As my interest involves the depth of Earthquakes we have just had another very deep Earthquake
Only a Magnitude: 3.6 in magnitude but the Depth is of interest.
It occurred at a depth of 416 km one of a few over the last week.
Most we have been having are at a depth between 2 km and 16 km with the od one between 100 km
and 150 km, usually unnoticeable.

So it is quite a big jump down to the 400 km mark.

NZST: Sunday, June 22 2014 at 10:01:04 am
Maximum intensity ?: unnoticeable
Depth: 416 km
Magnitude: 3.6
Location:  40 km north-west of Kawhia

Located NOT far from where we are,     but some km's south of us.


Here are some interesting comments regarding very deep earthquakes:


http://geology.about.com/od/earthquakes/a/aa_deeEQs.htm
1st the environment

The Earth gets hotter by about 1 degree C with each 100 meters of depth on average.

Combine that with high pressure underground and it's clear that by about 50 kilometers down,
on average the rocks should be too hot and squeezed too tight to crack and grind the way they do
at the surface.

Thus deep-focus quakes, those below 70 km, demand an explanation.

Thus there are plenty of candidates for the energy behind deep earthquakes at all depths
between 70 and 700 km—perhaps too many.

And the roles of temperature and water are important at all depths as well, though not precisely known.

As scientists say, the problem is still poorly constrained.

Deep Earthquake Details

There are a few more significant clues about deep-focus events.

One is that the ruptures proceed very slowly, less than half the speed of shallow ruptures,
and they seem to consist of patches or closely spaced subevents.

Another is that they have few aftershocks, only one-tenth as many as shallow quakes do.
And they relieve more stress; that is, the stress drop is generally much larger for deep than shallow events.

Until recently the consensus candidate for the energy of very deep quakes was the phase chang
from olivine to olivine-spinel, or transformational faulting.

The idea was that little lenses of olivine-spinel would form, gradually expand and eventually connect
in a sheet. Olivine-spinel is softer than olivine, therefore the stress would find an avenue of sudden release
along those sheets. Layers of melted rock might form to lubricate the action, similar to superfaults
in the lithosphere, the shock might trigger more transformational faulting, and the quake would slowly grow.

Then the great Bolivia deep earthquake of 9 June 1994 occurred, a magnitude 8.3 event
at a depth of 636 km.
Many workers thought that to be too much energy for the transformational faulting model to account for.

Other tests have failed to confirm the model.
But not all agree.
Since then, deep-earthquake specialists have been trying new ideas, refining old ones, and having a ball.

It's been some time since I posted in this forum, but I thought it Prudent to bring to others attention,
there appears to have been a sudden behaviour change in our daily earthquakes !

We are now getting Earthquakes between 200 km to 700 km deep, most between 200 km and 350 km.


Very few shallow earthquakes felt, yesterday and today in NZ.


Here is a List of 'Moderate' to 'Sever' Earthquakes felt since I last Posted in this forum ...

That's an interesting change, too bad I don't have the slightest idea why it happened.

Stay safe.

[The Matrix Traveller]

Hi ArMap... I will do my best to stay safe I appreciate any concern on your part.


I am still watching very closely every day, and will report any further changes.

I find the behaviour of the Earths crust fascinating Armap.

Still be interesting to see IF my R.V. experience comes to fruition or Not.   


I don't really want it to..... but if it is to..... as I am unable to do anything about
I may gain more understanding regarding the mechanics of this Program. (Earth)
