Hello all,

Micro-earthquakes have high frequancy but low energy. This is common for
earthquakes that are from -2.0ML and up to 2.50ML in size. The best way
to detect micro-earthquakes is with a seismomter that has main frequancy
of 1Hz and up to 4,5Hz. The only expection from this appears to be if
the earthquake is magma or volcano activited.

Regards,
J=F3n Fr=EDmann.
