Over FIFTY earthquakes in the last several hours in Alaska and still counting

Haarp is in Alaska.
Could it be a side effect of outputting all that power around the world?

drx,
I'm not sure what you are saying about muslim countries. these quakes arent affecting them. Imo I'd say it's just something the earth is doing. not manmade. and I would say 1 of 2 things either they will lead to something major( which I am leaning towards), or they will lead to nothing at all. Either way, it is still very interesting all the same.

According to him nothing special is happening.

No, nothing major is happening...that's just the regular occurrence for Alaska. Alaska gets a lot of earthquakes. The southern border of the state, the whole length from
Southeast Alaska out the Aleutian chain sits on the boundary of the North American plate and the Pacific plate, most of that length with a subduction zone type boundary.
Besides that plate boundary, there are some major fault systems in the interior of the state too (Castle Mtn., Denali and Tintina to name a few). There are many active
volcanoes here, and they can cause seismic activity. Alaska is also a large state, 1/5th the size of the lower 48 states combined. Add up all these factors and the
earthquakes can pile up pretty quick.

This is their reaction I recieved a few days ago..

Here's the link to the page showing the last 30 days of earthquakes worldwide. It only shows temblors of magnitude 4+ though, but once you take out the smaller quakes/aftershocks, you get an idea of why seismologists and geologists aren't terribly concerned over the Alaskan activity.

IRIS - 30 days of quakes

There was one blurb on internet free press posted by "intellpuke" about the quakes and that's really all I could find in print.

I have yet to hear back from the "local" news agency, but I'll post if and when I do.

I doubt it's any kind of cover up or "man made" issue...it's likely just more common than most realize (I know I really didn't know that Alaska is frequently shaking) It is a bit creepy though, not knowing if it's a prelude to larger quakes or if it's just "minor" slipage relieving pressure.

Living in a quake zone sort of makes you take notice of these things

The South Bay quake made the news... heavily populated area=newsworthy.

IRIS has some interesting educational info as well. A pretty good read

I'll be away for the weekend but I'll try to post any reply from the news folks - cheers all and keep up the good work

A response from one of the five people I emailed at the EQ HQ in Alaska.

Hi Daryl,

I am forwarding your inquiry on to someone at the Alaska Volcano Observatory. I personally do not have access to the data they use to be able to sufficiently answer your question. If you do not hear from them please feel free to contact me again and I will do everything I can to expedite your request for information.

Regards,

Edward P. Klimasauskas

U.S. Geological Survey

So he is referring me to the Volcano guys now...

Just got a 2nd response from another of the Geologists in Alaska saying the same thing, talk to the Volcano guys.

I think you have to expect to be refered to other people, espeically when you send emails to everyone on a list of general geologists.

Klimasaukas studies:

alaska.usgs.gov...
Public affairs and policy, societal impacts/mitigation of natural hazards, volcanic hazards mapping, trace element and isotope geochemistry, volcanogenic ore deposits and metalogenesis, geographic information systems, and remote sensing.

his papers are of the likes of:

Major- and Trace-Element Concentrations in Rock Samples
Zinc Mineral Commodity Profile
Reconnaissance bedrock geologic map for the northern Alaska Peninsula area
and
Mineral Commodity of the Month: Cadmium

When I contacted people regarding this, I emailed their information assistant, as she'd be the one to, possibly, distribute information.

If you want peopel who are in the know and what their opinion is of this situation, you'll be looking for people that study tectonics from that list.

My guess is that you will get a discussion where the term 'supercriticality' comes up. But you should definitelyt contact an earthquake specialist.

Is it the Denali fault? The one that triggered the activity in Yellowstone in 2002? There is a supervolcano under Yellowstone, the caldera is moving toward the surface daily.

