and Yahoo are NOT to be used in any way. I've experienced ID theft,
personal information stolen and used. In November, 2016 I fired Marisa Meyer and Yahoo after she leaked information on 500 million of us users. Facebook and Google are now also under scrutiny. People are too loose with their private information. GPS on my cellphone or camera, I don't think so.
For the next
two months I'll be head down, concentrating on this. My deadline, I
hope, is 9:00PM PST, Saturday, January 26, 2019, the 319h
anniversary of the last Cascadia Megaquake which struck the west
coast of North America at 9:00PM on Tuesday, January 26, 1700 (21:00)
local Pacific Standard Time. If we can help save one life, it'll be
worth it.
I would like this to be kept quiet until we have finished polished written
material and have presentations ready. I will be laser focused on
preparing material to help educate people ~ so that they can help
prepare their grandchildren for this.
At 9:00PM PST,
Saturday, January 26, 2019. I hope by then, that we will all be on
the same page, and all have the chance to go out and discuss this.

I highly recommend that visit. Gimli is on Central Time, two hours
earlier than Pacific Standard Time. I met
with some of the descendants of families of the seismic survivors who
fled an eruption of the Icelandic
volcano
Askja
in 1875 (1/3
of the entire population of Iceland). Icelandic

are Canadian

has the largest ethnic Icelandic population outside Iceland,

Some details: The last Cascadia Megaquake struck the west coast of
North America at 9:00PM on Tuesday, January 26, 1700 (21:00) local
Pacific Standard Time. The next day the Megatsunami arrived in Japan at midnight,
Wednesday Japan Standard Time (JST). (5:00AM next day, Coordinated Universal Time (UTC) The Cascadia Megatsunami 'wave
train' was in a series of seven long-period waves, 20 – 30 minutes
apart, later. A long-period wave is one where the crest of each
successive wave can be 300 ~ 800 kilometres, and more, apart. Often
the third in the series is the largest and most destructive. These
types of 'waves' are not really what I would call a waves, at all; a
'flood' would be more descriptive.
Geologists
have determined the US Pacific Northwest is not prepared for such a
colossal quake. Canada is worse. Those geologists estimate the tsunami
produced
could
reach
heights of 24 to 30 m (80 to 100 feet). A 2004 study revealed the
potential for relative mean sea level rise (caused by subsidence)
along the Cascadia
subduction
zone. My 'reverse engineering' and physics show it higher. At Anacla
the
tsunami would have been twelve stories, over 37 metres (120 feet)
high.''.
All along our west coast First Nations have stories and talk about
it, referring to it as a flood. Floods come in low, and raise from
below. In a Cascadia Megaquake the source of the Cascadia
Megatsunami is
referred
to as the Cascadia
fault, the point at which the Explorer, Juan de Fuca and Gorda Tectonic Plates start 'subducting' (or sinking) beneath the overriding North American Tectonic Plate. That starts happening about 80 kilometres off the coast, down 2,000 metres or so below the
surface of the Pacific Ocean. When the Cascadia Fault ruptures it
will push up an entire column of water from the torn ocean bottom to
the top of the ocean surface, from north of Vancouver Island, all
along 1.000-1,200 kilometres south to northern California. In Japan,
8,000 kilometres away, traveling at the speed of a Boeing 747 Jumbo
Jet (700 kilometre/hour), the last Cascadia Megatsunami arrived,
after having crossed the International Date Line, through seven time
zones at around midnight, January 27, 1700.

on January
26, 2016 it
was the 316th (in 2016) anniversary of the 1700 Cascadia megathrust
earthquake and tsunami!
“It
invaded towns along the coast, inexorable. The worst damage happened
in the north. In the Miyako Bay area, where the tsunami probably
reached a height of five meters, the floodwaters ripped apart or
washed out thirteen houses in the town of Kuwagasaki as villagers
fled to high ground. Twenty-one more houses burned in the ensuing
fires.* Happily, everybody lived, and they would be able to rebuild
when the fires were out and the waters receded. (In other areas it was reported to be four stories, 12 metres).
Seven
kilometers away in Tsugaruishi, houses along the shore were swept
away. Floodwaters proceeded into town a kilometer inland from the
bay, and the tsunami barreled up the Tsugaruishi River all the way to
Kubota Crossing. Villagers panicked when it nearly reached
Inarinoshita, just below Inari Shrine. But they and their shrine
survived the night. … (more

