Quake Watch 2012

reply to post by alfa1


I am assuming you built one of those Shackleford-Gunderson seismometers then? Sounds very interesting. The software I knew about but that particular seismometer I did not.

I got as far as...........

A two-inch-square plate will have a capacity of 76 picofarads and so will require an inductor of approximately 13.4 microhenries to resonate at five megahertz .

Yup, OK I get it, NOT! I guess the instructions are not written to help nit-wits build one of these then!


ETA: I quite like the look of this one for the 'mechanical' side of it: Slinky Mk VIII Seismometer. You can download a PDF manual from that page as well.

I pose this question too one of our resident quake Yoda's....

Why are there so few aftershocks from the Indonesian quake??

reply to post by PuterMan

OK if it was reduced to 7.2Mw to 7.0Mw later there isn't much I can do except alter the popup tag on that one. Messes up the 2010 graph too.
I'll probably leave it for another year or so so they can decide for sure.

I wasn't using the GFZ conversion table anyway, just comparing 2 quakes in the same spot that had different Mw results of 6.9ML/7.0Mw and 7.0ML/6.7Mw
unfortunately UGS didn't give an ML themselves so had to use BKG, so its not a direct comparison I guess.

depends where you look

BKG only show 5+ unless they were felt
UGS only 4.5+
GFZ have 3

Seems like a small amount of afters for a quake of that mag.....and not to deep to boot!

Thanks for hollerin' back at me!

5.0 Parrita Costa Rica
6km (4mi) NNE of Parrita, Costa Rica
19km (12mi) SSW of Tejar, Costa Rica
27km (17mi) S of San Rafael Abajo, Costa Rica
38km (24mi) SW of Aserri, Costa Rica
45km (28mi) SSW of San Jose, Costa Rica

Something tells me this area is not through shaking after it's big Quake last month. My parents and family felt this one too.

With Geonets SeisComP3 settling in there is no database for New Zealand from Sept 1st, they don't expect it to be back until 2013.
Its OK though, with the aid of Mr. Puterman and his QVS program we are able to access the data that IS being gathered and process it.
I've managed to keep NZ Earthquakes blog rolling along, once I got the hang of gathering the data.
As far as database, the best way I see of presenting it, and finally get something going on the Energy Released side of things, which after all is more important than counting the number of quakes, is to map that too.
Here is what I have done for September 2012, I'll go back in time too, to create an archive for comparison purposes.
If you look at the numbers ER you can see the South of the Kermys is way ahead of elsewhere and Waikato/Bay of Plenty second, Taranaki and the Volcanic Plateau about neck and neck with Canterbury


Thats just one map of 21 on the page so far, each area shown on that map is broken down and has all the quakes plotted.
New Zealand GL Seismic Regions Energy Released Summaries, Archive for ‘Sept2012’

I tried to get the static maps and the interactive maps to match up side by side, but this Wordpress theme is based on columns so although it looks great on MY laptop it might not be completely lined up side by side if you have a big screen. Also there are 2154 icons (1077 quakes shown twice) to load on all the maps on the Sept category page alone so patience is needed. Dialup? - forget it, it will probably timeout.

ETA: if you want to get to know the GL Regions, click on the "about" tab at the top or just to get a handle on the region numbers click on the header to go to the "pinned" key map that comes up every time you open the blog



ETA@: Oh Sept started on the 5th BTW, don't ask me why, I just noticed that

I went back to Sept 1st and added 151 quakes to Sept.
New TTNT Map below.
I also changed some maps to satellite view, those where the quakes were predominately offshore, and I added two more GL region maps I had missed out before, Kermadec Islands and Northwest of New Zealand

Waikato-Bay of Plenty way ahead now, I knew there was a Mag 5 in there somewhere
Total for Sept of 5056.912TTNT now closely matches the graph on my other NZ blog , the difference will be a few minor quakes added during Sept, I usually try and post the daily graphs within 3 days of the day, so anything added to the "database" doesn't show up in the graphs either.
5056.912TTNT equal to a single Mag 5.685
so with the West of Rotorua 5.5 at 2853.7TTNT
that leaves 2226.821 for all the other quakes combined which equals a Mag 5.45
or 3 x Mag 5.128's
the combinations are limitless ....................................

But you can see why some of us here pick over the decimal point differences when a decent sized quake happens, the differences between say a 6.1 and a 6.6 are huge.

Two small quakes at Yellowstone. Given it's location, I'd thought I'd say something.

Edit: Make that a 3rd as I typed this.

My count is now 5. Some in Idaho others Wyoming. I haven't seen a swarm like this in a while. Looking for large quake in Japan or Russia.

I have 6 including the latest , a 3.0.

Definitely watching this one tonight...

reply to post by ujustneverknow


Only 90 miles away I wonder if it will be quick or take a while if it decides to go. My thoughts have always been that it would not go or at least go completely, But that big bubble in the Yellowstone lake could burst at any time. Seems that a lot of magma is flowing but I believe that the chamber is in Montana but close to Idaho.

I thought there would be some smaller ones too, but so far none!

Here are the Yellowstone seismos:

It might have something to do with this one:

Granted, it's not that big, but you never know.
Unless that one & the first smaller one were foreshocks!

Something tells me it's not going to just stop at six little quick trembles.

Just for kicks I;m watching the Old Faithful live cam , nothing yet but a funny guy dancing around and being a ham!

Crossing my fingers this is just a series of hiccups !

reply to post by prophetboy12


I don't usually jumps on these wagons because it can be a bumpy ride but....... Japan has been really quite.

Crossing my fingers hoping another quake hits and scares the pants off those 2 guys on cam right now.

Hey you guys ^^^^^^
This little swarm is pretty normal for Yellowstone...go check out the dedicated Yellowstone MEGA thread
