Picking up some activity on Cascadia- 5.8 Quake but...
page: 3share:
I'm in Vancouver, when my wife gets home with the car I think I'll run out and pick up some water and a few supplies, just to be safe. We're about
200' above sea level here, so should be ok.
I just want to recap the quakes in order:
5.9 Off the coast of Oregon 2015-06-01 11:11:31 UTC-09:00 10.0 km
4.4 Off the coast of Oregon 2015-06-01 05:46:34 UTC-09:00 10.0 km
5.5 Off the coast of Oregon 2015-06-01 01:46:27 UTC-09:00 10.0 km
4.3 Off the coast of Oregon 2015-05-31 22:01:20 UTC-09:00 10.0 km
5.8 Off the coast of Oregon 2015-05-31 21:52:41 UTC-09:00 10.0 km
Does almost seem to be building.

I might be wrong here, but aren't these quakes in the vicinity of that underwater volcano?

Oh ok thanks, but that means that the quakes are less then 100 miles (or less then 80NM) south of the volcano. Humm? Just thinking out loud here, but could the quakes be nothing more the magma flow movement? (like in Iceland just under the sea?)
Then again it could just be plate slippage. I'm only pondering since the weird winter weather here in the PNW was due to a warm blobby spot in the Pacific that was hovering over the volcano zone. Just planning my summer.

It would have to be a pretty big underwater volcano to have magma movement that far away, but you never know!
My personal thought is that they are not connected, but it could be another volcano for all anyone knows.

Not that this is my favorite source of info. But it has a map of quakes that led up to the 98 eruption. The info here pretty much sums up other
articles in one place. It looks like from the map the area from the recent 5.8 quake also had a quake in same location but was precursor quakes. What
says you TA.

Hey Olivine, where are we with the slip tremor cycles, should they be starting again soon?
I'm putting this out now just in case a giant earthquake sends a tsunami into my house and washes me out to sea.

Hey bunny there are 2 buoys in event mode. Data Buoy Center
Yay.
I am NOT telling my wife.
That last thing I want to hear is, "I told you so!"
For all the doomies it'd take a 7.0 or higher to trigger any tsunami warnings here.
Wow, there has been a lot of activity in the past 2 days around oregon. I live on the north tip of vancouver island so I'm definitely paying
attention. Not that I know anything about earthquakes, but the magnitudes being pretty similar seems kinda ominous to me. I guess we'll see.
If anything does happen, I'm most definitely running outside. It's faster to get outside for me than to get under the kitchen table. haha.

Maybe you could look at TA's posts and realize he actually knows a thing or two...nice contribution.
Thanks TA, I appreciate the relationship to the Japan side of this, and your awesome interps...you picked em a time or two

Ah well entirely my bad for not having reading comprehension. Some authors are better at helping me see the light than others...take from that what you will.

Thanks for the vote of confidence, buddy.
So I guess everyone realizes now that we got us a situation here. Those first two quakes did indeed turn out to be foreshocks to the bigger 5.9. Problem is, a 5.9 is still not far enough away in magnitude from the 5.8 or the 5.5 to give you any good news. Let's hope it ends there, but it might not. I'd stay prepared if I was you's.
If there is any good news at all, none of these are anywhere near the locked zone near the coastline. They are pretty far out at sea. But I have a feeling that when the locked zone gives way for the mega quake, it will be with no foreshocks or warning whatsoever. One day the upper lip of subduction will just not be able to handle the stress anymore and WHAM. It's probably going to occur much closer to shore than any of these quakes. Which means little time to prepare or run from the tsunami. Those who keep a dirt bike ready and have several paths well rehearsed will have the best chance of making it. Cause you may have less than 5 minutes if that quake is close enough to shore.

lol damn and here i thought you needed help crafting some doomporn. None needed obviously
Well if it hits the fan and you can make it here just remember, Spokane has an airforce base and airport. Might end being your only way out of the PNW. We got a right fine militia around here that'll keep ya safe, so just go looking for the Lightfoots...

lol, well it's really not doomporn. Regarding what I said in the post above it has to do with how other mega quakes like that in subduction zones usually occur, like down in Chile, Alaska, and other places. Sometimes there are foreshocks, but more often than not the stress just builds up so bad that it gives way in an instant. And there have been so few to no smaller "stress relief" quakes directly in the locked zone in Cascadia at all. They all seem to occur way out at sea on the Juan De Fuca. So the stress is building, and has been building for over 300 years. It'd be a good thing actually, if say a 7.0 hit in the locked zone near the coast and got rid of some of that stress. Might be some damage, yeah, but that's better than taking on a 9+ if that entire fault length ruptures at once...
