They are reporting quakes off Vancouver Island and Seattle on the news this morning, both in the 4+ range.

It has my attention right now, seeing as I live in downtown Seattle... I hope this activity isn't building up to something large..

Me too. I'm just north of you
I got the disaster prediction app from QuakeWatch.net
I like the alert maps . So it's showing a risk for your area. They have a 70-80% accuracy rate

Not to alarm anyone though, but it's good to be in the know , just in case. Since we are due for a big one and then we are also surrounded by volcanoes

Article from today

Slow Slip Earthquake season raises risks of The Big One

B.C. is headed back into another one of its riskier seismic seasons, raising the risk of "The Big One," earthquake experts say.

Every 14 months, the Cascadian subduction zone — which runs from northern Vancouver Island down to northern California — experiences what seismologists call a "slow slip."

This year's slip has already kicked off underneath Washington State and is expected to reach B.C. any day now.

The phenomenon happens when seismic stress shifts onto the fault area where the Juan de Fuca and North American plates lock together.

That causes thousands of mini-tremors and heightens the likelihood of a major earthquake event in B.C., according to seismologist Alison Bird.

"If that locked zone is close to critical, and you add more stress on to it ... that could trigger, theoretically, the 'megathrust' earthquake," said Bird, who works for the Geological Survey of Canada.

As for how much more risk that is, she says it's been likened to the increased risk of driving in rush hour traffic.

"Going for a drive in the country on a Sunday, you're not that likely to be in a car accident. But if it's rush hour in Vancouver and there's a game on ... you're more likely to be in an accident. You're not necessarily going to be, but the probabilities are higher."

Another 4.9 reported off Port Hardy. Yesterdays 4.8 was in the same area, plus there was the 4.2 near Seattle. And this is at the same time that the tremor/slip is beginning again.

I am in pain! My PCs motherboard is not well and I only have the laptop which means no automated earthquakes on the other QuakeWatch maybe for a week. The pain is most likely caused by the impending expense! In addition we had no internet for the last 24 hours (back on in the last hour) and it felt like the world had ended

One has to say one is not a happy bunny right now!

a reply to: PuterMan

Awwwwww Puters, I 'm sorry to hear of your pain.

I had some problems on my computer the last couple of weeks. (that's why I haven't been here)

I was looking at the pain of having to buy a whole new PC.

Turns out it was "Chrome" acting up.

Now I have to use Firefox to print. Weird.

Thank goodness for good IT people.

Hope things get better.

P.S. I think you had some large quakes north of you. But Only one was reported. Jerks.

So when did these slow slip tremors in the PNW last result in a magnitude 6 quake?

Tis the season muzzy. Every year. No 6's that I know of. But I'm watching too. Port Hardy have been very active for a week or so. Sorry on phone can't link.

Then there is no need to worry about them.
Same here at Taupo, none of the regular swarms ended in a big quake.
Could be the same scenario, lots of small tremors release the stress.
Perhaps the M9 will never come.
Few big quakes have a lead in, Honshu 2011 and Chile 2015 the exceptions
and they had heaps of M6s and 7s beforehand
taking a 1000 tremors with magnitudes so small they can't put a size on them and throw in a M4.2 and a 5.1 hundreds of miles to the west doesn't mean the monster quake is about to happen.
If there were 1000 M4's and a couple of M7's then it might be time to Get out of Dodge (Tacoma/Seattle/Vancouver)
The old adage that "if there is no activity, be worried" may apply to the pNW.

a reply to: violet
the "experts" don't know nothing, they are only guessing what might possibly lead up to a M9, something that last happened 317 years ago, I have not read anywhere that the local aboriginal people reported swarms of quakes prior to 1700, they were the only folks around the PNW then.

Now that I have spent some time studying the area.

I realize, that getting excited is not the way to be.

I whole heartedly agree with you.

I have learned to chill, and look at the information that is available to me.

I have to thank Putermann and you for that.

(((HUGS))) to both of you.

a reply to: crappiekat

P.S. I think you had some large quakes north of you.

I felt nothing! Where were these quakes? Who said they could have quakes north of me? Being serious for a moment, I can't see any. Was this Iceland?

Thanks for the 'hug' by the way.


Found on one the Northern Mid-Atalntic ridge. Is that the one?

That one was 20 deg south of me (Lat 35 annd we are about Lat 55) and about 26 deg west of me (lon -35 and we are lon -9)

*waves Hi to PuterMan*

Hey sugarplum, haven't seen you around these parts in a while (different time zones)... good to see you're still alive and kicking and keeping up with these earthquake threads !

I still like to pop over to your blog once in a blue moon to see how that side of the pond is doing and read your weather/climate posts and other fun stuffs.

Funding Cut? Fell asleep at the wheel?

nothing for the 3 mag 6.5+ quakes this month

Howdy all. I live on the East coast of Vancouver Island, approx mid way up the Island, I havent felt any tremors here. Most of Nanaimo is built on bedrock, but the whole city is undercut by coal mine shafts. If/when the big one hits, I fear the bedrock might just crumble due to all the shafts, like swiss cheese. Anyhoo, not much we can do but keep our finger crossed...

a reply to: PuterMan

Hahaha..

I was talking about the one's way up there in the North Pole.

I follow Suspicious Observer's daily video's and he mentioned them.

I hope you get your computer problems worked out. I know $$$$

a reply to: muzzy

Maybe he went out to get smokes and beer and got lost.

a reply to: crappiekat

Haha possibly
GFZ is acting odd too
I'm getting a message some times
"the data shown if from stored case 809 hours ago" or something like that
Now I can't even get their page to open at all
both on my phone and my laptop
started getting that message yesterday
maybe it's time to delete some cookies or clear the cache or whatever it is called
I will try that

Following your thread is fascinating. Thank you for all the information (and discussion).

a reply to: Leanansidhe

Thanks for reporting those.

I sometimes miss the one's down under.

USGS are not reporting those, at this time.

Keep watching Japan.

Been active over the last 24 hours.

This is the latest event.
