What might really be happening in Washington State?

reply to post by PacificBlue


I've always given a great deal of merit to the Indian 'stories'....perhaps the most acurate form of historical data for this area dating that far back.

On that note, Puterman just sent me a link to a recent article found by another ATS member (probably posted here on ATS somewhere already, I am sure) that is quite interesting.

Monster Earthquake Looms....


So to go totally off-topic, I am wondering if any of my friends here are affilliated with or have personal knowledge of endocrinology? I need some help in this area, so if you think you could give some advice, please U2U me.

Thanks, that article is interesting, and it is also interesting that the First Nation Village is moving to higher ground. I agree that the Indian stories are the most accurate history of this area that we have. Some of the stories of tsunamis and floods that the Indian legends talk about, make it sound like entire areas were underwater for a while, so I hope that it is not time yet.

Also, the simulation video was scary, as I am currently residing under one of the big red circles. But I guess it is good to know what may happen, so one can kind of be prepared. I picture the Portland metro area looking a lot like Christchurch if we ever got a really big quake in the right spot, or maybe even worse.

So not a whole lot to talk about on this thread for awhile.....until today.

Just had a 3.6 shallow quake about ten miles from my house! (about an hour ago) I was outside when it happend, hiking around in the wilds behind my house. I heard what sounded like an explosion from a distance, with some resonation in the ground. I thought it a bit odd.....like an explosion, but with a different quality. If it was a quake did cross my mind, but more so that it might be Baker or Glacier peak (that are both about an hour from me) because of the boom quality. I made a mental note to check the seismos when I came inside, but my quake alert on my phone got me about a half hour later first.

I have asked PNSN Director John Vidale on the PNSN facebook site about it. If there was any different quality to the signal. Perhaps it is just because I was so close that it didn't seem like a typical quake.

Any local ATS residents have an opinion or want to take a look at it? To my untrained eye it seems a little odd...but nothing obvious.

Hmmmm...no responses?

Oh well.....guess it was nothing too unusuall. Most likely just due to my location (being so close)

On another note, there was a nice sun halo yesterday. Perhaps all these halos mean Spring is finally here? I'm always trying to come up with new ways to photograph them.

reply to post by westcoast


Now that's a cool picture!

Here's a suggestion, do you have a pair of HD sunglasses? Try taking a picture thru the lens of the glasses. I had on a pair not too long ago and looked at the sun, there was a halo that I could not see with the naked eye. Worth a try.

Unfortunately I can't read graphs or anything like that. But I had a 3.6 very near me last year in MD. boom, crackkkkkkkkkk....thud thud thud deep booming with shaking. If it hadn't been for the incredible shaking that followed, I would have thought one huge lightning bolt had struck one imaginary huge tree right down the street. The boom was loud and that crackkkkkkkkkk noise was like the ground ripping apart. But when I went out the next morning all was fine, there was no huge fissure one might expect to see after hearing the ground crack like that. Does any of this sound familiar? What exactly struck you odd?

Okay, so I haven't posted on here in quite some time, but I think I need to update.


There has been discussion on other various threads regarding the recent moderate-sized quakes occuring off-shore Vancouver: (the most recent about an hour ago)

SO.....the problem with this, is it seems that USGS is only reporting quakes that are above a certain magnitude. Now this has come up before. I don't recall all the details, but I know I have discussed it in the past. Typically, USGS is triggered at 4.5 and above, but sometimes they'll be watching and listing some smaller ones (over 3.5) for the region because, well....perhaps because it is the Northern edge of the Cascadian subduction zone and may be the only warning we get for the next mega quake???!!!!!

*sigh*....I don't get it. Is it a border thing? Is it an issue with the two countries working together? Or is there really no issue other than that we, the public don't see the monitoring or communication going on between the different organizations? Because it really bothers me that USGS/PNSN do NOT list these quakes. I know they are watching. John Vidale (director for PNSN) has been talking about them on the PNSN facebook site and even provided a link to where we can see the REAL action going on there...it's kinda scary:

Canadian site for quakes near vancouver


There has been a MASSIVE amount this past week. I haven't counted them yet...but I will. I'll guess it's around three dozen or so.

