The Next BIG Earthquake
At Risk: The GREAT Earthquake Threat Facing Southern British Columbia and the Pacific Northwest
February 04, 2007
Sherwood Ensey

It has been 307 years since a GREAT earthquake struck the Cascades region of the Pacific Northwest and southern British Columbia. The last known GREAT earthquake that struck the Cascades region is thought to have taken place on January 26, 1700, and been 9+ in magnitude.

"The earthquake shaking collapsed houses of the Cowichan people on Vancouver Island and caused numerous landslides. The shaking was so violent that people could not stand and so prolonged that it made them sick. On the west coast of Vancouver Island, the tsunami completely destroyed the winter village of the Pachena Bay people with no survivors. These events are recorded in the oral traditions of the First Nations people on Vancouver Island. The tsunami swept across the Pacific also causing destruction along the Pacific coast of Japan. It is the accurate descriptions of the tsunami and the accurate time keeping by the Japanese that allows us to confidently know the size and exact time of this great earthquake.

The earthquake also left unmistakable signatures in the geological record as the outer coastal regions subsided and drowned coastal marshlands and forests that were subsequently covered with younger sediments. The recognition of definitive signatures in the geological record tells us the January 26, 1700 event was not a unique event, but has repeated many times at irregular intervals of hundreds of years. Geological evidence indicates that 13 great earthquakes have occurred in the last 6000 years."

Damage and death toll estimates from the earthquake and the resulting tsunami of 1700 differ. Estimates of the height of the tsunami generated by the earthquake, which struck Japan some 10 to 20 hours after the earthquake, ranges from 3 to 6 meters in height.

An animation, prepared by Kenji Satake of the 1700 tsunami is located here:

Future large scale ruptures of the offshore faults in the Cascadia region, resulting in GREAT earthquakes, will generate tsunamis that will follow the same approximate path as the ones shown in the above animation. The resulting damage and death toll from future tsunamis will rival, or exceed the one that struck the Indonesian-Asian region on December 26, 2004.

Oral tradition in Japan, which appears to be backed by quite a bit of geologic proof, indicates a great tsunami struck the ancient city of Kamakura, Japan (about an hour from Tokyo) in 1498. The only thing left standing in Kamakura after the tsunami was a huge Buddha stature, 13.35 meters in height, which is still there. The temple that surrounded the Buddha statue was washed away by the tsunami. The elevation of the Kotokuin Temple site where the Buddha statue sits, ranges from 90 to 151 feet above sea level. Given that information, the size of the 1498 tsunami that destroyed Kamakura, must have been enormous, killing ten's of thousands. One troubling question mark about the origins of the earthquake that caused the tsunami remain: Where exactly was it located? Could it have been the Cascadia region of North America?

The Juan de Fuca plate is a very active and unstable plate, capable of producing the same type of rupturing and earthquake activity, as the GREAT Indonesian earthquake of December 26, 2004.

"Cascadia is America's own tectonic version of Sumatra, where the magnitude 9.3 earthquake and tsunami of 2004 occurred. Stretching off the Pacific shore from northern California some 1300 kilometers to the tip of Vancouver Island, the Cascadia subduction zone appears capable of its own magnitude 9 earthquake. What do we know about its behavior and its history? What would that great Cascadia earthquake be like?"

There is a possibility that one of the future GREAT earthquake's the world will see, in the near future, will come from the Cascadia region of North America, and that it will originate with the Juan de Fuca plate.

Since 2005 there has been a series of ongoing "creeping" earthquakes taking place within the subduction zone of the Juan de Fuca plate.

Two weeks prior to February 2, 2007, scientists in Canada began picking up "...an unusual travelling tremor deep inside the earth’s crust."

"Herb Dragert, a researcher with the Geological Survey of Canada in Victoria, said the wandering tremor is the result of subtle, slow slippage of the Juan de Fuca plate as it pushes against the North American plate in an area known as the Cascadia subduction zone.

A sudden slippage of the two plates would trigger an earthquake similar in magnitude to the one off the coast of Sumatra on Dec. 26, 2004 that killed more than 300,000 people."

Late in the evening on February 2, 2007 CTV.ca in Canada issued a warning about a window of increased earthquake activity, based on research being done by Canadian earthquake experts:
"Experts warn that British Columbia's south coast has entered a two-week window of increased probability in which a major earthquake could occur.