It's already quiet for like 5 hours in Alaska, do you think it means something?

there was a 5.7 in japan, and 5.3 at sea of okhotsk

Got a reply from the Volcano people

Daryl,

The Rat Islands earthquakes are not volcanicogenic. The Alaska Earthquake Information Center webpage about them that may answer some of your questions.
www.aeic.alaska.edu...

Not volcanic and telling me to email more EQ people at Alaska (if anyone wants to email this slew of people feel free, I will not have time to post any replies tonight or for the rest of the weekend.

And a reply from another of the geologists.

Hi Daryl:

I was forwarded your good questions about the interesting recent earthquakes in the Rat Islands. What we are seeing is an aftershock sequence, broadly typical of moderate sized tectonic earthquakes worldwide. Aftershocks can be thought of as the crust continuing to adjust after the main shock and changing of the stress field along the earthquake rupture. This part of the Aleutian subduction zone is a very active, and it is a zone where perpendicular subduction (head on) is transitioning strongly to oblique subduction (at an angle) so earthquake mechanisms become quite complex.

Volcanoes in the region are not showing signs of increased unrest following these events. We maintain good networks on most of the volcanoes nearby the epicenter of the 14 June event and the aftershocks, and all are considered 'normal'. The seismic records at each volcano, however, look extra 'busy' because of the continuing aftershocks. In general, earthquakes of this size are not large enough to prompt volcanic activity: although I will not say it is impossible!

So according to Christina Neal [[email protected]] we are not only seeing after shocks from the 6.4 Alaska had but also from other quakes world wide. This is very interesting. The first question that comes to mind is why have we not seen an extreme amount of after shocks like this before for the local quakes or the world wide quakes?

And yet another reply from another of the geologists I emailed

Undoubtedly, many of the recent Rat Island earthquakes are aftershocks to the M6.4 event which occurred June 13. That quake might have also triggered an earthquake "swarm" or cluster event, possibly triggered by magma movement or accelerated fault creep.

So the general consensus is that they are after shocks but again the question comes to mind is why so many and why have we not seen so many before?

Either you are I is misunderstanding what she is saying. She is saying that they are 'normal' aftershocks, typical of any moderately sized earthquake on the planet.

but again the question comes to mind is why so many and why have we not seen so many before?

According to Baline91555, swarms of aftershocks are normal in the region.

Thanks...I'll be checking there often as well.

Ptolomeo - It would be interesting to see if anyone else here on ATS has taken notice of the brightness of the sun. Seeing there are so many people that visit here from around the world. Possibly a new thread can be created to gather everyones opinion on why it may be looking this way. Maybe there are others here that have been needing to wear sunglasses also because of it.


God Bless

oops...double post.

Cool finding Dk1, good work mate, interesting indeed

Since these events are so common in this area I check various reporting sites regularly. The sites I’m referring to are available in links all throughout this thread.

The number in a day may be unusual but nothing about these events seems to be. If you have looked at the historical data you will see how active that area is. If these were unusual events it would be front page news up here. That does not mean that something extraordinary can or will not happen here at any time. Of course that part of the island chain is so far from here its only local interest is in that it is in Alaska.

The cloud of the 60’s quake is still hanging over many peoples heads here and we are extra sensitive to reports. I’ve only lived here a few years. When the subject of the big quake comes up those that were here turn pale and you can see the fear on their faces. The media here is very aware of the interest and keeps us well informed. They have an open relationship with those that study these events. This has gotten very little attention other than a mention of the quakes.

What would interest me the most is the impact of these quakes on the opposing plate. Although I doubt these quakes were large enough individually to have an impact but what about them collectively. This business about them in some way being connected to the Yellowstone Caldera, in my humble opinion, is just so much garbage. It’s a result of aggressive marketing of that disaster film about Yellowstone. It seems that scaring people is quite profitable.

Stand up. Wave your arms a few times. You have just created more ELF than HAARP.

You will find any answers here. I understand the phony info and the accusations got so bad that Consumer Reports actually came up and reviewed the site for safety.
