I'll try to look into it later in the morning. There are other battles with computers and networking going on downstairs at the moment. A bit of a war zone among the computer specialists.

Seems to only be on LMH, not on the station closer to the summit LAS, and the signals only appear at high frequency. Station map - volcanoes.usgs.gov...

Looks like real ground motion, but something near or at the surface, from a quick look,

Been raining for 4 hours here at my place, since yesterday elsewhere in NZ, after almost a month with very little rain and very few earthquakes, forecast rain for the next 7 days, pretty much over the whole country.
Yesterday only 3 quakes across the islands, with the second lowest release of energy in 24hrs this year, the equivalent of 2.071 tonnes of TNT released. March 12th was the lowest with just 1.804 TTNT released, just 2 days before a week of Mag 5's (Caswell Spur 5.4, W of Secretary Island 5.2, Rotorua 5.0, and finally Irene River 5.6, which was the last Mag 5)
It is hard to get old weather data for the country as a whole, all the web weather sites show just individual local stations rainfall, so its hard to tell what was going on the week of 12-20/03/2102 over the whole country to see if there is a relationship between wet weather and quantity and size of earthquakes.
I had a look at this a few years back, following the barometric pressures and comparing to where earthquake events were occurring, but I couldn't find a match at all. Have never noticed an increase of quakes at any particular time of year either.
Some say that water lubricates the faults, but we are talking lots of water here, like floods or if it rains or a week or more.

Will be interesting to see if there is a pickup in numbers and/or larger sized quakes over the next week.
If there is, the Moon pundits will likely claim "ah ha, 2,3,4 whatever days after a super moon"

The PP is spreading from the Pacific-Antarctic Ridge at the south end and the Southern and Northern East Pacific Rise through the middle so is heading both NW and NE.

it is called surge tectonics and is an alternative theory.

I have a better reference somewhere but this should get you going on it.


Puterman, It is very easy to rubbish my opinions, I can do so myself.

If I may suggest, work from a positive position first, make your best guess and then try and rubbish it. I have been studying this for a long time as you know and I take a more all encompassing approach. I see the collective rather than the isolated.


Did I miss something here or are you inviting me to rubbish your theory? I was not doing so by the way.

If you are inviting me then I am afraid you are out of luck (
) because I like surge tectonics, even if you did not know that was what it was called.

You would think that with things being quiet it would be easier to ID the traces on the graphs.
Nope.


Not having much luck with LISS NZSO this morning, 3 quakes that none of the networks have ID'd.

08/05/2012 03:10-03:20 (looks like PacAnt Ridge or Maquarie Is, or could be Vanuatu)
08/05/2012 06:30ish (has P wave at 06:48ish and LR wave at 06:58ish, quite a long package, could be long way off)
08/05/2012 13:20ish (smaller than 03:10 but about the same length)

No I did not know it was called surge tectonics. Cool name.

My biggest concern with subduction zones is the amount of pressure a large subduction quake will impose on the molten material under it. That pressure has to be released and a large downwards thrust movement is likely to throw significant pressure that must be released. Pressure releases of this magnitude are handled in the Earth's system by pressure release valves otherwise called volcanoes.

The big question on my mind is will a large down thrust in Cascadia translate enough pressure to cause the Yellowstone group of volcanoes to pop. Even a minor 'pop' could cause Yellowstone Lake to release a steam event of biblical proportions. I think this scenario is likely.

I find much of what I study to be too restrictive in that a zone here or a zone there is what is being studied. We need to see the macro, that is to take an holistic approach with the realization that the entire world is moving to continually find a harmonious balance.

The balance approach is a holistic approach. The big questions are, how does the force get transmitted through the plates and how long does it take.

Obviously outside gravitational forces may have an effect and often do, but only if a region is ready to slip into a more harmonious position. The moon, sun and planets do not cause earthquakes. They can trigger points already stressed. More and more information (mostly guesswork at this point) is being formulated on how the Sun can heat the core in much the same way as a microwave oven cooks food. Magma expands and this is I think our main concern in the near future.