While the chances of that happening are still very slim, such an event could trigger a tsunami equal to the size and the strength of what hit the Sumatra-Andaman Islands in 2004.

Seismologists with B.C.'s Geological Survey of Canada made the announcement after measuring a series of minor tremors deep below the Earth's surface and along the Cascadia Subduction Zone -- a long, sloping fault that stretches from northern California to Vancouver Island.

The zone, which separates the Juan de Fuca Plate and the North American Plate, has a very large fault area which can produce large earthquakes with a magnitude of 9.0 or greater if a rupture were to occur.

"Where the Juan de Fuca plate is subducting beneath the North American plate, and where those plates are touching, it's locked," earthquake seismologist Alison Bird told CTV.ca."
B.C. enters window of increased quake risk

Late in the evening February 3, 2007, and early in the day February 4, 2007, stories started circulating that the 'silent' earthquake tremor traveling deep inside the subduction zone had suddenly stopped and the earthquake danger was over. Later in the day, February 4, 2007, Canadian news stories were once again circulating about an open window of increased earthquake activity for the southern part of British Columbia.

One of the troubling parts about the news story, is that there is hardly any mention of the risk facing areas in the U.S. It appears the media in the U.S. is being silenced; being told not to carry the story. Those in the Pacific Northwest, on the United States side, are equally at risk should a GREAT earthquake strike the region, yet, the American people for the most part are not being told about the heightened risk they are facing.

Is pressure being put on the Canadian geological services to silence, or lessen the danger risk? It has happened in the past with other geological services, such as the European Mediterranean Seismological Centre, so it is possible with Canada.

There are a lot of 'jack boots' working for the U.S.G.S. and the U.S. Government these days, and they don't like it when one of the other geological services says and does things that don't conform with the 'god-like' manner (we are superior to you attitude) of the U.S.G.S.

Similar types of disinformation surfaced when a massive tectonic movement took place in Indonesia on November 2, 2002, just a day before the massive Denali, Alaska earthquake inflicted a visibly big surface tear through Alaska.

A massive earthquake may, or may not, strike the Pacific Northwest - southern British Columbia region in the time period being predicted, but it is going to happen. It is not a matter of IF it is going to happen, it is only a matter of WHEN it is going to happen. With geological and climate instabilities increasing around the globe at a heightened pace, the event is likely to happen sooner rather than later.

The climate instabilities risk was added, because the melting glaciers and ice caps are adding water to the oceans, which is in turn is adding an increased weight load, and this is a situation that is further weakening already weakened tectonic plates. This in turn causes increased geological instabilities around the world. It is one natural system impacting another natural system, and one of the reasons global climate changes are such a danger.

The Pacific Northwest - southern British Columbia Cascadia region continues to be an area at risk from a GREAT earthquake. An earthquake that will in turn very likely cause a catastrophic tsunami, and very possibly set off a chain of volcanic eruptions on a scale not seen in modern recorded history.

The Earthquake Event of November 2002 - Forerunner of the GREAT Indonesian EQ (Earthquake)
Sherwood Ensey

Updated: August 6, 2005

In November 2002, an article was published to the old Earth Changes Central Yahoo group Email format about earthquake information being swept under the rug. The article was also published at rense.com. In addition to that article, another article was published about an unprecedented earthquake event that took place on November 2, 2002, just a day before the massive November 3, 2002 magnitude 7.9-8.0 Denali, Alaska earthquake.

The primary epicenter of the large scale event that shook ten's of thousands of square miles on November 2, 2002, was situated at Latitude 2.997N Longitude 96.082E - NORTHERN SUMATRA, INDONESIA.

The epicenter of the GREAT earthquake of December 26, 2004 that caused so much damage and death over a widespread area of the Indian Ocean region, was located at Latitude 3.27N Longitude 95.82E; roughly the same area as the November 2, 2002 unprecedented earthquake event that was reported on by Earth Changes Central in 2002.

The signs and indicators for a GREAT earthquake striking that region, and/or the Middle East to Balkans region, has been manifesting itself very clearly for quite a lengthy period of time. It is hard for me to believe that the "so called earthquake" and "geology" experts missed the warning signs that were manifesting itself right before the experts. Nature was giving the experts one warning sign after another, yet the experts appeared to have missed all of the signs and indicators they were being shown by nature. [There is some strong speculation that many experts knew the GREAT earthquake event was coming, and it was going to be a sooner rather than later event, but were being forced to remain silent regarding the information and data that was in their possession.]
