ALERT Magnitude: 7.7 West Coast of Canada

reply to post by NiteNGale2

I wouldn't think so.
I don't know what sort of earthquake this was and I know nothing about the terrain. I suppose it's possible for a quake to trigger a submarine landslide though.

Acording to the director of the PNSN (pacific Northwest Seismic Network)...you would expect to see a strike-slip quake from that specific area, but it is looking more like a thrust (as in from a subduction zone).

Seems to be a little confusion as to why this type of quake...but there are apparently a lot of faults around there so lots of potential for different kinds.

What gets me is the pattern emerging from the after-shocks.

third tsunamis wave is usualy the worst

Tsunami mythology.
With these beasts there really is no "usually". There are too many variables.

yes true .. so until the tsunamis alerts are lifted
we cant scream victory just yet

I'm worried about the pattern of aftershocks too and how they are clustering closer down the fault line than around where the epicenter was. Could this be a trigger for the Cascadia subduction zone?

another 4.2 followed by 5.3

That's 20 aftershocks by the way....

Yes...that is my fear. I think the initiall reaction was..oh, this is going to be a strike-slip quake that will not affect the load on the Cascade subduction zone. BUT...instead it appears to be a thrust quake and all the aftershocks are lining up/down the fault, only a hundred miles or so above the believed Northern edge of the subduction zone.

I don't like that.

I predicted earthquake an hour before proof is in my tweets at twitter

Yeah, I've been staring at the Quake map for too long. All roughly the same depth too.

Aftershocks, aftershocks, aftershocks. Unfortunately my whole life they've been droning the big one is coming in my ear I can't help myself.

4.4 now too.

Cool bro.....I predict a Mag 4+ 100K from QCI. Watch, I'll get one too.

Ahahahahahaaaaaaaaaaaaaa, and just like that 4.6 in my exact criteria just now.

i predict you that you will get a reply to your reply
oh wait

can you post a screen shot of this particular tweet ?

I noticed that too. The 7.7 was at a depth of 17.5km in the middle of the Haida Gwaii and all the aftershocks are around 10km deep and on the fault line.

That makes it 22/23 (depending on what website you look at)

Keeping things rolling here. 23 quakes ranging 4.1-7.7 Not bad considering this area hasn't had anything register in the last 7 days... I kind of want to go look when the last 2.5+ was. Or even when the last was period ha ha.

Even though PNSN has stated that the last ETS is over, I've continued checking out the tremor map. I have noted that some activity seems to be occurring on the southern edge of the subduction zone. My understanding of ETS is that the slow release of energy in the deep eastern zone of the plate might lead to more stress on the more shallow, locked western side of the plate. If there is something still occurring in North Cali, do you think that the earthquake in Canada (the northern edge of the CSZ) might be beneficial? Something that released the stress so that the subduction zone itself is under less stress?

I hope that makes sense.

who felt it?

closest populated city?

I was changing the filters at USGS and there has been no activity with magnitudes larger than 2.5 in the Haida Gwaii (hell the whole Cascadia subduction zone too) in the last 30 days.

Are we fueling each other in this? Ha, ha, where did Phage go, he's usually one to smack sense into ATS Doom-seer's.

Probably but it doesn't hurt to be cautious... right?

4.4