The
Last Cascadia Great Earthquake and Tsunami;
313 Years and Ticking
Thousands
of coastal residents settled in for the night on January 26th 1700
when the ground began to shake. For most, the first signs were
subtle, dogs barked nervously as the primary or “P” wave
vibrations passed by. The earthquake became unmistakable when the “S”
(secondary or shear) waves arrived at village after village traveling
at about 6 kilometers a second as the entire Cascadia Subduction Zone
ruptured. The 1000 km long fault rupture propagated from its origin
at about 3 km a second, generating fresh seismic waves as the fault
continued to unzip and slip. Assuming the rupture began in Northern
California, it likely took over 5 minutes break the entire fault to
northern Vancouver Island.
The
earthquake that released about 1500 times the seismic energy than the
2001 M 6.8 Nisqually Earthquake, and can be seen as a connected
series of large earthquakes at least one of which produced very low
frequency waves with 10s of meters of displacement, and a dramatic
popping up of the sea floor that lifted a great column of water;
The
Last Cascadia Great Earthquake and Tsunami; 313 Years and Ticking
That
uplifted column of water then collapsed producing a series
of tsunami waves
that would batter the
coastline through the night and cross the Pacific basin. Though all
people west of the Cascades were disrupted by the shaking and some
injured by falling logs and possessions, it was the water that likely
claimed the hundreds of lives lost that night when villages were
overtopped by tsunami generated floods.
The
1980s was a decade of discovery of evidence for great earthquakes in
the Cascadia Region. Tom Heaton and Hiroo Kanamori published a paper
asserting the Cascadia Subduction Zone was indeed actively deforming
and is likely to produce great earthquakes. Brian Atwater’s 1987
paper in Science provided the necessary “ground truthing” of
these theories describing repeated abrupt co-seismic land level
changes along our coast and evidence of tsunami inundation following
periodic great earthquakes. Atwater with many scientific colleagues
continued to work over decades to tease out the details of magnitude,
shaking levels, tsunami hazards, and reoccurrence rate of great
Cascadia earthquakes. This work also involved the study of
earthquakes in other subduction zones around the world and provided
the precise date and even the hour of the 1700 earthquake derived
from the arrival time of the Cascadia Tsunami in Japan. We now know a
~magnitude 9 earthquake struck our region on January 26, 1700 at
~9:00 PM. We also know the fault is reloaded with strain and capable
of producing another great earthquake today though it is probable
that we have many decades with which to prepare for this inevitable
earthquake.
Scientists
have had many examples of these subduction zone earthquakes to study
over the past 10 years as hundreds of thousands of people have died
in great earthquakes and the tsunami waves they produced. The largest
of these, the Mw 9.1 2004 Sumatra-Andaman Earthquake and Indian Ocean
Tsunami killed between 230 and 300 thousand people in Indonesia and
at least 15 other nations. A dozen other great earthquakes occurred
over the past 10 years including the 2010 M 8.8 Maule, Chile
Earthquake and the Great East Japan Earthquake of March 11, 2011 in
which over 15,000 Japanese died, over 92% from drowning during the
tsunami flooding.
The
Cascadia Subduction Zone has remained locked, loaded, and quiet
through all this tumult. It does not even produce the small
earthquakes so prevalent in other subduction zones around the world.
The Cascadia Subduction Zone behaves differently than all other
subduction zones on the planet. Scientists also see significant
variation in behavior from one subduction zone to the next so it is
hard to know what lessons should we learn from these earthquakes to
lower our losses when our fault breaks loose again. Despite the
natural variations between faults and earthquake effects, some clear
conclusions can be made.
Emergency
response will be slow and households, particularly in rural and
coastal areas, need to be self sufficient for food, water, and
medicine for weeks, not just days. It is not realistic to think that
the millions of people impacted by this regional event will receive
assistance within 72 hours of the earthquake. Unfortunately, only a
minority of households have the old 3 day minimum of disaster
supplies on hand. We must set aside more.
