Physicist Dr. Michio Kaku discusses the Cascadia Subduction Zone.
A couple of key paragraphs:

Kaku said the Cascadia zone is more dangerous because it can muster 30 times the energy than the infamous San Andreas fault. Furthermore, according to seismologists, certain plate activity will lead to a much more catastrophic effects.

CBS News: According to the FEMA director responsible for Oregon, Washington, Idaho and Alaska, the operating assumption is that "everything west of Interstate 5 will be toast."

Global Moderator Ruth sent me this email and video. Posting the video first: Heads Up 20- 30 Days Until Large Earthquake? Straight of Juan de Fuca Slowing Moving Quakes
link: https://youtu.be/UaG1JUC0hLY
...
from Ruth: I’m VERY concerned about what is going on in the Cascadia area off Washington, Oregon, and N. California.
Mary Greely is keeping track of this.

Basically:
1. swarms of small earthquakes have been occurring for awhile now. The location of the swarms is slowly moving south along the fault line.
2. there is a location she points to on her map discussing this which seems to have been the trigger location, in the past, for big earthquakes to set off.
3. she is suggesting that the experts she uses speculate the moving swarms will eventually set off that trigger location for the “big one”.
4. the movement of the swarms to get to that point would happen in the next 20 to 30 days.
5. keeping in mind the stunning article about a month ago that was featured on Fox News from a newspaper article about the Big One hitting and everything west of the main highway would become toast - we may be on the verge of something earth shaking, pun intended.
6. Mary discusses in one of her videos the connection between those fault lines and the ones in California and a branch going off to Yellowstone.

This is looking like a staging of dominoes.

There was also a video I saw that discusses Russia’s discoveries about Yellowstone. Not long ago there were Russian aircraft flying along the west coast. They were in fact studying the magnetic anomaly coming up in this region because it was messing with their advanced aircraft.

I’m just wondering if Jim Farmer or Linda may have posted anything on this, connecting the dots. Mary Greely is awesome. I think I emailed you some links to the above videos.

https://en.wikipedia.org/wiki/1700_Cascadia_earthquake

1700 Cascadia earthquake

From Wikipedia, the free encyclopedia

The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26 with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate that underlies the Pacific Ocean, from mid-Vancouver Island in British Columbia, Canada, south along the Pacific Northwest coast as far as northern California. The length of the fault rupture was about 1,000 kilometers (620 miles) with an average slip of 20 meters (66 ft).

The earthquake caused a tsunami that struck the coast of Japan,[3] and may also be linked to the Bonneville Slide and the Tseax Cone eruption in British Columbia.

Evidence

Evidence supporting the occurrence of the 1700 earthquake has been gathered into the 2005 book The Orphan Tsunami of 1700, by Brian Atwater, Kenji Satake, David Yamaguchi, and others.

The evidence suggests that it took place at about 21:00 on January 26, 1700 (NS). Although there were no written records in the region at the time, the earthquake's precise time is nevertheless known from Japanese records of a tsunami that has not been tied to any other Pacific Rim earthquake. The Japanese records exist primarily in the prefecture of Iwate, in communities such as Tsugaruishi, Kuwagasaki and Ōtsuchi.

Scientific research

The most important clue linking the tsunami in Japan and the earthquake in the Pacific Northwest comes from studies of tree rings (dendrochronology), which show that several "ghost forests" of red cedar trees in Oregon and Washington, killed by lowering of coastal forests into the tidal zone by the earthquake, have outermost growth rings that formed in 1699, the last growing season before the tsunami. This includes both inland stands of trees, such as one on the Copalis River in Washington, and pockets of tree stumps that are now under the ocean surface and become exposed only at low tide.

Sediment layers in these locations also demonstrate a pattern consistent with seismic and tsunami events occurring around this time.[8] Core samples from the ocean floor, as well as debris samples from some earthquake-induced landslides in the Pacific Northwest, also support the timing of the event,[7] and archaeological research in the region has uncovered evidence of several coastal villages having been flooded and abandoned around 1700.

