saving wear and tear on nerves.   

Magma movement has been more active at Mammoth Mountain than at Yellowstone.  Please note that the die-off of 100,000 fish in January was on 119 West longitude due north of Mammoth Mountain, where magma is moving and a 1 Hz “noise” is developing west of the 112 West longitude indicated in the TimeStar prediction.

Tohoku grim reminder of potential for Pacific Northwest megaquake

College of Science geophysicist John Anderson presents study at science conference in Vancouver, B.C.

The March 11, 2011 Tohoku earthquake is a grim reminder of the potential for another strong-motion mega-earthquake along the Pacific Northwest coast, geophysicist John Anderson of the University of Nevada, Reno told members of the American Association for the Advancement of Science in a lecture at their annual conference in Vancouver, B.C. Sunday.

“The Cascadia fault line, which runs from southern Canada all the way to Northern California, could have much stronger ground-motions than those observed in Japan,” Anderson, a professor of geophysics, said. “The Tohoku earthquake, while only half the length of Cascadia, is an analog for an earthquake that could happen here in the northwestern United States and southwestern British Columbia.”

Both Japan and Cascadia sit above subduction zones that dip at a low angle beneath the land. One might consider them roughly mirror images, he said.
“In this mirror image, one can see that if the same earthquake occurred in Cascadia, the fault would rupture to a significant distance inland, since the Cascadia trench sits much closer to the coastline than the trench off the coast of Japan, Anderson said. “Some models predict that a Cascadia earthquake will not rupture so far under the land, but if it does, the data from the Tohoku earthquake predict stronger ground motions along our west coast than those seen in Japan. In any case, the ground motions from Tohoku are critical for understanding the seismic hazard here in Vancouver, and in Seattle, and Portland, and Eureka and all points in between.”

In Cascadia, the last great earthquake occurred on January 26, 1700. Based on the size of the tsunami, the magnitude of that earthquake was about magnitude 9.0.

“Although the average interval is apparently larger, earthquakes of this size in the past may have recurred with intervals of as small as about 300 years. So it would not be a scientific surprise if such an event were to occur in the near future,” Anderson said. “If you live in the Pacific northwest, look at the videos of Tohoku as a reminder to be prepared for an earthquake and tsunami.”
