Mitch Battros is a little hyped up here with the assumption that a Cascadia Subduction Zone earthquake is underway. Now I am not saying this is impossible, however there are other scenarios. We are near a Cascadia Subduction event, but near is a relative term. It could come now, it is likely it will come with the bigger changes. A Cascadia event is on the level of the Indonesian even of 2004. A full blown Cascadia earthquake would be 500 to 700 mile upthrust event from Eureka California to Vancouver Island BC off the coast. It is possible that an event could happen that would cause the rupture of only part of the fault north or south but this feels unlikely, as when you check in with the earth mother the pressure is very high there.
The seismic activity being detected could be related to an event of that magnitude but it could just as easily be connected to a Puget Sound earthquake separate from the big subduction zone. The Puget Sound area is capable of large events by itself. Spirit has always held out a possibility of an 8.4 epicenter underneath Puget Sound. At the time I first shared this information way back in 1989, I was met with a lot of resistance. I was told there were no faults under Puget Sound. Since then more than one have been found and one very large one considered active goes across the Sound east west through downtown Seattle and out to North Bend (along I-90). The experts say they think it is capable of a 7.6 – 7 .7. http://earthquake.usgs.gov/regional/pacnw/activefaults/sfz/
In this map the north south fault right up the middle of the sound is the one spirit always talked about having the probability of a break with an 8.4 With the epicenter being just south of where the number 1 is on the map. Right out from Elliot Bay (Seattle downtown)
Another possibility for these tremors could be activity further awakening Mt Rainier. Mt Rainier is just Southeast of the most southern area of the Sound. The city of Tacoma is built on 400 feet deep mud flows from Mt Rainier. Rainier is a more powerful volcano than St. Helens and has been steaming for years.
The point is there is a whole series of possible big events that could hit the Puget Sound area that are not related to a giant megathrust Cascadia Subduction Zone 9 or 9+ event. That being said, we will be having such a Cascadia event before all is said and done as well. It may be a separate event but will more likely be tied into the series of large events that are part of the primary earth changes.
Earthquake Occurring at Cascadia Subduction Zone

Reports are now being filed by the Pacific Northwest Seismic Center, indicating ongoing tremors measuring moderate to strong levels over the past two days. The location of activity is positioned in the southern Puget Sound area of Washington State.
Wendy McCausland and Evelyn Roeloffs of the Cascade Volcano Observatory report that their analysis of seismic instruments south of Olympia, WA — does show a subtle signal that may be the beginning of an anomalous strain event.
Earlier in the week, seismographs in the southern Hood Canal area began recording bursts of low-level shaking associated with what is called an episodic tremor-and-slip event. This ‘slip’ event is likely to continue along the North American plate that lies under much of the Pacific Northwest. This NA plate is compressed by the Juan de Fuca plate where the two meet just off the Pacific coast. This is the Cascadia Subduction Zone.
The ECM team will continue monitoring on going event and report them as they occur. Be sure and check back with us often over the next several days.
The Last Cascadia Subduction Zone Mega Quake – January 26th 1700
Scientists believe the next Cascadia earthquake will be one of the largest on the planet measuring up to a 9.0 magnitude. The evidence of the great temblor 300 years ago was discovered along the coast of Washington and Oregon by Brian Atwater, a U.S. Geological Survey scientist in Seattle.
When Dr. Kenji Satake, of the Geological Survey of Japan, heard about Atwater’s theory he realised that Japan could hold the answer. He explained that while 300 years ago is pre-history for America, Japan has written records of seismic events dating back to this time. What Satake was looking for was a special kind of tsunami.
One day the people of the Pacific Northwest will face a megathrust earthquake. So how big will it be? What damage will it cause? When will it happen? The difference today verses 300 years ago — is this time everyone is watching close.

Current Earthquake Swarms Could Be Precursor to ‘Cascadia Subduction’ Mega Quake
by Mitch Battros – Earth Changes Media
Something is happening deep beneath the Earth’s crust. There are currently three very active earthquake swarms occurring along the Pacific Rim. It would appear something “big” is brewing. If geological teams from the US, Italy, Germany, and Japan are correct in their suspicions, we may be witnessing the precursor of the feared, yet inevitable Cascadia Subduction Zone eruption.
At this time there are three major earthquake swarms occurring in the world, and they just happen to be along the Pacific Rim from northern Mexico to Alaska. The first is the ‘Cerro Prieto’ volcano and geothermal field at the Baja Peninsula near Mexicali, Calif. The second is the Clear Lake volcano; also known as ‘The Geysers’ geothermal field in northern California near Santa Rosa just north of San Francisco. The third swarm is at Atka volcano along the Aleutian Islands.

There is the Baja, California swarm at the ‘Cerro Prieto’ geothermal field. It began on February 9th 2008 with a 5.4 magnitude quake followed by over two hundred smaller quakes measuring 5.0 to 1.3 magnitude. There is no sign of this swarm letting up. The swarm at Clear Lake, Calif. known as The Geysers began just days after the ‘Cerro Prieto’ swarm. The third swarm at Atka Island, Alaska also began around the same time.

Sitting in the middle of this vast array of volcanoes which lines the West Coast of America up to Alaska, is the Cascadia Subduction Zone. The Cascadia Subduction Zone is a very long sloping fault that stretches from mid-Vancouver Island to Northern California. It separates the Juan de Fuca and North America plates. New ocean floor is being created offshore of Washington and Oregon. As more material wells up along the ocean ridge, the ocean floor is pushed toward and beneath the continent.

Large Subduction Zone quakes are the largest earthquakes in the world, and can exceed magnitude 9.0. Because earthquake size is proportional to fault area, is perfectly set for “the big one” which is often mentioned. The Cascadia Subduction Zone is a very long sloping fault that stretches from mid-Vancouver Island to Northern California. It separates the Juan de Fuca and North America plates.
Emergency Management Officials Prepare for Catastrophic Earthquake
This notice was released just yesterday March 4th. Regional emergency management officials are preparing now for the next big one. On Wednesday, March 5th over 50 local public and private sector agencies are testing emergency plans and communications by participating in a catastrophic earthquake exercise dubbed “Sound Shake ’08”.
Based on the Regional Fault Earthquake Scenario; a study written by the Earthquake Engineering Research Institute, the exercise will mock-up serious impacts to the region’s transportation and communications systems. Additionally the scenario plan includes extended power outages, utility disruptions, and impacts to the health care system.