Cultural research[edit]

Local Native American and First Nations groups residing in Cascadia did not have a written tradition of record-keeping, so the event is not as well-documented locally as the Japanese tsunami is. However, numerous oral traditions describing a great earthquake and tsunami-like flooding do exist among indigenous coastal peoples all the way from British Columbia to Northern California.[6][10] These do not specify an exact date, and not all earthquake stories in the region can be definitively isolated as referring to the 1700 quake in particular; however, virtually all of the native peoples in the region have at least one traditional story of an event much stronger and more destructive than any other that their community had ever experienced.

Some of the stories do contain temporal clues — such as an estimate of how many generations had passed since the event — which can be traced back to a date range in the late 1600s or early 1700s, or which concur with the event's timing in other ways. The Huu-ay-aht legend of a large earthquake and ocean wave devastating their settlements at Pachina Bay, for instance, speaks of the event occurring on a winter evening shortly after the village's residents had gone to sleep. Masit was the only community on Pachina Bay not to have been wiped out, as it sat on a mountainside approximately 75 feet above sea level.[12] Nobody else from Pachina Bay survived the event — Anacla aq sop, a young woman who happened to be staying at Kiix?in on the more tsunami-sheltered Barkley Sound at the time of the event, came to be known as the last living member of her community.

Kwakwaka'wakw (Kwakiutl) stories from the north end of Vancouver Island report a nighttime earthquake which caused virtually all houses in their community to collapse; Cowichan stories from Vancouver Island's inner coast speak of a nighttime earthquake, causing a landslide that buried an entire village. Makah stories from Washington speak of a great nighttime earthquake, of which the only survivors were those who fled inland before the tsunami hit. The Quileute people in Washington have a story about a flood so powerful that villagers in their canoes were swept inland all the way to the Hood Canal.

Ethnographic research has focused on a common regional pattern of art and mythology depicting a great battle between a thunderbird and a whale, as well as cultural signifiers such as earthquake-inspired ritual masks and dances

...
http://dutchsinse.com/

...Clearly things are on the move below the Pacific plate.  The deep earthquakes over the past several days are another sign of the new unrest event spreading out across the whole region.

The activity around the Pacific plate has been building over the past several days.

Over the past week, multiple deep M4.0+ earthquakes built into several M5.0+ earthquakes (up to March 18).  As the earthquakes grew in magnitude, they spread out across the region – giving away the fact that a new unrest event was (is) brewing in certain regions of the West + North Pacific.

Earthquake Early Warning - (EEW)

Earthquake early warning (EEW) detects and measures earthquakes fast enough that warning can be given before the strongest shaking arrives, providing seconds to minutes to prepare.

Earthquake early warning is being implemented in many locations around the world.  The 2011 Tohuku Earthquake demonstrated some of its advantages.  The earthquake was recognized as serious within 30 seconds of its initiation offshore.  Tokyo residents had ~30 seconds warning of approaching strong ground motion.  Cell phone alarms warned millions of people when large aftershocks were likely to soon rattle them.

On the west coast of the the US, with USGS funding, Cal Tech and UC Berkeley have developed and are testing an early prototype EEW system known as ShakeAlert in California.  In November, 2012, the Moore Foundation announced awarded grants to Cal Tech, UC Berkeley, and the University of Washington to develop and begin testing this prototype system.  The USGS will help coordinate these activities.

NEWS: EEW in the News

PNSN announces launch of integrated West Coast Earthquake Early Warning System

April 14, 2017

by Shelley Chestler

On Monday morning (April 10) the Pacific Northwest Seismic Network (PNSN) was buzzing with activity, but not seismic activity. Network employees were sporting PNSN t-shirts and there were numerous outside officials wearing splashes of University of Washington purple. Reporters from The Seattle Times, KIRO News, the UW Office of News and Information, and more where crowded into the small lab room, surrounded by recording equipment. The lab room itself, with its old school, drum seismograms, was accessorized with extra monitors, a podium, and a clean, purple tablecloth covering the long table, normally cluttered with various earthquake demonstrations.

