Good cause for worry.
Owner of property next to ours had harvested a large number of Jeffries, and left one that was about 175’ tall standing alone in a clearing, big tree, and during a wind storm last winter it snapped off about 25’ above the base, where it was about 30” or so in diameter. Sounded like a .44 being fired, and dug itself a good hole in the mud.
Are you a geologist? Or a Seismologist?
Nope.
Just a nerd!
(I do computers on and off)
winnie - the subduction zone has been loading from multiple locations. No one fault/quake will load the whole plate.
I only commented in regards to your statement that you gained your ‘information’ from some webcorders. I certainly hope you look elsewhere.
Not saying that at all zilla...
A forequake of this magnitude can signal that the tension/load is increasing in such a manner as to snap. Even more suspicious being a strike slip. It matters not..for if it is a prequake....who cares for the main shock can not be forecasted nor timed.
I see you are the same Zilla....lol
Have a great night bud...going fishing in the Atlantic tomorrow...lol
Door knocker?
Maybe. But not likely. Too shallow (only 14 miles).
I’ll explain a little bit more of what I know and heard about what to watch for.
I talked about the Nisqually quake above and said it was very, very different from normal type quakes. Here’s why.
We have regular slip quakes where two plates slide against each other, like the San Andreas fault activity. They can be very damaging, especially because the effect is to basically displace the foundations of buildings horizontally away from where the building is!
We have subduction type events where one plate gets jammed underneath another plate. Thousands of square miles of plates can get moved, ocean floors and coastlines can rise and fall. There can be some horizontal movement, but alot of the movement is up and down movement.
The Nisqually quake wasn’t either one of these!
Imagine you are making pancakes. You get ready to use a spatula to flip over a pancake. You push the spatula underneath the pancake.
You just caused a pancake subduction earthquake!
But imagine that instead of using a spatula, you try to use lets say a graham cracker or something. You are able to slide the graham cracker a little ways under the pancake then...
the cracker snaps in half because of the weight of the pancake.
That’s what the Nisqually quake was. The Juan De Fuca plate, the part that has already been jammed underneath Washington state, snapped and broke because of the weight above (and remember as it goes farther inland it gets pushed deeper and gets hotter and melts).
The Nisqually quake was quite deep, and there are a few faults in the area, but it wasn’t technically a slip quake or a subduction quake per se. There is a special name for these types of quakes and I thought it was “Benoit quake” but I think it’s something else.
I saw a bunch of interviews of people after it happened and almost all of them said the same thing - the ground shook, but mostly in an up and down type motion. One guy in downtown Seattle said it felt like his building just suddenly dropped straight down a foot or so.
I was driving and didn’t even feel it! And no damage to my house.
Anyways, just an FYI...
All of Canada.
Although I could probably stand parts of Alberta where most people would be against it.

Thanks for the explanation. I regularly check USGS earthquake sites but was unfamiliar with Webicorders.
I’ll fill the bath tub after the quaking stops. We’re on a gravety feed.
They feel that quake will be in the Cascadia seduction zone and could effect the San Andreas as well being they connect to some degree. They think it will be as large as the one in Japan and could possibly trigger one or more of the volcanoes to become active. The quake today, as others have noted, was on the north end of the Cascadia zone.
All of us who live on the west coast should be prepared anyway. I am 20 miles SSE of Seattle. Where the epicenter is located will determine how much damage it will do to us. We have lots of food and water for just such an event plus an emergency kit in all our vehicles incase we are not home at the time.

We have news out of Cornell University that sustains the view that Elenin is playing a direct part in causing large earthquakes. Professor Mensur Omerbashich is saying that his “georesonator concept in which tidally induced magnification of Earth masses’ resonance causes seismicity.” This trashes NASA’s assertion that the humongous earthquake we saw in Japan and before that with the ones in Chile and New Zealand were coincidental with alignments between Elenin, the Earth and the Sun. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
The earth’s seismicity can arise as a natural response |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
Omerbashich demonstrates empirically that “all strong (~M6+) earthquakes of 2010 occurred during the Earth’s long astronomical alignments within our solar system. He shows that the same holds true for all very strong (~M8+) earthquakes of the decade of 2000s. He asserts that the “comet C/2010 X1 (Elenin) has been adding to robustness in terms of very strong seismicity since 2007. Elenin will continue intensifying the Earth’s very strong seismicity until August-October, 2011.” |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
It seems like every time Elenin lines up with Earth and another planet or the Sun we have an earthquake, the nearer Elenin gets the bigger the earthquakes. |

Now of course we have many earthquakes and if we showed them all, this chart would then lose much of its meaning. The 9.1 earthquake in Japan though will never lose its meaning and it happened on cue with an alignment with Elenin. |
not to worry, Elenin got zotted by a solar flare a few days ago and is in the process of disintegration.
I noticed today that there have been no aftershocks to yesterday’s quake. None. That is really odd. What does that portend, if anything?
After the Japan quake scientists stated that three days prior there was a large emission of energy from the epicenter.
Are there any entities monitoring such energy emissions off our coast? Or will the scientists just bring it out after the fact?
We will find out there is no way to predict it.
Well I would think any known cause and effect type event would have a degree of understanding to allow for prediction but yeah Earthquakes as they stand now....no.
But as we move on....as with volcanoes there are patterns and signs that help you at least understand there meaning.
Just noticed an aftershock for this quake. 4.1 around 0430 local today. Whats interesting is post #10 above upgraded to show the recent quake.
Will be interesting once they release the data on the quake...!
Thanks for bringing it to my attention!
