Please watch this video clip all the way through. It will take 

about the same length of time that the shaking was 

experienced in the 1964 Alaskan earthquake. This M9.2 

megathrust earthquake lasting four minutes and thirty-eight 

seconds. This magnitude 9.2 megathrust earthquake is also 

known as the Great Alaskan earthquake and Good Friday

earthquake

Reference: 1964 Alaska earthquake - Wikipedia

In October, 1966, I (the author, Stan G. Webb) first moved to work as the Cost Accountant for the Northern Vancouver Island, Port Hardy Division of McMillan Bloedel Ltd. (MB), crews were still yarding (pulling) logs off the Hardy Bay (Quatse River) mudflats.  They had been pickup from the MB Port Hardy Division log dumping grounds by the Tsunami caused by the 1964 Alaskan Earthquake, and had been deposited 50 to 750 metres upstream, on those Hardy Bay (Quatse River) mudflats.

Most of you know that I am an author, photojournalist and educator. My first book was published in New York in 1982 and I have had hundreds of other professional articles published, as well.

You know that I delve into dark and deep places like the Cascadia Megaquake© which is past due and expected any day now, and Respiratory Illness© which I presently have. These things can all get quite depressing and I want you to know that I do keep them in balance with all of the beauty and light that is around us, always. So I also Breath Colour, Eat Colour, Feel Colour, Live Colour, See Colour, Smell Colour on my artistic photography website Stan G.Webb - In Retirement ©. I've even won some awards ie: Over Lynn Valley

Four of my other favorites are:

It was getting dark and I was hoping to catch some of the night pollinators: ants, bats, moths etc. and I did not want bright light to scare them away.

Dr. Chris Goldfinger of Oregon State University, explains the science and the practical  realities of the impending earthquake. He's joined by Rob Johnson, FEMA Disaster Recovery Reservist who will help us understand how our community should respond to such a disaster.

USGS publishes a new blueprint that can help make subduction zone areas more resilient

The USGS has just published a new blueprint for advancing science and
resilience related to subduction zone hazards, entitled Reducing Risk
Where Tectonic Plates Collide – A Plan to Advance Subduction Zone
Science. This new Plan describes how the USGS may leverage scientific
and technologic developments, address its stakeholder needs, and
maximize capabilities through partnerships – with the overall goal
of reducing the risks posed by subduction zone events. The Plan is
featured on the USGS main webpage, and a quick summary of the Plan is
provided in an accompanying Fact Sheet (written for a general
audience).

Earthquakes, Tsunamis and Volcanoes: History and Stories of Survival, both Fiction and Non-Fiction

This is all very serious … a great Icelandic artist, Björk Guðmundsdóttir, has done a very visual representation (shown earlier in the blog/website): 
[https://cascadiamegaquake.blogspot.ca/2017/05/bjrk-mutual-core-official-art-music.html]

Selected Bibliography, UPDATED TO:  May 25, 2017, and
Hyperlinked to the North Shore of Vancouver, BC's main libraries:

  • Article from The New Yorker - “When the Cascadia fault line ruptures, it could be our worst natural disaster in recorded history” ... READ ITIf, on that occasion, only the southern part of the Cascadia subduction zone gives way ... the magnitude of the resulting quake will be somewhere between 8.0 and 8.6. Thats the BIG ONE. If the entire zone gives way at once, an event that seismologists call a full-margin rupture, the magnitude will be somewhere between 8.7 and 9.2. That’s the VERY BIG ONE. Kenneth Murphy, when he was interviewed for the article, and who had directed FEMA’s (Federal Emergency Management Agency: FEMA.gov www.fema.gov/) - (Disaster mitigation, preparedness, response, recovery, education, and references.) Region X, the division responsible for Oregon, Washington, Idaho, and Alaska), says, “Our operating assumption is that everything west of Interstate 5 will be toast.” (The Editor of this note – SGW) adds that, in the CSZ - Cascadia Subduction Zone, the Juan de Fuca Plate continues all the way up to the Nootka Fault, midway up Vancouver Island's West Coast. There is another tectonic plate to the north, the Explorer Plate as well as the south, the Gorda Plate. The problem, you see, is that the land under our feet is NOT really “as firm as the ground we walk on”.
  • It is the North American Plate covering most of North America, Greenland, Bering Sea, Atlantic Ocean, Arctic Ocean. It starts in the east, at the Mid-Atlantic Ridge, and covers the area westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. It is moving inexorably to the west at between a speed of variously reported as 56–102 mm (2.2–4.0 in)/year, sometimes between 15-25 mm (0.59-0.98 in)/year, relative to the African Plate.  Recent GPS readings on the tops of the Olympic Mountains in Northwest Washington through to the Coast Range North West of Campbell River show that these mountains continue to be forced up, and over the Pacific Plate which is subducting beneath. The Pacific Plate  is 75,900,000 km2 (29,300,000 sq mi).  The CSZ - Cascadia Subduction Zone, the boundary between the North American Plate and the Pacific Plate, has been locked up for over 300 years.  If it breaks loose all at the same time, in a full margin rupture, at present the net deficit for the entire Pacific Northwest and Southwest B.C. is about down two meters (6.5 feet) and a jump 6.5 meters (21 feet) to the south-west.  In other words, the entire west coast will drop down two meters (6.5 feet) and lurch 6.5 meters (21 feet) to the south-west.  In each of many other Subduction Zone events in Alaska, Chile, Indonesia, Japan, Portugal these are all accompanied by megatsunamis.  The type of subduction zone great quake happens continuously over a period lasting for six (6) to fifteen (15) minutes.
  • Of special note: Cascadia's Fault The Deathly Earthquake That Will Devastate North America By Thompson, Jerry Book - 2011
  • The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million square kilometres (40,000,000 sq mi), it is the largest tectonic plate.
