Hello PSN:


Id like to hear from you guys (or gals :-) )
why some quakes will show no Shear waves.
Or possibly, so small you cant see them with the naked eye.

1. Will shear waves pass through the Mantel ?

    (Mantel is partially liquified ?)

2. Does the solid core spin faster by one rotation in four hundred years ?

(I heard this a long time ago but not sure its for real ?)

Don't just point me to some web site,

Id like to hear your own opinions on these ideas ?

3. I wound a coil out of like AWG30 copper wire
It had a Resistance of 86 ohms and it seems to have
a generator constant of about (0.242V/(IN/sec))
Does that sound realistic for a not-so-carefully
wound coil (Wound like a bobbin of thread).

I used 4 rare earth magnets to determine the constant
with about 1 inch of gap where the coil was located.

I figure by this it would be best to pay a pro
to wind a proper 1K coil out of AWG30 wire
or a 10K coil out of 40AWG copper wire ??

With this "G" constant I need a gain of about X11
over what I currently am using built be the pros.

4. Is it possible to develop a standard amateur Velocity
sensor which we might all get together somehow and have wound
by a pro ? (Its just a coil, but must be well wound)
Like maybe the two options I just specified of AWG30 at !kohm
  and AWG40 at 10Kohm I know the makers want a terribly expensive
setup fee. Someone like Larry might keep them for future amateurs
who want to build their own sensor stuff ??
That's about 9400feet of wire in whatever gauge (AWG) for a single 
copper coil. The two coils to be together in a single package ?

The solenoids have a too small center opening (id) it probably should be 
an inch or so inside diameter possibly an inch thick coil.
something easily handled. Then, how to get a G of at least 2.54V/(in/sec).

5. Do most seismic waves arrive from below or the sides , and
     can you tell direction by time delay between two stations or more ?
     Not by drawing lines on a map ? Not by N/S E/W knowledge of motions.

6. is it possible to build an omnidirectional sensor
    instead of three directionals' to see the motion.

Ive thought of these a long time, just now to be asked.
Comments ?

Regards,
geoff
