Quake Watch 2017

FYI.

Had a 4.6 M here in AK, Jan. 26, 5:26 AM (local) located 76 miles (122 km) west of Talkeetna.

Felt it hear in Anchorage 100 miles (160 km) south.

What is strange is we ha a sizable one hit (7.1 M) almost a year to the day! That one hit 1/24/16.

I mostly slept through it this morning!

Thanks for posting all your work muzzy.

As far as me... Real life has been getting in the way of me sitting down at the computer and absorbing anything.

But, just taking a quick peek, I know I have questions. Especially about the tsunami maps.

And... Well... I have been looking into the Hows of determining whether a person is mentally stable. LOL!!!

a reply to: crappiekat

Well let me know when you find out the "Hows of determining whether a person is mentally stable", there are a few people I know (not on ATS) that I have my doubts about

a reply to: muzzy

Well, just keep paying attention.

I don't think you and I are the only one's asking that question.

LOL!!!

All kidding aside. I really worry about what kind of information regarding geological news will be available to us.

Are you referring to this type of stuff?
www.theguardian.com...

In his first week, Trump also reportedly banned numerous federal agencies from “providing updates on social media or to reporters” with a de facto gag order that sparked widespread concern about censorship and government transparency.

The Department of the Interior’s social media privileges were also briefly suspended after the NPS retweet, which the agency later deleted before issuing a short apology

and
www.theguardian.com...
you think USGS might be told to stop publishing earthquake data?

I have yet to read anything regarding his stance on Fracking but no doubt based on his Climate Change denial then Fracking doesnt cause earthquakes therefore carry on boys drill and inject away

4.2 Geyers, Cali 1.62 miles

earthquake.usgs.gov...-info


I was thinking about fracking/minning.

I e-mailed John Vidale to ask him if he had heard of any attempts to quiet anyone in his area.

Hoping he will pop in here.


Received a quick reply from John.

"No issues for PNS so far. Government developments are a little more exciting than we like, However"

a reply to: crappiekat

Downgraded to 3.9.
I have a look at The Geysers occasionally and you can almost follow which sites are injecting at any given time. A few years back I made a KMZ file of the stations and when matches with a set of earthquake events you could say "hmm they restarted site xyz this week"
I find the Geysers interesting because we have the same system running here at Kawerau, been going since the 1970's, no harm done that has been reported.

If the Trump govt starts to stymie geological agencies openness it could lead to staff being frightned to speak up if something looks dangerous, and end up like Italy in 2009 L'Aquilla where they had warning but did nothing,
thinking Oklakoma, SaltonSea, Yellowstone or Cascadia in particular
but don't worry there are people outside the US keeping an eye on, who can give the heads up.

Couple of new graphs on the Culverden-Cook 7.8 page, to celebrate 75 days since the quake.
nzeq2017.blogspot.co.nz...
Count Graphs, along the lines of the NZ Monthly graphs I used to do.
Reason I did them is I seen the numbers going down steadily over the last 2 weeks to between 40-60/day on the data lists, but words and numbers don't really show the trend.


The 2nd graph is the two areas split by numbers of quakes per day, I thought Cook Strait was slightly ahead on a daily count prior to making the graph, but it looks like Marl-Canterbury is ahead most days, the difference I think is the Cook ones are more concentrated in a smaller area compared to Marl-Cant, so it looks like more on the NZ Maps.
It looks fairly normal deterioration for a big quake, but it does seem to be slowing (events further apart now) quite quickly for a 7.8.
FWIW everyone I talk to around town about the quake says the same "it ain't over yet" A lot of people think there is another M6 in it yet, although Geonet say a less than 25% chance in the next month, but 77% in the next year.

Ditto re posting.

Simple test. Do they believe in conspiracy theories and sites like ATS? Yes they are normal, No they are mentally unstable and being fed by the MSM. I had occasion to watch an RTE News broadcast a couple of days ago and was perturbed by the avalanche of total spurious rubbish being spouted.

Back on topic the USGS have just upgraded a quake to M6
Upgraded quake us10007s20|2017-01-08T23:47:14.390Z|74.3918|-92.4041|6|31|Queen Elizabeth Islands. Canada (678)

and also a few says ago

bumped to 6.3

Nothing to do with Geology, just shutting the Snowflakes up and preventing them leaking 'fake news' about climate change. I do not believe he is wanting to stop 'real' earthquake news being disseminated.

Anybody here keeping an eye on Iceland?

I noticed today 2 big EQ on the MA-ridge running through Iceland, 4.6 and 4.7 mag and 2 days ago there was a 4.3 inside Katla volcano.
www.emsc-csem.org...

