Yeah its a great find, way better than the old New Caledonia site which I was unable to find.

These guys are quick

Too early to tell how reliable they are though, this one is in an area that doesn't usually have earhquakes

the style of their event maps is the same as Geofon, I wonder if they are helping them out, like they are helping Geonet set up this Geonet Rapid thingy

*ETA; Those quakes probably won't show up on USGS, being selective about which quakes they post up that are 4.5+
I'll keep an eye on the Geofon and Geonet sites later today and see if can confirm those two quakes

wow I just found their Alert Archives, they even do Antarctic

there are 72 quakes listed for the 17th UTC with 6hours to go

This site is the find of the year (for me anyway)

reply to post by muzzy

Hmmmm

seisan.ird.nc...

3.7 ML of 239 kmsNW of New Plymouth

not usually

but hey I'm open minded
they used Geonets stations, so it should show on Geonet data download this evening if its for real

ETA; if nothing else this site may help me to find those "mystery quakes" on LISS SNZO that are never identifed by USGS, Geonet or Geofon

followup to post by muzzy


Hey thanks for waiting ................29 hours no posts

I had to work yesterday so only got around to this this morning.
I've created an interactive map of the data on that last page I linked to from the New Caledonia Seismological Network (or the IRD for short, how they get IRD from that I have no clue, French I guess).
I've compared what they had with Geofon, Geonet, GeoAus, USGS, EMSC and RAS data for the 17th Feb 2012.
Some of the Vanuatu quakes have a match, some of the New Zealand ones do, and then there are many in weird places that don't usually have quakes.
Like Australia had 3 x Mag 5's, so that must be an error, because there is no doubt about it, if there was ONE Mag 5 anywhere in Australia you would hear about it, let alone 3 of them
And some out to the SE of the South Island of NZ, not impossible, but you would think Geonet would have got those.
I also think the mid Tasman Sea ones are errors too, the Chathams not so sure.
The ones that may be correct but we have no confirmation are the South of Australia one, the Antarctica one and the Society Islands one ( Tahiti)

heres the map anyway, I'll leave it up to you all to decide if they are for real or what.

the icon markers are coded as follows;
blank = not confirmed
cm= confirmed match
pm= possible match, time is right but location is off a bit
lm= likely match, either time or location is a bit off but its in the ballpark
usual colors
green=mag 2
grey=mag 3
yellow=mag 4
orange=mag 5

just a note to add on those links on the Archive Alerts, sometimes the text does not match up with the page it actually opens to, as far as location goes. This could be a fully automated service.
I also notice if you go back a few days some of the pages open as page not found, perhaps been checked by a scientist and found to be wrong and hense been deleted.

I'm not going to dismiss the site and put it in the same category as RSOE just yet, it did come out with the Masterton 4.2 quake a full 40 minutes before "trusty" Geonet had anything at all


oh yeah BTW, click on the icon markers for the details

reply to post by muzzy


Odd, can it really have been 29 hours while we waited with bated breath for your analysis? It seems like only yesterday.

I guess with their web data collector not working they are probably a bit of a write off, but we will wait and see.

reply to post by muzzy


Muzzy, when you brought that site to our attention here, I thought that's reall but like you I started noticing incorrect links, OZ 3 x 5's that just didn't add up, as we would have heard about them for sure.

Shame as we know that most of the monitoring sites we follow, don't always do a good job of covering our Southern region.

Things also seem a bit 'quiet' since the excitement around Cali' quakes...lull before the STORM?

Hey TA!

You mentioned on another thread the the NMSZ has been rumbling of late....

Could you pipe in when you get a chance and let us know exactly what is going on, as there are quite a few of regulars that live in close proximity to that nasty little beast.

I am in Memphis, Tn. and am generally always paranoid about this thing unleashing it's fury

Hey you quake nerds! jk

A friend sent me this pretty cool youtube vid on all the quakes for 2011.

Maybe you have seen maybe you have not,but I thought I would share it with you.

2/10/2012 -- MUST SEE ! 2011 earthquakes WORLDWIDE plotted and animated (with sound intensity) !

Earthquake in the world This video is the representation on the map, the distribution of the earthquake that occurred in the world. We refer to the documentation (USGS / NEIC) has announced Earthquake Information Center / U.S. Geological Survey. Summarizes the earthquake of magnitude 4.5 or more. Earthquake show is more than M4.5 USGS / NEIC has announced. Unpublished earthquake are not included under earthquake M4.5, is USGS / NEIC. A source of information was used in the following pages of the USGS.

