Quake Watch 2011

reply to post by radpetey


In 1964, there was a 9.2 earthquake in Alaska. I don't know what part it was in, but that is still massive. It's weird. A few hours ago I was just thinking about The Big One for British Columbia so I type in 'earthquake' in google news search and the info on the Alaska quake comes up. Seems like these big earthquakes are getting closer and closer to BC. If the Big One happens before/during 2012, i expect the 2012 fear to raise to even higher heights.

That is because RSOE are notorious for not updating information. They post it once and that is it, even if it is doubled up.

They also fail to remove quakes that are computer generated errors. Whilst RSOE might be OK for chemical spills, vehicle accidents etc I would not use it for earthquakes under any circumstances.

If you want serious sites (and even they get it wrong) take your pick from here or the sidebar of that page. Yes RSOE is in that list. I am not saying don't use, just don't depend on it.

Okey thanks for the tip

The 7.2 in Alaska could be followed in a month or so by an 8+

But then again it probably won't be.

Edit to say:
This is directly at variance with another prognostication of mine which just goes to show that it is all conjecture and guessing. Does that make me a scientist I wonder?

gday PuterMan...

was just noticing...

both of the "big ones" today were at the exact same depths...62.6kms...

coincidence?

plus: we normally have 4 or 5 E/Qs of MAG 5+ per day,
two of 6+ per week, and one 7+ per month ROUGHLY

TODAY we have had 3 x 5+s, a 6+ AND a 7+...also 3 other 6s this week..

theres a whole lotta shakin goin on !

seeya

reply to post by PuterMan


also: are U calling the 8+ (next month) for ALASKA too??? or somewhere else?

i hear the smart money is still on JAPAN !!!

that E/Q yesterday (the 5.2) was interesting...
= further south than the bulk of the JAP activity...
ie: KYUSHU... + making me think that there is still more activity in store,
+ possibly closer to TOKYO next time...

just thinkin out loud...

Well I would not say I was calling it. Just idle speculation, but yes Alaska. It won't happen!

Depths? I guess it must be coincidence since that is not what you could call a default depth! Maybe the outer layer of the earth is getting ready to peel off at the 62.6 mark. Just kidding!

plus: we normally have 4 or 5 E/Qs of MAG 5+ per day,
two of 6+ per week, and one 7+ per month ROUGHLY

4 or 5 Mag 5 - yes
2 Mag 6 per week? Probably a bit under. There are around 130 to 150 per year.
1 Mag 7 a month? On the low side - getting closer to 2 last year with 21 x 7+

KYUSHU

Always a good bit happening there.

Edit to add:

i hear the smart money is still on JAPAN !!!

Nope, not smart money. Losers that keep the bookies in Rolls Royces! For reasons that I have posted before it won't be Japan. The ONLY possible place is Alaska. Just you wait and see how wrong I am if I am right.

OK, in relation to RSOE as it happens another member asked me a question about the earthquakes that RSOE are showing at Campi Flegri.

Here is the page. Scroll to the end and you will see a list of seismic activity. To all intents and purposes this appears at first glance to be related to Campi Flegri.

That is NOT an unreasonable assumption to make as it is on the Campi Flegri page. Generally I believe that this is the case - the activity posted relates to the area of concern.

BUT - currently at least - the Campi Flegri list is NOT related to Campi Flegri but is world wide, or actually now I have scanned it - Japan!

Here is the list:
Date Time Magnitude Depth
2011-06-23 10:15:58 4.7 35 Km - This is Honshu, Japan
2011-06-22 21:50:53 Mw 6. 40 Km - This is Honshu, Japan and is actually 6.7
2011-06-22 14:29:00 5.5 40 Km - This is Honshu, Japan
2011-06-13 06:50:35 5.0 40 Km - This is also Honshu, Japan
2011-06-13 00:25:28 4.8 20 Km - Yup this is also Honshu, Japan.
2011-06-09 18:15:55 5.0 52 Km - Did you guess this one? Yup Japan
2011-06-08 07:53:46 4.7 30 Km - Just for a change this is Hokkaido - but yup - Japan.
2011-06-07 03:52:31 4.7 32 Km - Bet you did not get this one? Japan, Honshu.
2011-06-06 00:46:47 4.8 40 Km - Boring - Honshu Japan again!
2011-06-01 18:37:06 4.7 70 Km - Maybe this will be different? Nope. Honshu, Japan.

Bythe way Honshu is located just off the coast of Italy. Well it is now according to RSOE!

RSOE may be archivist oriented who keeps automated computer alerts, this case from NOAA PTWC.

It was double listed for a few minutes.





The old NOAA 7.3 and prior to downgrade 7.4 with regional Mw magnitude type.

The day I decide to take a brake from quake watching, and what happens!! One in my own country.

Yup It happens. Unfortunate some sites are not as quick to, or never, upgrade to the latest details.

Double listing happens often as the computer system may interpret a large quake as two due to the massive voltage differences coming in from the instrument. This rarely happens with lower magnitude quakes except where there are transmission line losses which cause 'phantom' earthquakes. Double listing is a similar effect.

I try not to publish any info myself until at least 6 hours after the event when things have settled down.

RSOE may be archivist oriented who keeps automated computer alerts, this case from NOAA PTWC.

I also keep old versions - all of them - but I try not to publish old material!!

Not knocking them, but saying be aware. Actually I am. If they can get the listing once they can also get the update unless they are using RSS feeds? Maybe those don't update? The data I use is the 7 day text file so ANY changes inside the initial 7 day period are captured. NONE of theses sites are gospel! ....and yes it is sloppy computer work!

You can see it on this siesmo from Bud Explorer though(at the top) www.iris.edu...

No use looking for it on SNZO LISS graph, its saturated with Fox Islands 7.2


A wee swarm going on offshore Castlepoint, Wairarapa too Map

well..... looking at today;s list of EQ's we can state that CME's triggers EQ's???????
with other words an cloud of particles has the same effect of an bang with an sledgehammer