Here is an announcement from Science council of the Civil protection agency in Iceland from yestertday;

Earthquake activity in Katla has been unusually high since August 2016, with three earthquakes larger than magnitude 4,0 and many more earthquakes with magnitude 3,0. Earthquake activity is shallow and spread around the caldera. No harmonic tremor has been detected following this earthquake activity. Following this increase in activity small increase in geothermal heat has been observed...

www.jonfr.com...

There is news an eruption of Katla is "right behind the corner"
icelandmonitor.mbl.is...

Anyone has more info on this or following the situation a bit closer? Thx

Hi!

Saw the 4.6 & 4.7 on the fault line south of Iceland,
and then a 4.7 on the fault line north of Iceland.
Is pressure on the fault line affecting Katla,
or is Katla affecting the fault line?
Or just a coincidence?

WOQ

The trifecta is back, with multiples in each place this time.
Peru/Chile, New Guinea, Japan.

Something in the pipeline?
See if it holds true this time.

WOQ

a reply to: wasobservingquietly

I don't think a volcano can effect a fault line that far away.
No chicken/egg issue on this one, the 2 sea based quakes would be tectonic spreading.
Katla the result of the same.
The are not subduction volcanos like Chile, NZ, Japan, Indonesia, Aleutian Is etc, these are like Hawaii and Ethiopia (hotspot/spreading ridge or rift)

a reply to: muzzy

What about a big boom like Krakatoa?
Too many apocalyptic movies & novels! Lol!
Feeling cheeky,
there has to be one in the works!

WOQ

a reply to: wasobservingquietly

Even Krakatoa didn't cause any Faults to fail (the 1800's eruption), and was caused by Indo-Australian Plate subducting the Asian Plate.
It would create tsunamis though.
Speaking of tsunamis
I did an animation of one, Santa Cruz Is 20/5/2015 (further to post www.abovetopsecret.com...)
the frame delay is 45 cs. (centiseconds, or 1/100th of seconds)
I could have made it closer in but the size of the file would be quite big, as it is the size is 223mb or 1/4MB.
Also could zoom in to San Cristobal Is a couple of levels and see the arrivals there a bit better, as its appears that there were several waves time wise, based on the animation. I might just do that now, just to see if I am right.


this would probably work better if there was a controller to stop the animation or adjust the speed, but that means converting to a video and using utube.


Later;
I slowed this one down to 90cs between images
Yeah you can see the waves came in at Namuga on the South East point of San Cristobal twice, 00:28 on the north side, 00:30 on the south side then again 00:34-00:38 on the south side.


Relevance?
I'm sure the San Cristobal locals would be interested, but they probably don't have an internet connection to see this.
May be of some worth to authorities in other locations around the globe to prepare for tsunamis, use as models, but it would need earthquakes to occur is the same places over and over again, as I'm sure every earthquake/tsunami is different (multiple animations of Japans tsunamis will show if this is true of not)
I'm sure the authorities there already do this themselves, and what I am doing in nothing new or amazing.

maybe I should a Tsunami Watch topic on ATS where I can post my animations (and others can put up the (usually wrong) warnings from PTWC.

but these are historical, I'm just experimenting, testing on you quakewatchers to see if it is of interest.

Here is another one I have done
6.8-12.05.2015 Near East Coast Of Honshu
25.7km off the Coast of Honshu, Japan


What this shows me is;
it took 12 minutes for the first wave to hit shore (travelling at roughly 38.2 metres per second according to my calculations)
the tsunami went West South South. Although with no location readings to the East it could have as well gone that way as well, but at least we know it didn't go North.
it must have gained momentum going south, as the wave height there at Ishinomaki was double (green icons), although a lot could depend on the shape of the seafloor leding into Samenoura Bay.
Questions;
there are a lot of bays along this coast, why did this one in particular have a higher reading?
did those islands to the NE cause a funneling effect?

And don't forget that even though these ones are small height, the quakes are also quite small, and that behind those 0.1, 0.2 to 0.5 metre head waves there are gazillions of tons of sea water coming at the shore, not just the curly wavy bit.

Haven't seen one there for a while

GFZ had another ghost quake on West of the Emperor Ridge (North Pacific Ocean) this morning a 6.1, I see it has been removed again.

a reply to: muzzy

You do awesome work Muzzy!

Edit; What is a ghost quake?

a reply to: tikbalang

A Ghost quake is one that wasn't really there, or was there, then disappeared
my name for such anyway
