I really hope that is what it is. Because that kind of makes me a little uneasy.

Thanks for posting about the glitch factor.

And oldtimer2......get the heck out of this thread. We do not appreciate the likes of your kind of folk up in here

Yes, makes me nervous too. I'm in Vancouver. I was ready to head to Costco and buy additional water and suppies, and if it's not a clitch, I still will. Please post as soon as you know. This is important!

Hi John. Any more info from Mr. Wech?
I went to the tremor map and noticed that when I run my mouse over the times, the epicenters seem to jump from one cluster to the next, and the next, and so on...south to north then back again. It does look suspicous.

Just out of curiousity, do you recall ever seeing a 'legitimate' spread of tremor along the CSZ , similar to the June 10th map? Did it/would it pique your interest, or cause alarm?

I tried to pull up the recent epicenters for yesterday and today, but could not manage this simple task


When you get a chance, would you so kindly post an updated map of the epicenters for the last two days??

Yesterday, June 11th shows zero tremor activity. And the 10th still looks like this:

(click to enlarge)

The people at PNSN suspect some sort of error in processing on the 10th, but I haven't read a definitive answer yet. I suspect they are still checking their system. Hope this helps.

Hey guys, just noticed your thread.

The increased seismicity along the CSZ may be related to the coverup of quakes along nearby plate boundaries; here are two from today that were dropped from the ANF site and never even picked up by the USGS just north of the CSZ:



And one from yesterday:



And more, there is no major plate boundary here that we know of, it could be a stretch zone, and it could influence the CSZ:



All these Pacific Ocean quakes have disappeared from the ANF website and never showed up on the USGS. Yes, as you probably know, there would have to be at least three seismic stations recording the same quake in order to get a triangulation - what is the chance three stations would get identical errors?

If this is the case it totally disgusts me. Thanks for the heads up!

Can any of our resident experts confirm the reliability of the source with this info??

Could you post a link to this website.

It would be greatly appreciated!!

Sure, here it is:

anf.ucsd.edu...

Remember how earthquake reporting works, for those of you who don't know, some may, in order for an epicenter to show up on a map like the ones I posted above - at least three seismic stations must have recorded the same seismic wave - they need at least three recordings to triangulate on the epicenter - and it is hugely unlikely three stations would make the same error. Of course EQ's can be upgraded or downgraded by a couple of decimal points, but this is not the same thing - these EQ's are being taken down from the ANF site and not even showing up on other sites.

The main question to ask is why?

It looks like the slightly concerning pattern of ETS from 06/10/2012 was due to a malfunctioning computer.

Aaron Wech, the creator of the tremor page software found here just posted the following blurb on the PNSN facebook group page (login required):


Confirmed computer problems. The machine that I grab data from was apparently very very sick, producing data gap and errors that caused all sorts of problems for my codes. Things should be back to normal now, and the processing will be redone and website updated shortly.

Finally escaped some meetings, and got back to one of my laptops.

Aaron Wech has diagnosed the plague of activity on the 10th as an artifact of telemetry problems. Sometimes tremor activity seems to jump improbable distances in a few days, and sometimes much of the arc is active, but I've never seen the entire Cascadia arc light up on the same day for real.

Thanks John for the update on that....and thanks Oivine for your diligence!!


As to the other source, i really can' say. Perhaps someone else knows? I know quakes are sometimes dropped due to errors or explosions, but I don't usually see them disappear when they originate in the ocean. (moved, yes...location in the ocean is tricky) Curious.

Hi I live in Vancouver and was wondering if the stress build up may be less now on the Northern Cascadia fault area seeing we had a 6.3 last week and the 6.4 in Sept 2011?

I am a landscape contractor not a geologist. However, I feel all this activity is a little foreshadowing of big things to come.

I hope I am wrong........Oh........!! but I did stay in a Holiday Express last night. For what it's worth


Sure wish John Vidale would rear his professional head and spill some of his precious wisdom on the situation.

It's been a while since I posted in this thread, but I thought I would bring it back to the front page for some input, so here goes.


I've noticed that the GPS array situated across the Vancouver Island, B.C./northern Puget Sound, WA region has remained unsettled since the Mag 7.8 Haida Gwaii earthquake 03:04:11 UTC October 28th.

The map below shows the array. map source


Now check out the data.
This link will take you to the Latitude page--showing movement in the North-South direction. (sorry, the page is too large to provide a screen shot)
Almost every station shows a 15 millimeter (1.5 cm) movement to the south over a two-day period. Then a 10 mm rebound to the north the following day. (The best I can tell, this movement occurred over the 22nd, 23rd, and 24th of December.)

Does anyone else think this movement is large? Looking at the graphs prior to the end of October, the GPS positions seem fairly constant. Not stationary, but relatively calm. But to my eye, November and December look like a rollercoaster across the entire region.

Use this link to check out the vertical locations. Just about every station in the array experienced a 20 millimeter (2 cm) drop over the same time period.

No slow-slip (ETS) has been observed in the area over the past week or so, so it is not that.
Umm, I don't know what to make of it, but I wanted to share. Maybe over a longer time frame, these movements will look tame.

It seems that the slow slip has started again


Scroll down to the third story in the link I have posted.

These rumbles usually happen every 15 months. However, they seemed to have started early this time around and now are happening again.

Will try to track down all the details. Someone posted some awesome 3D maps of the quakes earlier this year, and am hoping they will do the same for this recent episode.

Someone from the B.C. area has reported a constant rumbling for the last 24 hours. That is why I posted this. It is posted on the godlikeproductions site.

Thanks for linking that article. I hadn't read it yet. I see westcoast has also linked it. I've also wondered about the potential for "the" big subduction slip during a tremor episode. It sounds like the pros are still undecided.

Looking at the realtime tremor map for the PNW, there looks to be a little tremor under northern California. I don't expect to see another full-blown ETS event under the Puget Sound area; the last one just ended on 12 October 2012.
