Hi all

Has John Tacinelli looked for insects?
I sometimes get events that are at first glance 
indistinguishable from large teleseisms.
These are due to pinhead sized daddy long legs spiders
setting up house inside the seismograph draft
shield.  If you scale it up, it is equivalent 
to a human being setting a mass like an aircraft
in motion.  I call these events "spiderquakes"

Cheers all

Danie Overbeek.
