Quake Watch 2011

reply to post by radpetey


No, but they don't always happen immediately after. Generally it seems there are a bunch of mag 4+ that follow, so I guess some will be along shortly perhaps.

Mag 4+ as an example.

reply to post by crazydaisy

Hard to know if it indicates anything. Back on Nov 28, 2008, there was a mag. 5.8 quake off the coast of Nth California (at 40.336 N, 126.981 W) and there were no aftershocks for that one either -- at least, nothing of sufficient size to make it onto the USGS maps. I recall it only because I'd been discussing it with a few members in another thread at the time. Even then, we were puzzled about it but seeing as nothing major followed we just accepted it as an oddity.

To confirm there were no aftershocks we can refer to this page on the U. Of California San Diego website, that gives details about it and also has a map. No aftershocks are shown. (The last update of the page was in January this year, so it's not like they simply posted right after the quake and never checked it again.)

EDIT to add: I meant to include a screenshot of the regional map that I saved from USGS on the evening of Nov 30, two days after the quake. (There is no longer a direct link to this image on the USGS site so I can only assign them credit for it and give a link to the home page for the USGS earthquake site, which is supplied here.)


As you can see, there were no aftershocks in the two days following the quake and I do not recall any even within the following week in that immediate region. In many other cases of quakes around mag 5 or bigger, both in this region and on up into OR and WA, I observed aftershocks within hours and quite often, several of them in the mag 4 down to high-2 range. As Puterman has said and clearly demonstrated, some mag 4 quakes are pretty much the norm after most mag 5-range events. But sometimes, we get an odd one.

I am sure it would be a great field of research to investigate the "why" of such anomalies.

(End of edit.)

So, it could be that for whatever reason, this latest quake is also one of the rather odd shallow ones that show no siginificant aftershock activity. Simply put, while shallow quakes in this range often have aftershocks, not all do. By no means does it have to indicate something major is imminent in the region.

Best regards,

Mike

We can only hope this is an "oddity" as well.
I would not want to see a larger quake
off the Oregon Coast. Perhaps we will
see some aftershocks soon.

This explains much

Dark side perhaps!

Whilst there appears to be no direct correlation I do have the feeling that such a large body - (the Moon

) - should have an effect.

Okay I'm back...
Sorry folks...
Quick question: This is showing up for Gran Canaria.. there are similar things appearing for fuertaventura, and tenerife... Could anyone tell me what would cause it?



There's a big red ring around the 'thing' in question, although even to a pro-Noob like me I can see something weird about that picture without rings of redness...


Edited so you could see this one.. it's from the 12th october, Gran canaria again.. I have absolutely no idea if the shapes being thrown on here are normal or not.. But even I went 'Whooa' at this one..



Please put me in my place if it's a normal thing..

Hmmm..... the 6.1 last night & the 6.7 tonight both in the same time frame.Less than 20 minutes difference.

Check out the helicorders...folkworm.ceri.memphis.edu...

Sorry I don't know how to do a link! Some of them aren't up to date, but check out the ones for the 13 th & 14th. Some in the earlier time zones already changed over! Some are ho hum, but some are really awesome!
If you don't want to look at them all, just check Albuquerque NM, Cathedral Cave MO, Vicksburg MS, Wyandotte Cave IN, Wichita Mountain OK, the second heli, & Waverly TN both. Make sure you scroll all the way to the end to see where most of them started.

Amazing how even two in the same state can be so different. Some patterns that I never saw before. The 6.7?

reply to post by wasobservingquietly


Hi wasobservingquietly, as you say some of those instruments appear to be in need of a couple of aspirin!

Specifically if we take WMOK.US WM the CERI version is very scrambled:


However if we look at the same seismo using Quack Query it looks like this WMOK.US.10.BHZ.2011.287 which is a bit more calming to the old nerves!

In answer yes, any of the big movements are due to the mag 6 quakes which at these distances give the large widely spaced waves you can see on the second plot. (Although those are quite small compared to some)

reply to post by Deplume


Whilst I have no particular idea what it is you can safely say that it is not seismic related for two reasons.

First it is around 10.5Hz and thus a good bit out side earthquake frequencies and it it was volcanic there would be more in between the signal and the low levels. Volcanic tremor and harmonic tremor are fuzzy signals anyway as we have seen.

Second, and the most compelling reason is that it is square and it stops instantly! Earthquakes and volcanoes just don't work like that, and in this case it is not solar/lightening induced because the sun and natural electrical discharge does not do that either. That is a man made signal for 100% certain however I would not venture to suggest a source without being able to listen to it which I cannot.

