Sorry to be the Accuracy Policeman here but you got Perigee and Apogee backwards

Perigee was Jul 7 14:05 369565 km New Moon +6days 5hours
Apogee will be Jul 21 22:48 404356 km Full Moon+6days16hours

As you are correct as I flip-flopped them at 3am+ in the morning by the own chart that I got them

Moon

I've just added the Kermadec Is. 7.6Mw and aftershocks to my NZ 7 Days and 30 Days maps and lists (link in my signature), I thought such a significant event should be given the recognition it deserves, even if the data is USGS and a bit suspect as to accuracy.

This Geonet quake also a bit suspect, either its a mistake (it was the weekend after all) or there are some big changes going on around NZ, never seen a quake anywhere near that side of Northland before, ever

What other difference?

Just reading what you said again are you saying one trace for each earthquake in a separate graph - a bit like the overall drums page?

Just for a moment assuming that this is what you are saying, you would have to:

• identify the earthquake from the list
  
• get the SAC file portion for a defined time span around the quake
  
• Hi pass/Lo pass filter the file for 1 to 6 Hz say (preferably on a 1 Hz sample rate)
  
• Create a seismo plot from that
  
• Stitch them all together into a larger image
  
• Relax and have a cuppa
  

Quite a lot of work without it being done in a program! I will think about it!

edit on 10/7/2011 by PuterMan because: (no reason given)

Looks like a lot of work.

What I was thinking is a graph like LISS SNZO but showing all the quakes for the day, not just the big ones (which most of the time are away from NZ anyway)
The reason I said it might not be possible is that the traces show up as different sizes on each different stations graphs depending how close they are to the earthquake.
even BUD is no use as RPZ or URZ don't show on SNZO and viseversa

It was just an idea, I've stopped doing the daily timeline and depth graphs now as it was too much work too.

Weekly Data Files.7z

If anyone is interested that is the complete list of Icelandic earthquakes from 1995 Week 1 to 2011 Week 27 (Now) in the original 'listi' format from the Vedur (IMO) ftp pages. It is just over 4Mb in 7z format and 16.2Mb when expanded.

Week 01 of 2001 is missing, and has been missing for over 18 months now. Time I started asking questions!

I didn't even feel the 4.3 in Somerfield Christchurch tyoday. It knocked power out in some parts of the city though (and not the nearby suburbs!): Link (The Press)

Would love for you to ask lots of questions of various professional powers that be on such matters.

Wish there was a ping list so we could be alerted by you about the responses you get back.

Have you concluded by now that there CERTAINLY is

or

ALMOST CERTAINLY IS some skullduggery going on with the data at some venues?

reply to post by BO XIAN


I honestly think in this case they are probably unaware that the data is not accessible in view of it's age. I can't really see why they would have any reason to remove just one single week out of 16 and a half years of data. Much as I like a good conspiracy I have to say that in this case I don't think one is afoot.

Magnitude 6.7 quake hits the Philippines, USGS reports.

Update:...Quake off Philippines had a magnitude of 6.6, NOAA Pacific Tsunami Warning Center reports.

Now it's reported as a 6.2

Isn't that a pretty significant difference to be off by?

earthquake.usgs.gov...

Interesting event at Negros, Philippines.

This article was written just yesterday (11 July)... before the 6.2 today:

ACOLOD CITY, Philippines—The Philippine Institute of Volcanology and Seismology (Phivolcs) has been closely monitoring the Negros trench following five earthquakes, the strongest one at a 5.2-magnitude, that hit Negros Occidental. Ishmael Narag, Phivolcs Seismology Division officer-in-charge, said Monday afternoon that the 24-hour watch started when the last tremor hit at 10:10 a.m.

And now it's a 6.4.

It is like musical chairs. Guess what the magnitude will be when the seismo stops.

I must admit that looking at the phase data I thought they would bring it down to a 5.9 BUT you see it is a 6.4 Mi/MiP, or a 5.9 ML, or a 5.2 mblg and if you are really nice it could be a 6.1 MS

When all is said and done it was a biggish earthquake!

Here's a quick and sloppy map of California and something I have been noticing.

[atsimg]http://files.abovetopsecret.com/images/member/a32d1232c339.jpg[/atsimg]

We have a slurry of quakes in So Cal west of the San Andreas.
Numerous and some medium large quakes in No Cal east of the SA.
and lots of quakes in Central Cal right on the SA.

It all just makes me nervous.

In our thread of the antipodal point researching. You may or may not believe in. I would assume most dont. One poster on the thread said pressure was building in the area you was talking about and was concerned for Southern California and the LA area. Said pressure was, in his opinion building up there along the plates and causing pressure building in the South Pacific Sea. Today, there was a quake that you probably already know, at the East South Pacific Rise. Just like he said, so your concern may well be valid.

I'm going to be struggling to post over the next 10 or so days, laptop fan is playing up, its off to China (or Japan can't remember where it was made its a HP) under warranty
Have had to start from scratch on our office computer, didn't even have Firefox on it so you can imagine what I have to go through. Also its XP and Windows 2005 so I can't even open Windows 7 Excel files that I use to work the data and graphs.
Luckily 80% of those were CSV Excel files which it does open.

I've got a few sites up on Speed Dial (incl ATS), its amazing how quickly you forget how you set things up the first time.
Should be interesting to see if I can still do my NZEQ Blog.

SO where is Google Earth on this old rig ......................

Hopefully we don't get a spate of big quakes!
I'm only allowed 2 hours in the afternoon and whatever I can get done before 8am.

At least its not DialUp

There was just a couple of strong quakes in Italy...... is that due to the volcanic activity or what??

No I wouldn't think so, there are no volcano's anywhere near.
The nearest volcanics are the Larderello geothermal area with the Lago Vecchienna crater, 116km to the SW (according to Google Earth )

Getting close to home......
