Needless to say USGS and the lap dog have it at 4.8

You sure it is a 5.8. Sure is not showing anywhere. Nothing hardly at all on LISS and it is very small on SNZO SNZO.IU.00.BHZ.2011.273

Phase data on USGS has virtually nothing above 5mb. They are quoting 4.8mb and 4.7ML

reply to post by PuterMan


(with that quake) being on the west side of the Kermadec Ridge SNZO doesn't pick those up so good, only the east (Trench) side
Decent trace on Urewera on the East Cape though

Here's the map for recent US quakes.
earthquake.usgs.gov...

Forgetting the west, the eastern US is very quiet. The only areas showing activity over the last week are Ohio and NMSZ. I know it's cliche', but it seems too quiet. I liked it when there is a lull. Because very soon, we'll see a return in activity and it is very interesting to follow the newest batch. Also, worldwide quakes are still relatively modest.

"it's quiet, a little too quiet."

I tried to find a video compilation of movies with the quote. Surprisingly, no one's done one yet.

reply to post by Robin Marks


Hi regularly keep an eye on this thread, so hope you don't mind me asking this...could the quietness be due to extra meteorite activity?
I can't put a finger on it , just wonder if there could be a connection with the NEAS peaking at the moment?

OK, will look at that.

Now cop a load of this.

Um beg pardon what eh excuse me? Emphasis by me in both cases.



Nothing on EMSC www.emsc-csem.org... (that may not hit the right page as time moves on. You need to move yourself to the 18th)

Is this a mistake? If so it is a very big one! See it here in the 8-30 day list

I have emailed USGS to query this.

ETA: Had to snag it.

In all honesty, I don't think meteors would change earthquake activity. I am more inclined to believe that the lull is because the east has released lots of energy over the last few months and is out of steam. Actually, I'm not even going to listen to myself. I don't know. But I've very curious to see what happens next.

Want a laugh?

Where would you find a siesmo station called Dead Sheep, or Gay Alien, or Valley Of Doom 1?

Take a look at the XO network! which is part of the University of Leicester experimental network (United Kingdom) and has seismos all over the world - many with some very off names!.

Nice hum happening in Yellowstone at Norris Junction.

... obligatory 2nd line.

reply to post by LexiconV


I'm not terribly interested in, or knowledgeable about Yellowstone's transmission system. But I do know enough to know it's just a technical problem. There's nothing happening at Yellowstone. It's quiet- a little too quiet.

I may just rant about this particular subject on the Yellowstone thread. The lack of activity has me wondering about the previous two major swarms. In retrospect, I am now starting to think we came very close to have an eruption, a little too close.

some good ones in there alright. Students eh!
Theres a location that pops up on the NZ lists quite a lot on the Akatarawa Fault just on the other side of the Tararua Mts from where I live, when you do a placename searchof the co-ords it comes up as Three Skulls Rd there must be a story behind that name, I've driven past the turnoff many times buthave never turned up the road .............. perhaps in the fear of becoming the Fourth Skull
a pretty narrow winding road in the mountains

reply to post by PuterMan


indeed I see on that usgs link here too, but notice there is no phase data
must be a mistake, a 4.6 japan style sure doesn't make a 6.9 under any conversion
I ususally scan the lists for 6's and check the phase data if they look close to a 7, but don't recall checking that on out

Close to the Auckland Island on 'the crack' running south.

Alaska

whoa~!!
are we having a problem !!?? !! Click on the global view and Alaska is nearly dead center of the globe.. and on Rencent quakes....

and here

in the past 7 days

Nevada anyone....

MAJO.IU.00.BHZ.2011.261

The seismo for that one.

Plot for the day


No 6.9 That I can see. The quake at around 1300 is Sikim.

reply to post by PuterMan

looks like a 4.6 on that siesmo

reply to post by PuterMan


you are more accurate than usgs
"W of the South Island" did the person who wrote the text bother to look at their own map
I'd call it S of the South Island or Auckland Islands.
Of course they use the Flinn-Engdahl seismic and geographical regionalization scheme to get their locations but surely use some common sense here, some people (like me for instance) would see that location on the list and be looking for something off Fiordland.
Just saying

Although its outside Geonets coverage area they have it on the Recent Quakes list anyway (not on the search results yet)
5.9 Puysegur Trench (the crack)


Harping on about the usgs location still, you know I have never seen these FE Regions mapped, apart from the 757 larger areas which puts the whole of NZ in Region 11.
apparently there are 1713 sub regions according to EMSC

The region name is called "Flinn-Engdahl +" region. Flinn-Engdahl (FE) regions have been defined in 1974 (Flinn et al., 1974) and revised in 1995 (Young et al.; 1995). The boundaries of these 757 regions are defined at one-degree intervals and therefore differ from irregular political boundaries. An improvement of classical FE regions has been proposed by B. Presgrave from the USGS/NEIC and called FE+ regions, in order to better bit political boundaries. Those 1713 FE+ regions are used by EMSC to better labelled the region where an earthquake occurred.
