The monitoring seismic network is the main control system
of natural seismicity of the soil or caused microseismicity
by human activity as injection or extraction of
hydrocarbons and fluid / gas in the subsoil.
The network is composed by remote seismic station
equipped with seismometers or accelerometers, located on
the territory. The sensors characteristics must be adapted to
the detection of local and regional seismicity, considering
both the frequency bands both the dynamics of signals.
Every single stations are temporally synchronized by
GPS antenna and they are managed in real time by
remote processing centres using high speed digital data
transmission or satellite technologies.
The seismic and microseismic networks allow seismologists
to determine the earthquakes hypocentral parameters with
magnitude considerably low; it is estimated that a network
is able to record a magnitude even below M = 1.0.
