Cascadia Earthquake - "may be in the Magnitude of 7 to 8 instead of larger" | |
| gdwk User ID: 22306955  United States10/29/2012 07:15 PM Report Abusive Post Report Copyright Violation | This statement was made by Robert Dziak Associate Professor at Oregon State University in an Article Published in a the Geologist Journal. [link to www.sciencedaily.com] He as been working with data which was formerly classified by the US Navy. In my opinion the recent Earthquakes 10/28/2012 which occurred at Queen Charlotte Islands validates his theory. Queen Charlotte Islands experienced an Earthquake M8.1 in 1949 which was the largest ever recorded in Canada. The Earthquakes on 10/28/2012 were M7.7 and M6.3 with a swarm of earthquakes of Lower Magnitude. If the Earthquakes on 10/28/2012 had been larger than M8.1, I would question his statement that the "subduction of the northeren portion of the Juan de Fuca plate beneath the North American plate may be slowing and eventually cease". A review of Earthquake History shows that the Largest Earthquake to occur in Washington State is M7.0. The Largest Earthquake to occur in Oregon is M6.8. There are others who post on GLP who predict earthquakes as strong as M9.0+. There is no evidence to support such a prediction.  Herman says No Doom for the Northwest. |

It spread across the entire Pacific Ocean, with waves measuring up to 25 meters high. The first tsunami arrived at Hilo approximately 14.8 hrs after it originated off the coast of South Central Chile. The highest wave at Hilo Bay was measured at around 10.7 m (35 ft). 61 lives were lost allegedly due to people's failure to heed warning sirens. Almost 22 hours after the quake, the waves hit the ill-fated Sanriku coast of Japan, reaching up to 3 m above high tide, and killed 142 people.

Atwater and Associates published in 2005. A review of the Book is published in The Science of Tsunami Hazards, Vol 24, No. 1 Page 49-55 (2006). [link to www.tsunamisociety.org] In the Conclusion the Author States: "potential magnitudes may have been overstated." "The major conclusion linking the ""orphan"" tsunami in Japan to a Cascade megathrust, magnitude 9 earthquake is based on conjecture and peripheral circumstantial evidence." "the book ..... still leaves us with the uncertainty of what really was the parent event that resulted in the destructive tsunami of 1700 in Japan." "the book is a possible scenario but not necessarily what actually happened." "absence of adequate historical or geological data to work with and sufficiently link the two disaster events." Earthquake History since 1900 shows the following: Largest Earthquakes to occur in each Location since 1900: California - Gorda Plate - M7.2 1980 Oregon - Juan de Fuca Plate - M6.8 1910 Vancouver Island - Explorer Plate - M7.3 1946 Washington State - Juan de Fuca Plate - M7.1 1949 The Book Review and Earthquake History is further confirmation that a Future Earthquake "may be of the Magnitude of 7 to 8 instead of larger". |

The Cascadia Subduction Zone is relatively small compared to other Subduction Zones. The Velocity of Movement is quite small - 26MM per year. The Cascadia Subduction Zone is composed of (3) plates - the Explorer Plate, the Juan de Fuca Plate and the Gorda Plate. The Pacific Plate Subducts under the Okhotsk Plate where Japan Rests at a rate of 95MM per year. Whereas Japan can expect large earthquakes periodically, the Cascadia Subduction Zone is simply too small to generate an Earthquake Larger than Magnitude 7 to 8. [link to upload.wikimedia.org] |

The Scientists who are predicting a Magnitude of 8+ for Cascadia are in variance to Professor Dziak of OSU. He works at a Research Lab located in Newberg on the Oregon coast. He has studied the Cascadia Subduction Zone for more than (10) years. He made the statement which is the Subject of my Thread that a Cascadia Earthquake "may be in the Magnitude of 7 to 8 instead of Larger". The Pacific Plate which subducts under the Okhotsk Plate is much Larger than the Explorer Plate, the Juan De Fuca Plate or the Gorda Plate combined. The Velocity of Subduction of the Pacific Plate is also approximately (3) times Larger than the Cascadia Bubduction zone. Japan can expect periodic Large Earthquakes. I support the opinion of Professor Dziak. |

The Largest Earthquake to occur in Washington State was a M7.0 in 1949. Professor Robert Dziak of Oregon State University has stated that the Tectonic Plates in the Cascadia Subduction Zone are Moving. The Tectonic Plates need to Lock before there is an Energy Buildup to create a Major Earthquake. In my opinion a Major Earthquake M7.0+ will not occur in Washington State anytime soon. |