If we were to move this swarm (yes, it is most definately a SWARM) to the region that we often see some 4-5 mag quakes off-shore Oregon, people would be literally throwing the red flags and running around. But because it is nestled up at the northern edge in Canadian waters.....we hear literally NOTHING about it. It makes NO sense! Now..it is quite important as to whether these are originating from the subducting plates, or another well-known fault in the area that is a strike-slip. Problem is...the USGS and the Canadian site don't even have the quakes in the same place. They are spread around a bit and have different depths. So...what then? Are they coming from both? I dunno, but it would be nice to have some more discussion on this!

What say you??

Thought I'd share my view of the super moon tonight with you all. It was a good one!!

reply to post by westcoast


Great picture, I really like how you can see the tops of the trees, that is neat. I was glad that it was not too cloudy last night to see the moon. And today is sunny and warm, finally, hope it is nice up where you are too!

Well I managed to get a semi-decent picture of the venus transit! I got this from my back yard through a thin layer of clouds...

(You can see some sun spots too!! )

Thank you! I am really glad you enjoy them!! I just think it's fun to share how things look from this part of the world...it's a beautiful place we live in.

Hello friends!

WC... was wondering if you saw this?

INFO

Wow. Has it really been FOUR months since I last posted???!!! Sorry that I didn't answer those last couple of questions...I just now saw them.

I have obviously been busy and not around *here* much. Also...not a whole lot of activity to discuss recently (which is good).

I felt a need though to address the 7.7 quake that occured North of us up in Canada. I feel there may be some significance for us here in the Pacific NW. I also just wanted to check in my friends and see what you think.

I want to direct your attention to a report made by PNSN Director John Vidale HERE

Most pertinent to us:

This earthquake likely applied some additional stress to the faults we are concerned with in the Puget Sound and will have local aftershocks that are prominent for weeks. As usual, the chance of further seismic activity in the immediate vicinity of this earthquake will be higher than normal for a while, but does not rise to the level at which any actions are warranted.

There was at least one after-shock that drifted down South near Vancouver Island and possible into the subduction zone. This is what we need to be on the lookout for.

Be safe.

ETA: I also want to just mention that my *big* quake dog is extremely snuggly today. He is normally affectionate....but tonight he just keeps staring at me and seeking closeness. A bit odd. He hasn't done that in the past for quakes, but that it worth sharing.

I've been waiting to see if this thread popped up soon! I feel like this quake has a whole lot to do with down your way WC. I have no idea why I feel that way, but I've never really felt like when pm reckoned it'd be another 55ish years until we see another 9+ that I agreed, when it came to the PNW at least. I've said so many times on here how I'd love to visit that neck of the woods but something is stopping me from visiting. I keep telling the Mr. "after the quake we'll go". Just a feeling!

Side note, where has TA been lately? I don't know, I just feel this needs more watching for some reason.

I missed this post Westcoast, but I definitely agree that it has significance to the PNW area.
The tremor restarted in your neck of the CSZ right around the time of the m7.7, and is continuing, although not as strongly, today. And the tremor at the southern end of Cascadia has been ongoing for 10 days now.

I've been looking at the GPS data and the plate boundary strainmeters. I'm trying to self-educate myself (which is a very slow tedious process--I am so very thick-headed at times ), but I feel like something is going on in the southern Olympics/northern Oregon coast area. I'd love to hear what the pros are seeing.

I'm watching this beast, too. Stay safe.

I agree...energy has shifted. It has to go somewhere.

The longer the area goes without another moderate sized after-shock, the more unselttling it becomes. I realize that not all large quakes have after-shocks, but this one obviously had a huge swarm right after. It abruptly dropped off after the 4.0 yesterday that was very shallow (1.1km) and now nothing over 4.0 to be registered by USGS.
