Quake Watch 2017

update on Kaharua Swarm posted by: muzzy
Went over 500 events yesterday at noon.

I made a couple of animations to see where it was headed
slightly to the south side of the Cone, but also scattered all over the area
Kaharua Swarm page
This is north of the massive June/July 2009 850 event Swarm when the Waihi Village had to be evacuated.
2009 Swarm
And south of the smaller 115 events Swarm at
Poukura Pa in Nov 2016

Well, It's that time of year again in the PNW.

Earthquake Season (Slow Slip)

We have had some great conversations here in Quake Watch about this. One of our members Olivine has posted some very informative articles here. If you go into the archives and look there is more information.

This article dated February 27, 2017 talks about the risk of a major earthquake in the Pacific Northwest caused by a phenomenon that causes tectonic plates to move.

It's not a long article.

The last slow slip event was in Dec 2015 so I don't see how it is "seasonal"
Seasons happen every year at the same time.
It is currently Feb.

Every 24 months, the Cascadia subduction zone, which runs from northern Vancouver Island down to northern California, undergoes what seismologists call a "slow slip."

weather.com...
24 months is not a season.

Here it indicates that it's every 14 months, which is what I have seen from a number of sources, and that's give or take.

Yes indeed, there has been some moderate action there lately.
I have been slack, 10 days since I last did a download from NIED
and 15 days since I updated E off Fukushima where most of these have been
Will get onto it today.

Well I quoted what CBC said on the linked text " increases the odds of a major earthquake event in British Columbia" off crappiekats weatherdotcom link when I opened it on my phone, it said 24 months.
That is why I mentioned it.
The original link weatherdotcom story still says 24 months.

I haven't got time right now, but someone could look through these and confirm or not whether this is fake news. I see 4 seasons on the list, so there is no "season" for these tremors.

I'm not saying that the tremors are not happening, I'm saying the CBC needs to get the story straight, and report the facts correctly, not make something that is pretty random in time seem like it happens the same time every year (or watever period).
So this has been recorded since 2003 by PNSN? hardly a long enough period of time to come out predicting the M9 is imminent.
What about prior to 2003? surely it didn't just suddenly start 14 years ago?
Probably been going on since 1700 when the last big one hit.

Just google and watch the show "Monster Quake, Are We There Yet," which was made after the Japan quake and tsunami, there is information in the program about the 14 month interval, which may include background information such as when it was first noticed, etc.

Nope, no puter yet. On Saturday the repair shop said they would order the motherboard in the next 20 minutes (having discussed which one with me) Monday I get a call to say the job will take a little long and the new motherboard had blownand the power supply was gone. (It was fine whan I last spoke to them)mSo I wnet in and spoke to the man doing the work. He said not the motherbaord had not come in as he had only ordered it that morning. And yes the power supply and everthing else was OK.

How I managed to walk out whilst still keeping my cool I don't know. Must be mellowing in my old age. A few years ago I would have shredded them.

Sigh! Never again will I be lazy and take a computer in for repair.

Thank you. Glad someone reads them. Make it all worthwhile.

Yep that's working fine.
It was just their own Web page was throwing up those messages for that day.
Seems OK now.

Its all very well living in the future, but you do have to pay attention!
One advantage of using Blogger to post the daily maps for japan is that when I get behind and then do a big update I can still set the posting date for back on the day in question, and the posts still come out in the correct order.
Only problem is that NZ is half a day ahead of UTC, so when you don't pay attention and the month flips over you can, as I did yesterday, the 1st March NZDT, post a whole load of daily maps that you can't see on the published site
The reason being that I "backdated" the date to March 18,19,20, and so on by mistake, instead of February.
Took me a while to realize why I couldn't see the dates in question Doh
All fixed this morning.

Seasonal. Ha. Stupid weather has messed up my observations. However, there is an earthquake in the mid-Altantic, and there's a storm atop the spot. This year has been super slow and I'm blaming the weather. I'll make a brief comment and cut it short before I starting raving and ranting. Last night, here in Southern Ontario, Canada, we had a thunder storm. Every couple of days we break a heat record. I remember being a kid, it was wasn't like this then. I'll stop.

Now, for something completely different. And almost insignificant. Europe and Asia jiggle a little in a little cluster.

Alaska seems to be saying hello. They could have a big one anytime.

Also, one last thing. I'm going to call the swarm of Northern Nevada over. There's been almost nothing lately. Challis had a tiny one.

Yes that's that Northern Hemisphere Warming. (Not Global Warming)
We have had the crappiest Summer in 30+ years over Dec-middle of Feb
Its come on now end of Feb. , but it feels like a mix of Summer and Fall, warm during the day (22C+) then down to 10-12C at night, heavy dew every morning.
that's that Southern Hemisphere Cooling. (Not Global Warming)
I blame the 2011 Japan M9 earthquake, threw the Planet off balance

That 5.7 off Namie Japan may just be another aftershock of the Nov 2016 M7.4, not a new series, hard to say it is right on the edge of the big aftershock group
I base this on the amount and location of aftershocks since the 5.7 2 days ago, and comparing with the previous aftershocks there.
NIED gave me 7 hours of data since the 5.7, will have to wait until tomorrow morning to get more
first image is the 7 hours of aftershocks since the 5.7


where it is in relation to the E off Fukushima series


where it is on the edge


different fault?, same series? hard to say

there was an uptick in that southern part of the 7.8 aftershock series in the last few days.
As with Japan I hadn't logged them, too busy at work,up until today.

If the location is correct this is on a Fault that has previously been unaffected since the 7.8, only 3 quakes on the Blythe Fault since the 7.8

where were the 15 x mag 5's and the Mainshock and the 6.2?

finger points to that last 5.7, one of the 3 x 5.7's

E off Fukushima page

a bit more on the E off Fukushima 5.7 : muzzy
some more maps, 2 days since the 5.7
a wee bit of aftershock concentration around it, but generally the main series carries on and on and on