Edit to add:

Please put me in my place if it's a normal thing..

I hope that we don't 'put people in their place' (well except the odd troll) since this is surely about knowledge and learning - edumacation as Homer would say.




The IU seismo MACI on Tenerife is not showing this signal as far as I can see, in fact it looks boringly normal.

I can only conclude that my brother on Lanarote who is a DJ has his equipment turned way up

As to why no aftershocks of the 5.3/Oregon, well- cause it was a 5.3 and not a 6+?

I seem to recall another quake or two in that mag range there some time ago, with no aftershocks either. Happens even more in Sumatra, with bigger quakes than that. Often we see no aftershocks for 6+'s there. I believe it has to do with the type, magnitude, and orientation of the slippage on the fault. Some are gonna aftershock and others aren't.

On a 5.3 off the Juan De Fuca, I would not expect much in the way of aftershocks. Historical seismicity there does not suggest it is a foreshock- cause heck- they've had a bunch there with no further consequence.

On the other hand, a compounding problem (for us, at least) with that location is there could well be aftershocks- but they are so far away from the usual seismometers on the coast that they are not detected 185 miles into the ocean- and on the west coast where the waves are attenuated well anyway. I don't know to what degree if any they are monitoring some of the Juan De Fuca way out at sea on the ocean bottom like they do in Japan. In other words, if there is no seismo within 100 or more miles of the activity, the smaller aftershock activity may not be detected.

When a fault moves with a seismo station nearby, you can often see the aftershocks in GEE- but they are so small they don't make the USGS lists. That happens a lot, actually, on faults all over. The USGS and local networks are well aware of them though. Along with a few GEE users.

Also in agreement that squiggly looks like telemetry or digitizer error on the Canary Islands spectrograph. Errors are part of the deal with so much equipment in line.

But one thing I love about the IGN is the ability to show spectral displays for frequency content- WITH the corresponding quake directly above it on a webicorder display. Umm, hello USGS? Hint, friggin HINT.

The ability to instantly see frequency distribution is very telling, very fast. We need that USGS. Please?

I have a question. Why is RSOE showing two 6.7 mag EQ in Papa NewGuin? One at 3:42am at a depth of 57 km and one at 3:43 am at a depth of 0km ?? Is this a glitch?

hisz.rsoe.hu...

Can someone explain please?

I'm sorry to ask but can anyone calculate this?If I am in L.A and The time is 10 minutes to 4 pm and I feel the earthquake and the earthquake is triggered in the ocean and tsunami wave hit at 4:29 pm, then What could be the distance and the point in the ocean where the earthquake occurred?San Francisco is struck 4:41 pm!!

reply to post by Jerisa


It always does that. I don't know why but whenever there is a 5.0 or above it usually shows 2 of the same mag. right next to each other.

reply to post by Jerisa
Because they always show 2 independent entry of the event ,for example one from USGS and other one from emsc-csem ,usually electronic submitted by a computer,and so they display the first recording with now depth, there are hundreds of independent recordings from the same event and after many corroborations they get the close to real parameters of the event and not even then,it.s the same with globalincidentmap info from hundreds of networks and is for +5 because those are major events and they could get sued if they give wrong data,a major event could trigger a tsunami....so you understand!!

That Finschhafen, PNG 6.7 didn't lose much S wave energy on its 4678 km, 7 minute, 50 second journey to SNZO ( calc. travel speed 35,831.5km per hour)
Port Moresby Station only 319.8 km away took 44 seconds ( calc. travel speed 26,165.5km per hour) a slow start

LISS SNZO
LISS PMG

I'm not sure whats with that 2nd signal at 4:18ish on SNZO, its not the Russian 6.1, thats at 6:33ish
Also unsure why USGS didn't use SNZO on their phase data, but used URZ, RPZ, ODZ etc.

sources used for calculations;
USGS Phase data
Distance Calculator
Time Calculator
Speed Calculator
I'm really getting to like that Earthquake-Report site , most big quakes are covered in quite good detail, with alternative Network magnitudes, area Historic quakes, Shaking Intensity and Felt Reports where available, plus the biggest plus, its updated regularily, the go to place for info IMO,all on one page
EQR PNG quake report

Edit: I was wondering what WTH was that "HON" magnitude type on the USGS phase data at the top I mean lets make thing more complicated than they already are eh
My guess is that seeing as the magnitude type on the Details page points to NOAA, Pacific Tsunami Warning Center, Honolulu, Hawaii, HON must stand for HONolulu
Something new?
or maybe I just never noticed before?

depends how big it was

because they are useless.
a waste of time IMO
use the main earthquake networks for the real deal