Until the Pacific Plate reaches an interim balanced point the West Coast of the US and Canada is under dire threat and this correction must happen. The question is when and we just don't knoe enough about the Holistic Earth to be able to answer that. To me it will be sooner as in shortly!

Very, very, very quiet on the worldwide quake front.

I feel either the E. coast of Japan or the W. coast of Peru is going to EXPLODE!!

I hope I am very, very mistaken!

Give it a few more days


Gotta wait till next week when the planets line up...heh heh

Still no word on those unidentified quakes, but there have been two others with almost identical traces since I posted that
09/05at 00:12
and 01:53
on SNZO

No data from USGS since 2012/05/08 23:55:42 or Geofon since 2012-05-08 22:23:50 thats 4 and a half hours ago

Whats going on eh?, there HAVE been earthquakes

Those last 2 ARE showing on Marble Bar and Narrogin, Australia and Namibia, so odds they are Southern Ocean rather than Vanuatu.

Na, the ones I'm on about were 3-4 hours ago.
That one probably won't show on SNZO anyway, its too deep @ 519.4 km

Are you sure that a thrust (surge) subduction event would trigger ANY volcanic activity along the West Coast?
Has that happened before?
The reason I ask is that in the back of my mind it happens the other way around.
In many cases big earthquakes either happen at the same time or AFTER an eruption..
I recall this is the case in Alaska anyway, maybe Vanuatu and definitely New Zealand.
I'll look into it a bit more, get back to you in a year or so, how many volcanos are there worldwide subject to subduction?

And how many are on Spreading Ridges (eg Iceland) or isolated hotspots (eg Hawaii), nothing is clear cut

Try to see the whole, the way things are interconnected. If a Volcano blows it relieves pressure from the surrounding magma zones. If these zones are supporting a portion of a plate and the support is gone then an earthquake can quite happily follow an eruption. The reverse can of course happen as well!

I could not agree more, nothing is clear cut, but, it is all interconnected and cause and effect follow each other like lovers.

Hi Muzzy,

I am hoping you could answer a question for me. Could you explain to me why the Fiji area has the deepest earthquakes. I did try to find an answer to this but I can't really find a decent answer.

Tonga-Fiji has the most deep earthquakes because the tectonics there are very fast, up to 20 cm per year, and the subducting slab is very cold, because of the fast motions combined with subduction of old oceanic plate.

Ref for thermal parameter (see p. 41) books.google.com... 7-J15lq9s&hl=en&sa=X&ei=4YOqT4fvCsWYiQL8y43rDw&ved=0CFEQ6AEwAw#v=onepage&q=thermal%20parameter&f=false

If you're asking why deep earthquakes apparently extend to 720 km under Tonga, but only 650-700 in other deep zones, we think that earthquakes can only occur in the upper mantle, and the phase transition the marks the upper mantle-lower mantle boundary occurs at higher pressure when the rock is cold, hence the boundary is slightly deeper where the very cold Fiji slab is sinking.

SNZO 09-05-20 1518

Geofon nailed one of them


F-E Region: [color=EDDA74]Balleny Islands Region
Time: 2012-05-09 04:18:28.1 UTC
Magnitude: 4.7 (mb)
Epicenter: 178.94°E 65.36°S
Depth: 10 km
Status: M - manually revised

geofon.gfz-potsdam.de...

435km NE of Bruce Island volcano in fact, south of New Zealand, on a Transform Fault on the Pacific-Antarctic Ridge, where a line of seamounts coming out of the Ross Sea converge (don't forget active Erebus volcano down there)
I think you can bet the other 3 quakes (one on yesterdays graph) are same area, about the same size.
Significance? to my way of thinking that magnitude size is just about right for a volcanic eruption (sic Chile last year) so 4 in a 24 hour period is of interest, if their locations are close together that is.
Otherwise its just the Antarctic Plate sliding past the Pacific Plate towards Macquarie Island

they go deep to avoid Bananyorama's wrath


Seriously I don't know, John's likely right.
Its the same as under the Andes where you get deep quakes on the other side in Brazil and Argentina resulting from subduction along the Peru Chile Trench.
The Kermadec and Coleville Ridges are the south western Pacific version of the Andes, just that they are under the sea, New Zealand is like the highest peak along the Ridge