What was the occasion? The Seismic Network hosted a press conference to announce the rollout of a new version of the earthquake early warning (EEW) system, ShakeAlert, which is now fully integrated across the entire West Coast of the United States. Speakers included the Dean of the UW College of the Environment, Lisa Graumlich, Dave Applegate and Doug Given from the United States Geological Survey, U.S. Representative Derek Kilmer, Washington State Seismologist, John Vidale, Maximilian Dixon from the Washington State Emergency Management Division, and Dan Ervin, chair of RH2 Engineering.

https://pnsn.org/pnsn-data-products/earthquake-early-warning

EEW, PNSN announces launch of integrated West Coast Earthquake Early Warning System
April 14, 2017

[Article continues]
Previously the EEW system in the Pacific Northwest was detecting earthquakes and issuing warnings to a beta test group, but the warnings were not being utilized. Now, while the system is not yet ready to send alerts to the public, warnings issued to pilot users will be used to test earthquake response systems. Users include RH2 Engineering in Bothell, WA, which will use the alerts to secure municipal water and sewer systems, and the Eugene Water and Electricity Board in Oregon, where alerts will be used to lower canal water levels above a residential area and turn off turbines at a power plant.

While the release of the updated system marks a large step forward for West Coast earthquake early warning, there is still more work to be done to allow the system to reach its full potential. Both Applegate and Given emphasized that the system only has about half the funding needed in terms of annual support. The development of the system has so far been funded by a combination of public and private grants, including support from the Gordon and Betty Moore Foundation, Amazon Catalyst, and Puget Sound Energy.

“Federal investment in science matters,” said representative Derek Kilmer.

Kilmer believes that Monday’s press conference highlights the value of the EEW system. He hopes that Congress will realize the benefits of having an EEW system across the West Coast and respond. Additional funding will go towards installing new earthquake-recording stations, improving telecommunications between stations and network computers, continued testing of the system, and hiring new staff.

Currently, the system only includes 700 of the 1700 stations needed to cover all the hazards and populations on the West Coast. While the EEW system can move forward with the existing stations, earthquakes in some places, for example parts of Eastern Washington, will be detected less quickly than with the full station set or not at all. Unfortunately, installing new stations is not like “planting flowers” reported Given. Not only do new stations cost money, getting permits to put stations on private, state, and federally owned land is time consuming.

Another critical component needed to expand the system to be able to issue public alerts is education. Receiving a warning on your cellphone is not useful unless you know what the alert means and how to respond. While there is no funding for education yet, reported Dixon, the ultimate goal of EEW education is for the public to be able to react to warnings with a practiced, automatic response.

Despite the fact that a fully-fledged West Coast EEW system still requires more time, work, and funding, all the press conference speakers emphasized the utility of having earthquake warnings.

“(The earthquake risk on the West Coast) cannot be overstated,” stressed Given.

The EEW system will save lives, preserve infrastructure, and mitigate the loss of productivity post-quake. The release of the West Coast integrated system marks a milestone in earthquake preparedness.

Experts 'Concerned' Because Long Valley Caldera Volcano Is 'Moving' - High Number Of Earthquakes 'Indicators Of Pending Volcanic Eruption'!

http://allnewspipeline.com/Is_It_Going_To_Blow.php


Long Valley Caldera near Mammoth Lakes has experts "concerned" because over the last 100 days the volcano has been "acting up" as NewsPrepper describes it and the unusual amount of Earthquakes that have hit Mammoth lake over the last month means all eyes should be carefully watching these earthquakes and especially this particular volcano.

    In 1915, Lassen Peak erupted and wrecked a huge portion of the state. Over the last 100 days, the much larger Long Valley Caldera has begun acting-up. And what it’s doing has Geologists at the US Geological Survey “concerned.” The Caldera – the mouth of the Volcano – is . . . . moving.

    According to scientific instruments monitored by the United States Geological Survey (USGS) the area in vicinity of the Long Valley caldera is deforming and moving rapidly compared to previous records. How sure are they? “95% (confidence interval), the (data) ensemble is significant”

    The data is showing on a recent timespan that the amount of movement is causing STATISTICALLY SIGNIFICANT STRAIN in the rock in the area. This is not conspiracy-theorist conjecture or amateur geology antics, this is from the USGS itself.


According to a March report found at AOL science and tech news, this massive super volcano "has the potential to unleash a fiery hell across the planet, and the magma-filled mountain has a history of doing so." While the article downplayed the likelihood of an imminent eruption, the article was written before the 1,000+ EQ that are being reported on now.


