Territorial seismic monitoring
SPECIFICATIONS
The seismic acquisition system called SETA
SYSTEM has been developed by MAE in jointventure
with partners of high profile, such
as: the National Institute of Oceanography
and Experimental Geo-physics, OGS, located
in Trieste, and the National Institute of Geophysics
Georgiano, IGEM, located in Tbilisi.
The system allows to create architectures
for seismic networks in digital telemetry
with 24-bit resolution, using the two basic
units of the system or the RX-16 receiver,
with 16 inlets for as many transmitting
units TX-3, properly located on the territory
that must be monitored. The S.E.T.A system
has been developed with the purpose
to create a vast territorial network of seismic
monitoring stations, completely independent
in terms of energy and radio communications,
able to monitor the seismic/
micro-seismic activity of the territorial area
where it is located, 24 hours a day. The remote
units are installed in suitable rural containers,
which characteristics are developed
based on the specifications of each system.
These are usually fed by battery packs with
high autonomy, re-charged through solar
panels or other solutions. The digital transmitting
unit TX- 3 AD is equipped with 3 inlet
channels with 24-bit resolution, and allows
to use velocimeters with 1/2 Hz frequencies
or mono and three-axial accelerometers, in
addition to geophones of different frequency.
It is stored inside a sturdy steel container,
it codes and transmits via radio the signals
coming from the seismic sensors to
the Data Collection Station, with which it is
in constant connection, where one or more
RX-16 units have been installed, which receive
and decode the data acquired locally
by the remote units. The data transmitted
by the RX-16 in real time can be then treated
with different types of analysis software
and stored through proper procedures, thus
allowing the creation of an archive of seismic
events of the geographic region object of the
study. The data collected allows to know and
constantly monitor the seismic activity in
the monitored region. The system has been
conceived to work with automatic recording
and signalling modes of the events that occur
on all the remote stations connected to
the system. The data coming from the remote
stations of the network can be viewed
on the terminals of the Data Collection Centre
24 hours a day.
