Quake Watch 2011

Folks you need to be aware that even USGS listings have to be in ex tags and be attributed.

Read back from this post

www.abovetopsecret.com...

This resulted from me being pulled by a mod - as I mentioned - for quoting my own data. Even that has to be tagged with ex.

I would remind you my dear friends that failing to use the ex tags (despite past practise) is against the T & C and is a 3 day post ban first time and total discombooberation the next time. Once you have been discombooberated you will then be discombobulated and be no more to ATS.

I don't want that to happen to any of my friends so just bear in mind this warning please.

Wow have things gone quiet. Can you believe things are have calmed down so quickly? I'm sure before I finish this sentence something will show up. Even Arkansas is quiet. Yellowstone is quiet.

I won't mind if things return to normal. There's been way to much shaking ever since Christchurch. Although fascinated by the squiggly lines and the forces of nature, I can't ever really enjoy watching because you know someone is experiencing the real event. Yes, Japan and Christchurch are on my mind, and the people of Arkansas, but they are not really the ones I'll remember most. I will never forget the giant squiggly line I later found was in Haiti. I didn't need a single news report to know how very bad it was going to be. For you see, I knew how they're buildings were constructed. I knew they were completely unprepared.

so just putting the source at the bottom isn't good enough

ha! I just found that tab up top there, "ex-text", wondered what that was for.

To be honest I think its a bit useless for us Quake Watchers, we like to see the actuall source link as well to go have a closer look.

WOW ... look how quiet the morning of the 11th was

reply to post by harryhaller


Quiet? I am sure that this must be normal, nothing to see here, nothing abnormal, . . . per usual. All is good, beautiful, peachy . . . so-to-speak.


Yeah, so sorry about the sarcasm . . . but just backing the usual crowd that proclaims normalcy . . . or not; I used to be one of them, but alas I am no more!

May I remind you that the quietest two years by far in the noughties were immediately following Banda Aceh in 2004.

I am not saying that will happen again but it was a significant drop in activity for almost two full years.

reply to post by muzzy


No just putting the source at the bottom is apparently not good enough.

As no exceptions can be made to the T&C for any member , the staff request that if you continue to use your database for source material in the future please , follow ATS Policy by listing your sources and using external source tags . The other option is that you make use of other sources .

The USGS to not require that data be enclose in any form of attribution tags. It makes it unusable and often unreadable. As far as these Government organisations are concerned it is sufficient to attribute the data.

Since we are on ATS we have to abide by the rules of the site and this is that ALL external material is enclosed in ex tags and has the correct attribution with links back to the sources where such are available.

No distinction is being made between data and peop0les 'works' which is unfortunate, but there you go, who are we to argue? We just use the site.

A tip by the way. The data listing look stupid when enclosed in ex tags. They return to normality if a smaller font is used. I have found that the size tag set to 2 works fine but needs to be inside the ex tags.

In other words without brackets and with spaces: ex size = 2 ....... / size / ex

Here is the Honshu 6.6 quake this morning with and without size

Both of the following example are source from USGS Latest Earthquakes In The Wolrd 7 day listing

First with size:

I've found it helpful at times to first paste the quote then add the ubb code.
I really wish we had a code for tables, proportional fonts just don't cut it.

reply to post by muzzy


Love the marbles Muzzy! It also shows you how things are quietening down there.

It would be interesting to se that without Honshu as well.

reply to post by Phage


Yes that is what I normally do.

I really wish we had a code for tables, proportional fonts just don't cut it.

100% behind you on that one. Nice tables of earthquake data would be a dream! Even if.......ah wait I had forgotten there is Courier New available - that is not proportional.

3 Aftershocks above Mag 6 today so far in the last 3 Hours

edit on 22-3-2011 by Shenon because: (no reason given)

The aftershocks seem to be increasing in magnitude as time goes by. Is this normal?

So is it my imagination or has Japan just had 3 6+ quakes in quick succession? Source: my computer monitor shaking.

Do I have to do ex text if it's from an email notification?

2 Posts above yours. PuterMan? Are those Aftershocks or not?


reply to post by UKTruth


I´m no expert,but i don´t think those are Aftershocks...maybe those are from the Pacific Plate releasing some build up stress...

Theoretically I believe, the magnitude of aftershocks is supposed to reduce temporally and perhaps hang around at a smaller constant and become fewer.
What worries me about Japan is that the magnitudes of the aftershocks reduce and then increase, reduce and increase....when is it going to settle down? How much more damage will Japan have to suffer?

@Shenon: yes I know it was a couple of posts above mine, just trying to get out of the quoting (tired and feeling lazy) and it was more a display of shock than a question.

reply to post by zenius


Now i get what you mean about the ex-tag thing...gosh,my Brain is too slow without enough Coffee

Anyway,the Amount of Mag 6+ Aftershocks did decrease since the Main Mag 9...until now that is. But the first 6.6 today was almost directly on the Fault Line,the 6.4 and 6.6 after that is somehow on Line with the Fault torwards the west. Lets hope there isn´t going to be another 6 + further South of those....

Where are those Quake Nerds when you need them

pm is around here somewhere.

I'd be more worried if the quakes got worse further south. I think the Phillipine plate is starting to feel it and Indonesia through to Tonga I think might be reacting also.

From personal experience (the 7.1 in NZ, then the 6.1 in NZ) this doesn't look too unusual a pattern of aftershocks. We had (and still have) periods of decreasing frequency and mag, only to be bitten on the bum by a biggie a week or so later... 5 weeks after the 7.1 we had decreasing down to high 3's and 4 when bam, several 5's in the next weeks... I think the sheer size of their aftershocks, resulting from such a huge 9.0 mainshock, is what is causing the wow factor.
