Thanks, PuterMan. It just looks like quite a few over 5.0 in a short four hours in Alaska and other areas of the Pacific rim this morning (currently 11:52 here)

This is the list for 5.0+ in Alaska and Japan over the past 7 days


Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2011-05-05 18:36:13, 35.607, 142.046, 5.1, 1.9, Off N. Coast Of Honshu. Japan

2011-05-05 16:57:38, 55.136, -160.616, 5.9, 46.9, Alaska Peninsula
2011-05-05 14:58:21, 38.173, 144.039, 6.1, 24.2, Off N. Coast Of Honshu. Japan
2011-05-05 14:13:01, 55.118, -160.568, 5.8, 39.1, Alaska Peninsula
2011-05-04 08:23:53, 37.051, 143.260, 5.5, 35.5, Off N. Coast Of Honshu. Japan
2011-05-04 08:23:48, 37.120, 143.380, 5.3, 2.0, Off N. Coast Of Honshu Japan
2011-05-04 05:41:40, 40.847, 141.233, 5.0, 35.7, Nr. N. Coast Of Honshu. Japan
2011-05-02 21:25:49, 40.085, 142.597, 5.1, 30.0, Nr. N. Coast Of Honshu. Japan
2011-05-02 21:25:48, 40.190, 142.500, 5.2, 24.0, Nr. N. Coast Of Honshu Japan
2011-04-30 05:06:36, 36.787, 141.092, 5.2, 40.3, Nr. N. Coast Of Honshu. Japan
2011-04-29 22:19:32, 38.914, 141.932, 5.3, 51.3, Nr. N. Coast Of Honshu. Japan
2011-04-28 09:27:48, 37.492, 141.652, 5.8, 48.9, Nr. N. Coast Of Honshu. Japan




As you can see they are mainly all Japan, and as far as Japan goes it has been relatively quiet so not unexpected.

That numbers list was a new venture - I had not done it by month before. Looks like a good way of spotting activity increases. Normally I do a daily cumulative which give a straight line if nothing is happening. I shall have a play with this.

No-one should be at all surprised at Japan still getting 6+ aftershocks, this sequence could go on for years.

In reality they're still due a much larger one as usually they expect an aftershock to occur of around 1mag down from the mainshock.

The question is are "they" right? I think that is a bit of an old wives tale despite the fact that I quote it. I keep on meaning to get back to checking this out, but it did not happen after Chile


Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2010-07-14 08:32:22, -38.002, -73.281, 6.5, 28.4, Bio-Bio. Chile
2010-03-16 02:21:58, -36.124, -73.146, 6.7, 18.0, Offshore Bio-Bio. Chile
2010-03-11 14:55:27, -34.281, -71.837, 6.7, 18.0, O' Higgins. Chile
2010-03-11 14:39:44, -34.259, -71.928, 6.9, 11.0, O' Higgins. Chile
2010-03-05 11:47:10, -36.512, -73.116, 6.6, 35.0, Offshore Bio-Bio. Chile
2010-02-27 06:34:14, -35.908, -72.732, 8.8, 35.0, Offshore Maule. Chile




6.9 was the largest during the whole year except for the 8.8

We shall see but it is my guess that we will see nothing higher than another 7.2 in the Honshu area and I believe we won't even see that. Maybe a few more mag 6.0 to 6.8 and that is it.

Edit: Just dug up the Chile 1960 data

As you can see there was an 8.2 BEFORE the 9.5 but nothing bigger that a 7.1 in the next year until the 7.5 in 1962.
End Edit

And another edit to blow away the theory

Oops, Alaska (1964) ain't playin ball either. (I should say that I am ONLY looking a 8.5+. It possibly could apply to lower magnitude main shocks.)

End Edit

I further prognosticate that there is not a cat in hells chance of an 8.0+ in the US anywhere in the next 10 months.

All this is pure supposition and should be treated with contempt and suspicion, or even derision,
but bet I am right

Hi all, I just wanted to say hello. I just signed up for ATS, I like to follow earthquakes and anything along those lines and have decided to see if ATS can offer me more subject matter along the lines I am interested in then the other site I have been trying to discuss these matters on.

So that's it Hello all!!! I am looking forward to having meaningful & insightful conversations about earth related topics with the contributors in this thread and in the fragile earth board.

Please don't take this as a personal vendetta against you MoorfNZ. I said the same as you but something niggled in the back of the mind when I started doing the figures from 1930 onwards.

Looking at Banda Aceh next.

??? Nothing further until 2000 bigger than 6.0

Summarising all that


You could say that the rules possibly applies in Sumatra/Indonesia.

Japan 1923 was too small to be in the list but it has quakes close to the main shock but we are talking 7 and under.

For me, for SUPER quakes, the rules do not apply except in Indonesia.

cat in hells chance


LOL That's a new one to me my friend - never heard that one before.

Nice data on the the "aftershocks" - suprising actually. Almost appears that the Foreshocks are larger leading upt to the main quake. (Sorry Robin for using all those terms I know you hate :-) )

I thought you might.

There were another 3 yesterday (Incl 2 x mag3) and 1 today.
I've put yesterdays on the static map.

Was looking at Chris Crowes Canterbury Quake Live search page quake.crowe.co.nz...

you can move the marker over to Black Hill and select the number of days, km area etc and see much the same thing.

Looks like he works in NZST.
I find that too confusing, after working with UTC for so long

Nice work


I wonder if it applies to Mag 7's ?

Seems to here in NZ

Dusky Sound 2009
Darfield 2010

Just 2 recent ones off the top of my head that had a 6 aftershock

I believe it does apply to the lower levels of magnitude without much doubt, which is no doubt where the theory has arisen.

It is interesting that it seems not to apply to the super-quakes.

The North California JDF plate area is not showing any increase in activity, indeed if anything it is tailing off ever so slightly.



Much the same could be said about the magnitudes which are trending downwards since the Jan 2010 biggish one (not shown)






also this area near me, we havent seen this much activity in a while here


I can't say I have looked at this recently, but I did a study on it last year some time. (Download it here which no one has looked at yet. You can even get a copy of the data I used.)


The purpose of this study was to determine whether the current events occurring in the area of Clear Water are part of a larger pattern and might be the pre-cursor to a larger event.
Data for the study was taken solely from the ANSS data catalog.
Data was requested from 1st January, 1970 to the current date (August 13th 2010) using the following parameters.
* catalog=ANSS
* start_time=1970/01/01,00:00:00
* end_time=2010/08/13,17:41:42
* minimum_magnitude=0
* maximum_magnitude=10
* event_type=E
* delta=0 km to 25 km from (38.8,-122.8)


The opening paragraph of the document so as you can see it is about the area you mention. It is packed with figures and graphs. The long and short of it the reason for the quakes is this:

LOL That's a new one to me my friend - never heard that one before.


A phrase I have known all my life. Particularly British, even though i did find one site trying to claim it was American

The Free Dictionary

It has been said this phrase is an abbreviation of the phrase,"No more chance than a cat in hell without claws". This refers to the hopeless situation of being without weapons (claws) when needed. I am not so sure about that.

You can understand the "Snowball in hell's chance" but that is not used here very much.

Just to keep this on topic


Almost appears that the Foreshocks are larger leading up to the main quake.


Yes I noticed that. I shall still be taking a fuller look at this later on in the year.

As always, Puterman, thorough work and explanation!
Thanks!

Wonder where/how the rule of thumb originated - it was certainly bounded about by geo's here after the 7.1

have been following the med area as my sister lives in Crete and noticed the activity around Etna, is this a sign that it is gearing up to erupt?