That is,if it's ok with you,puterman.

reply to post by kdog1982


quite well done I like the markers, how they show both the magnitude and the depth in one go, by using the clock hands idea, too bad you can't really see them on the vid when they are going on and off so fast.

reply to post by kdog1982

That is,if it's ok with you,puterman.

Eh? Why would you be needing my approval? Apart from anything else the thread belongs to ATS and the subject matter is on topic. I have seen the video before and yes it is quite good. It states the facts and is not about conjecture of prediction or doom. You can't argue with facts!

It is a good look at what happened in 2011 in isolation, but of course you cannot look at earthquakes in isolation, other than that it is excellent.


Oh and just to add - it was posted in the future as well? Wicked!! One has to assume that was 10 Feb 2012 and not 02 Oct 2012.

Took me a while to find this decent sized wiggle, I was looking for a 5+, nothing on USGS, EMSC, RAS or Geonet

Found it on Geofon, its Macquarie Island

Interesting size on the graph, bigger than the 5.3 @ Vanuatu on the 17th here

reply to post by muzzy


So it is a 4.7, over the magnitude for collection by both USGS and EMSC. The Caledonia report 39 phases (arrivals), so if they have them and Geofon have them why don't the others?

Did you have a 5.7 under your house about 4 hours ago muzzy?

seisan.ird.nc...


Can't see it on Geofon or Australia

Methinks the IRD tells porcupines. No erfquack: SNZO.IU.00.BHZ.2012.051

reply to post by Me


Looking into this further I find that only 2 out of 8 earthquakes listed for today are actually correct so far.

Taking the detail from the IRD list for today:

• Northern Sumatra, Indonesia 2012-02-20 02:28:26 UTC mb 5.2 196 km - check
• Near SE Coast of Australia 2012-02-20 02:30:33 UTC mb 4.5 10 km - ???? cant find it. Possibly a miss read of the Northern Sumatra data?
  
• North Island, New Zealand 2012-02-20 05:13:59 UTC mb 5.7 513 km - nope cant find this one
  
• Queensland, Australia 2012-02-20 08:00:25 UTC mb 4.8 10 km - not according to the Australians
  
• South of Kermadec Islands 2012-02-20 10:26:07 UTC mb 4.6 10 km - check
  
• Off E. Coast of N. Island, N.Z. 2012-02-20 10:27:26 UTC MLv 4.3 383 km - there is one at 11:03 but that is around the area of the supposed 05:13
  
• East of Australia 2012-02-20 10:33:29 UTC mb 4.5 10 km - just not seeing it
  
• Fiji Islands Region 2012-02-20 10:58:23 UTC mb 5.1 10 km - nope not yet anyway
  

I think I may just consider that site to be a little on the unreliable side.

Foreshocks?

reply to post by diamondsmith


OK, now don't be taking this the wrong way.

Very interesting area of occurrence.

Since this is not an area I have studied why is this an interesting area? What is it that is interesting about it? I know they do have some big and deadly quakes in China but is this near where these have occurred?


Big location difference between USGS and EMSC




looks as if 7.2 is the biggest one in the USGS/NEIC database

Foreshocks?

Apologies, I omitted this one because it was reported at first.

I am sorry if a question create so much animosity.

reply to post by PuterMan


No 5.7 here

Yeah its a big disappointment, apart from the faster NZ reporting its pretty useless.
If its a testbed for GeoNet Rapid then there are some teething troubles to sort out.

ETA;
That location is pretty close to the 4.9 the day before, and both pretty deep

REF: 3661199

there is an outside chance Geonet did miss it, one of my first contacts with Geonet 4 years ago was to ask how they missed a 5 point.something quake in the Bay of Plenty that USGS had posted up, the reply was that they do miss some very deep quakes from time to time.

reply to post by diamondsmith

I am sorry if a question create so much animosity.

Seems I am damned if I do and damned if I don't. I asked you, as politely as I could, what was interesting about the area as it is not an area I have studied.

I did not make any comment at all on your 'foreshocks?' question.

Where is the animosity? I fail to see that anything I said was contentious in any way. If you want to consider those to be foreshocks that is open to you to do. They may be. I don't know, nor does anyone else, so you may be right. Point is I DID NOT MENTION IT.

If my asking what was interesting about the area is a problem then may I shall not bother in future. In fact may be I just won't bother full stop.

We need you to bother always please Puterman .... so many of us read your thread I'm certain , even if we don't always post.

I'll take my groupie hat off now ....
