Im just interested in first time of arrival
as well as distance and depth but not so much
about axis. Possibly magnitude. I think the plane of arrival
can be extracted from three or more sites with
timing which is both accurate and precise.
At least GPS quality.


I modeled three dimensional motion and found the motion
to be represented by a noisy orbit about a seemingly
point of focus. Sort of reminded me of how an electron might orbit
a nucleus. Some motion seemed possibly this way
or that but it looked mostly like just a noisy random orbit.
But you got to realize it was only one quake I looked at
this way from one person. I wrote the program to update the picture
and show a history with the third dimension of up or down
above the Z zero as blue or red history.
So it looked like a standard graph of a single point but was
blue or red depending upon the Z axis being positive
or negative. It was hard for me to create this program even tho
the idea seemed simple to my mind.

Just vectored the X,Y,Z axis to create a seemingly moving BMP image.
Using Power Basic Compiler.

I might have saved the program or results but
it was a while ago and I have several System crashes since.
I might have to write the program for the PSN files
again if anyone is interested.
It was fun to get PowerBasic compiler to do this.
It is not a Fortran Program.

Happy New Year all yous guys/gals in PSN land.
