Comrad "Red Cloak" you ask why there are so many earthquakes occurring at 6.2 miles in depth; that is a good question. One that I can only touch
on, but I can honestly tell you that there must be a much longer and better explanation than what I will be able to give you, but here goes....
It depends where the earthquakes strike in the world, as to what depth they are going to strike at in general. Each region of the world, and each
strip along side one of the plate boundaries has its own particular depth at which earthquakes strike. So, it really depends on the location.
It seems to me (not proven scientifically yet) that the different regions with "similar depths" feed earthquakes from their linked areas. Meaning
that an earthquake cell in a linked area in the distance that releases its energy adds to the energy at the absorbing energy cell that is down stream
from the earthquake cell that releases its energy. So, what I'm saying is that earthquakes get some of their energy from earthquake cells that
release energy at approximately the same depth or higher, yet they are in fact far distant from each other.
At the same time, you have to understand that something down below is usually creating the abnormal pressure to exist at some certain point or fault.
That something is probably a liquid; whether it is incompressible water or magma.
If you are up in Montana, up in Yellowstone National Park, you realize that the area is underlain by water that is heated up by near surface magma,
causing periodic geysers of water to erupt. But when you study the geyser, it is different from an earthquake or earthquake cell building up its
When a geyser builds up its pressure during its cycle, the pressure builds and builds, and then "suddenly" the pressure releases. When an
earthquake cell or common earthquake builds up its pressure during one of its cycles, it's pressure builds and builds, and then it holds that
pressure for a period of usually 4-7 minutes, and then the pressure suddenly releases. The amount of time it holds the pressure specifies which
earthquake or earthquake cell you are watching. So... if you are watching one particular earthquake in one particular area, and its holding time is
approximately 5 minutes, then every time its daily cycle comes, depending on which day of the cycle it is, then you would always expect it to release
around the 5 minute mark, plus or minus approximately 1 minute or less.
When you are looking at the radiation that is emitted from an earthquake coming through the walls of the place you are living in, and you start
marking the walls with pieces of tape, in order to see exactly what the outline really looks like all at once, then you can be surprised at what you
Most all of the time, the top of the radiation field is flat, just like you would expect some liquid rising from below would look like after it hits a
barrier up above it that it cannot move or penetrate. The picture you usually see if you are looking at the refracted radiation is usually many times
wider than it is in height in general. Down below this you will see an upside down cone, where you can see that the liquid spread out in the cone
shape as it comes up through the different strata below until it hits the impermeable layer and can only spread out below it.
When there is enough pressure below this impermeable barrier, then the barrier itself breaks and lets some of this liquid which must be limited in its
extent in some manner or another escape. Sometimes if you look deeper, you will see there is more than one layer deep down in the fault. Now
remember, what you are looking at is refracted radiation, and you can be at tremendous distances and see all of this, and I'm talking hundreds of
miles away for the larger earthquakes. You'll of course want to be broad side to it in order to see as much as you can, sometimes what you will see
is very jagged upward or downward parts to the fault under abnormal pressure.
But, what I guess I'm trying to say is that the barriers that seem to quake the most, are probably weaker than other barriers or strata of material
located at different depths. It all seems to work just like plumbing in your house, and there is nothing overly scientific about it.
Basically, if a huge earthquake would take place far in the unknown future, we would expect it to strike at approximately the same depth as all of the
other earthquakes have previously struck at for the particular area, unless noted otherwise.
Basically, deep underground at some depth, another earthquake or earthquake cell in the distance released their energy, in so doing, it might have
pinched together a deep underground crevasse that liquid was flowing through at some particular unknown speed. Well, since the crevasse is now
pinched off and the liquid cannot flow through it as it normally did, then it seeks another route. That spot becomes like an underground dam, and the
liquid behind the dam starts building up pressure, and more pressure, and if something doesn't break somewhere above, then the liquid whatever it may
be, just starts backing up, maybe hundreds or thousands of miles back up stream.
At different points along this upstream area, the pressure there becomes detectable also, and is noted as being increased, by pressure exerted on the
rock causing a PIEZO ELECTRIC EFFECT meaning the crystals in the rock give off electricity and radiation when they come under abnormal stress. But
sooner or later the area where the original crevasse got pinched off, a nearby area sometimes cracks under pressure, usually called "the trigger
earthquake", and soon an inrush occurs from all that backed up water and boom you have a massive earthquake that was caused by inrushing liquid from
spots upstream that had held back pressure. Those detectable spots upstream, slowly lost their pressure as the crest at their particular area
So, in areas that are noted for having earthquakes at 6.2 miles in depth, there must be a particular barrier that is typical of that particular
location and many other locations apparently. That barrier, I would think would have to be possibly more brittle, and possibly much thicker than
other strata located below it, to be the toughest upward barrier for the liquid to penetrate.
