An official at
South
Korea's seismic monitoring center confirmed a magnitude-3.6 tremor
felt at the time North Korea said it conducted the test was not a natural
occurrence. 


Australia also said there was seismic confirmation that North Korea
conducted a nuclear test.

Bob--Your interest in the Korean
Nuclear Test is a nice challenge to

consider.  My only nuke tests copied here in VA years ago were the
announced

tests in Nevada----They were given a magnitude rating after the event
(by

the NEIS)--We probably received 10 to a dozen over 2 years -the mid
l970's.

Mag. 4 barely read--Mag. 5's much better, and several over 6.0
Mag--looked

like a typical west coast/Calif. event in good detail.   Travel
time on the

events was 6 minutes, 10 seconds for us The main signature difference
was

the obvious lack of a "S" wave, as the detonation was in a
small spherical

cavity a kilometer or two underground--and appeared as a point
source.

    I understand some countries attempting tests during
the banned times

elongated their cavities to create a shear "S" componet in
the

signature.--and they appeared as a natural event.

  Perhaps this background note may be helpful.  I am certain
you will find

more information on the web pages suggested.  A Mag.5.5 or greater
from

Korea will be widely copied, no doubt by amateurs as well as
professionals--