WOW-NEVER BEEN LIKE THIS BEFORE--1249-EQS IN THE MAMMOTH LAKES REGION OF CALIFORNIA- NEVADA BORDER AREA, OVER LAST WEEK -THESE ARE TURNING INTO VERY DANGEROUS INDICATORS OF PENDING VOLCANIC ERUPTION

“Something’s Not Right in Southern Oregon”
“Are we about to experience a severe natural disaster?”

https://www.earthfiles.com/2018/03/19/somethings-not-right-in-southern-oregon/

March 19, 2018 Rogue Valley, Oregon – Earthfiles has been receiving worried emails from viewers and listeners who sense that something is significantly wrong in a number of American communities — ranging from absence of insects and pollinators to missing birds. This morning I received the following email from a man who has lived in southwestern Oregon’s Rogue Valley eleven miles north of Medford for 30 years. What he describes in his email are such striking changes around him that he now wonders if a large seismic event is about to happen and the birds at least know in advance.

“I live on twenty acres on the tip of a mountain that overlooks the entire Rogue Valley. I live among a vast array of wildlife, and I pay particular attention to the avian population.

Normally, the Vultures arrive back in the Rogue Valley around the first week in March, but this year the Vultures started returning the first week in February in small numbers, but it was still significant because I’d never seen that before in the nearly 30 years I’ve lived here.

My hummingbirds are legion and I feed them with up to four large feeders. The Anna Hummingbirds stay all through the winter, while their smaller brethren return from the south arrive about the same time as the Vultures. Not only have the smaller Hummingbirds not returned yet, but all of a sudden, my huge population of Anna Hummingbirds have vanished completely and I haven’t had to fill a single feeder in at least a full week.

But what has really got my attention is the fact the Swallows have not yet returned, and that, more than any other barometer, tells me something is very, very wrong. The Swallows always return the first week of March too, but this is March 18th, and they are nowhere to be seen.

But my house at 9.0 magnitude quake? Forget it! A 9.0 lasting a minute or more will collapse just about every structure currently standing in Southern Oregon.

So I am preparing for the worst and hoping I’m just wrong. But something’s just not right in Southern Oregon, and I’m not taking any chances.”

Max, that is amazing testimony from an Oregon resident, and much more riveting that anything on CNN or Fox where they blather on about "the chances of a quake are..." etc. 

As they say, no wildlife was lost in the Indonesian tsunami, cuz they sensed it long before and left the area, and am betting that guy's beloved hummers and other wildlife are hiding out somewhere right now.

We wish him and his wildlife well!

Per this a.m.'s edition of Marfoogle News, based in Seattle, the utility company owning those poles has issued a bizarre cover story as to why 26 poles fell all at once:

...because lightning supposedly struck one and they all went down like dominoes...

However, testimony from locals, as well as video footage, revealed no unusual weather in the area, but heavy shaking of the cameras, as in possible unreported seismic activity at the time?

Marfoogle News posted a report a few hours ago that numerous buoys off of the Northwest coast of the U.S. are reporting a 4-foot drop in ocean water level, suggesting that a major plate shift has occurred.  This means the Juan de Fuca plate has abruptly slipped beneath the North American Plate, and a large quake may follow.

In 1700, a similar event occurred which resulted in an estimated magnitude 9 quake and a tsunami that washed 10 miles inland.

Did the ocean water level go down, or did the sea floor go up at that location?

The buoys do not record water level, they record water depth.

(The video is too long for me to watch)

If the sea floor went up, then the tectonic plate at that location is being raised.  Either it is being pushed over the adjoining plate, or the adjoining plate is being pushed under it, or both.

That would be consistent with the prediction by zetatalk that the Pacific Ocean will contract in width as the tectonic plates overlap with the west-side edges of the tectonic plates subducting and east-side edges rising.

A caller on this morning's Marfoogle News program who is a professional GIS surveyor reported some disturbing news:

He is working on a project to mark historic graves by GIS within the Cascadia region.  The project was supposed to have taken a methodic 5 years to complete, but staff are now being pushed hard to complete it ASAP, working longer hours daily with no time off until it's done.  The word is that the federal government knows a large tectonic plate slip is imminent, and that everything west of I-5 is expected to shift 45'.

Adam of Marfoogle News reported yesterday that folks in the Seattle area experienced the ground suddenly dropping beneath them during the middle of the night. 

It happened to him in his home while he was on the phone.

Quote
I was talking to all my mods, and then all of the sudden, what they hear me say is "Get the baby - Let's go!

