We have no way to know. There are no records to indicate what comes first, the Volcano or the Quake or in fact if one can set the other off. All of our knowledge on both events is based solely on unproven theory and conjecture.

One could assume that they are related but you have to believe in plate theory first, so back to conjecture. I do not like plate theory at all, there is so much it does not account for. I have my own theory, but who cares? ROFL.

My guess is as good as yours as is as good as a scientist who is taught to believe in certain things. Science has major flaws in how they approach knowledge. Scientific methodology is flawed since it will only look at things in a certain way.

I understood the article to say that natural flooding of the Lake Cahuilla/Salton Sea area no longer occurs because of the Hoover dam, not that humans destroyed Lake Cahuilla.

As I understood it the Lake Cahuilla was last seen ~1700 and had nothing to do with the Hoover dam. It was during the period of this lake that the earthquakes occurred every 180 or so years.

The Salton Sea is a small area of that former lake that was artificially created by accident. Yes it is 300 years since the last quakes but those had nothing to do with Salton or the Hoover dam. The absence of the lake does NOT mean that the pressure is building as it is a well known fact that large bodies of water create pressure that causes earthquakes thus without the large body of water there are no earthquakes and no pressure. I still maintain that in my understanding they are erroneously linking disparate events.

Glad you enjoyed the photos!

I chalk up the use of "effect" instead of "affect" to the author, not an Americanism.

I see this error in English so often from people writing American - i.e. by Americans - that I am convinced this is an Americanism.

It is second as a source of irritation only to the use of English as an option on web site with other options of British English. No, we in the UK speak English. Web options should be English and American English. There is only one English and all the rest are variants.

I have to maintain a cantankerous grumpy old man image.

What about the line of volcanoes inboard of the "trench", in the Pacific Northwest?

I only said that the WBZ has very little to distinguish it as such. There is a line of volcanoes up the San Andreas as well but that is not a WBZ. There two or three lines of volcanoes in Africa and none of those are WBZs. There are lines of volcanoes in Iceland and none of those are on a WBZ. There are also a few thousand km of WBZ that have no volcanoes.

So what about them? Do they necessarily prove that Cascadia is a WBZ in the possible absence of a clearly defined depth profile? Maybe they do. I ponder these things as I do not adhere to any particular dogma and am therefore free to think out loud.

ABSOLUTELY INDEED.

I very strongly agree.

And more questioning at this time is not only apt . . . could be life-saving.

Thanks for all you do.

You obviously wanted to get that off your chest!

Sorry, could not resist.

been a while since we had one down there

Public ID 2013p780567
Universal Time October 16 2013 at 19:26:23
NZ Daylight Time Thursday, October 17 2013 at 8:26:23 am
Latitude, Longitude -47.41, 165.92
Intensity ? severe
Focal Depth 13 km
Magnitude 5.2
Location 85 km north-west of Snares Islands
www.geonet.org.nz...

Even if IRIS are kind enough to list that one there won't be much of a 3D cross section as they are pretty flat there, not like further north at -45 to -45.5 degrees, where the Wadati-whats-it is quite steep descending.
NZ 1D cross sections

That was done just using 1 months data, I should really do it again with a whole years data, it would probably show the Wadati-Benioff zones of NZ better.
Too bad that you can't load your own data into that IRIS 3D thingybob

Thanks Muzzy, great work.

I see the option to load in longitude/latitude co-ordinates into the 3D viewer . . . not sure how one defines a rectangle thereby. Haven't looked closely at it. Guess I need to given my interest.

Fascinating views with the 3D viewer.

I haven't looked. How close was that last quake to you?

Agreed.

In the spirit of Halloween and kicking dogma to the curb*, I'm linking Don L Anderson & Warren B Hamilton's essay, Zombie Science & Geoscience.

*just to be clear, I have never & would never kick a dog

I think these two are on the right path in stripping plate tectonics to its bare minimum. For example, thinking of convection as only an upper mantle feature, driven by top-down cooling of plates, not heating from the bottom, slab rollback as an under appreciated mechanism, and the superfluous mantle plumes glommed onto PT theory.

about 1000km from me.
I was wrong, amazing how quickly you forget, there was a 5.1 same area 60 days ago.
goo.gl...

does anyone else collect LDEO data off the LDEO page?
I missed 06-10 October.
Don't know how I managed that, it rolls over every 7 days and I have a look most days, but from time to time I forget to update the list on the file I keep for each month.
They don't keep Archives, which is why I do, but every now and again I make a hash of it by missing some days at the bottom of the list.

Way to go, Muzzy--keep them suckers 1,000+ km away from you! LOL.

Thanks for all you do hereon. you and Puterman are top flight in service to the members hereon . . . as well as to the lurking planet.

Still fiddling with the IRIS 3Dmodeller

The new style is a bit dark, but none the less there are enough events recorded by IRIS to make a clearer cross section. I used the last 6 years data.
Here is the cross section where I live.
The old style beneath.
I have worked my way up from the south to the -39 to -40 band so far.
On the old one I did every 0.5 degrees of latitude


May only appeal to Kiwis who know where they are looking at, maybe needs a map of the whole country with the degrees marked on it.
If I could make the orbs opaque, it could be possible to build a complete 3D model of New Zealand with each latitude layer on top of each other, which would show the complete shape of the edges of the Tectonic Plates and how they overlap all the way down the country Ahhh what I could do if I had funding (didn't have to work at a real job)

Great 3D pics. You have a link to them?

They seem deeper than most I've seen. More like Japan's. Sigh.

reply to post by BO XIAN

Well no I didn't save the links, didn't think I'd need them again
But I just went back and found the approx. rectangle for that particular area.
this is it here

One feature that would make things easier on that program would be the ability to enter some lat/long co-ordinates to create the rectangle you are looking for, at the moment it is a trial and error task to get it close to eg -41 and -42 lat, took me about 20 attempts. I use some location that I am familiar with and get the lat/long off the Google Earth using the grid. eg -41 is just be low D'Urville Island.

I'll post a link to the new version of all of NZ Seismic Cross Sections when I get the last few done tomorrow,

One thing that cropped up while I was doing that was the location of that 348km deep quake, it is directly under the Marshall Range, which is unique in that it is part of what I call the NZ "geological button", check it out on Google Earth or Google Maps (terrain), -41.10, 172.43
almost a perfect circle around the mountains created by the river

FANTASTIC.

THX FOR YOUR LINK:

Yeah. It seems real clumsy to try and delineate a suitable rectangle.

Much appreciate your 20+ tries.

What kind of fault is involved at that point . . . strike slip or what?

Another quake swarm at Tjörnes Fracture Zone, more precisely: Grimsey lineament. Most of them seem to be very shallow and not very strong.
