Normally I just dismiss these occassional spikes - I don't think I'm sleep
walking!  Your email has prompted me to look at the data though, see   It looks like it might be real.  The
frequency analyses shows it peaks around 4.5 Hz, which is the frequency spec of
my geophone, so not a
digitisation/amplification artifact.  I'm only 20 miles from the worlds "most
active" volcano, so it probably twitched, again.