A local gas station attendant felt the same thing.  An adjacent casino operator said that when the ground fell, it was a very vertical fall, as the chips on the casino tables never moved.  Another local was leaning on a bar table, and fell over it when the ground dropped.

The reported quake was only a 4.7 magnitude (downgraded by USGS to a 4.4), but the nature of the sudden jolt distinguished it from previous quakes.  He says that scientists are reporting ground liquifaction in the area (sources?).

Adam and his family have kept their but-out bags by the door for months now, and he and his wife managed to grab the children, pets and bags in 45 seconds and exit safely in the car to a prearranged safe location, due to much practice.  On an earlier premonition, he had moved the car out from beneath a carport, to prevent it from collapsing on them during an escape.

He is visibly rattled in this short video, which was a re-take from the previous version in which he was substantially more rattled.

Now is the time to get supplies, he warns, for those in Cascadia.  Those in the area who experienced the ground dropping should call relatives who might have been asleep at the time and let them know what just happened.

He also mentioned that Dutchsinse had noted that the USGS's live feed had been cut off, and that Youtube was blocking live video telecasts.

GREAT article:

How the Coming Cascadia Subduction Zone Event Will Produce An Extinction Level Event (Part One)  ???

https://thecommonsenseshow.com/activism-agenda-21-conspiracy/how-coming-cascadia-subduction-zone-event-will-produce-extinction-level-event-part-one

Since attending the True Legends conference in Branson, MO., in September, I have often reflected on Steve Quayle's presentation. Seemingly out of nowhere, I began to wonder if the quake would impact the nuclear power plants on the coast in Californial. The answer is yes, when I asked the question to a confidential informant (CI). I have learned that the CIA is flying U-2 spy planes up and down the coastline on a 24/7 basis. The threat is the encroaching magma as well as the two plates interacting off of the coast. Subsequently, I began to research the question of nuclear power plants being impacted by this activity. Here is what I found. Walk with me through the progression of data which led me to unmistakable conclusion, that we are looking at an extinction level event.

The death toll of a Cascadia Subduction Zone event would kill nearly everyone west of Interstate 5. However, when we mix in nuclear power plants in California, it becomes clear that this event will threaten everyone on the face of the earth. 

This article is the first of two parts. Part One will establish the threat. Part Two will attempt to establish the scope of the threat.

The U.S. Geological Survey (USGS) seismic hazard map show the probability level for an earthquake across the U.S. based on ground shaking, faults, seismicity and geodesy. This information helps dictate everything from building codes, insurance rates and public policy. It is for this reason that the warnings are not forth. The pre-event economic devastation would be incalculable and therefore will remain unreported until the even occurs. Some place the risk at 1 in 10 to occur in the next 50 years. Other estimates place the risk at 30%.

U.S. Seismic Activity Near Nuclear Power Plants

Looking at the overlap of U.S. nuclear reactors (both power and research facilities) and earthquake zones is alarming and  shocking. The accompanying map clearly illustrates the threat.

"The Cascadian Subduction Zone" off the coast of British Columbia, Washington, Oregon and the northernmost part of California shook with a vigorous 9.0 on January 26, 1700. It produced a huge tsunami that its geological-mark on Humboldt County. It even reached Japan! But tsunamis from earthquakes around South America and the Aleutian-Alaskan region have posed a greater threat to the West Coast than locally generated tsunamis." Subsequently, history gives us a partial blueprint of what lies ahead. However, in 1700, there weas no electrical grid or nuclear power plants.


My source informed me that as per NERC policy, nuclear power plants are required to have enough diesel fuel to run for a period of seven days. Some plants have thirty days of diesel. This is the good news, but it is all downhill from here.

The Unresolved Power Blackout Problem

Now that the danger is exposed, let's ask the earthquake question. When the Canadian Subduction Zone goes critical, this will cause a loss of power. Will the power be restored in 7-30 days, which is the time that all nuclear power plants are designed to be offline and still meet the cooling of the fuel rods question? The answer is frightening. If power is not restored, and that is assuming the structure of the plant is still intact following the earthquake, the authorities would have 1-4 weeks to restore power, at most.

In conclusion, we must face the possibility that when we mix in nuclear power plants with the Cascadian Subduction Zone event, we are facing an extinction level event
