Subject: A diamagnetic graphite seismogram web reference

David Lamb in Texas recently was successful in obtaining
a seismogram of a quake off the coast of Nicaragua using
his experimental diamagnetic N-S seismometer. This gram
appears to be the first known amateur detected quake using
this approach with spectrographic grade graphite as the
levitated mass with a optical/light sensing arrangement.
Personally, I think the gram phases look to be quite well
defined and quite encouraging for this seismometer method
of quake detection.
