Description:
The Seismic Monitoring Network of Mt.Vesuvius, managed by Istituto Nazionale di
Geofisica e Vulcanologia, sezione di Napoli, Osservatorio Vesuviano (INGV-OV), currently
consists of 13 analog short period stations (9 single component and 4 triaxial),
2 digital broadband stations and a permanent seismic array (composed of 16 triaxial
sensors). Moreover 2 dilatometers are installed in the area, that are integrated in the
seismic monitoring system.
The distance among the station and between each station and the data acquisition
center varies from hundreds of meters to some kilometers. Part of the data is collected
in local Data Acquisition Centers (CAD) and then centralized at theMonitoring Center
of INGV-OV.
In recent years, information technology has become fundamental in seismic networks
and geophysical instrumentation, this includes also the data transmission systems. In
this context, the new standards for wireless networks has proved to be a useful tool for
the transmission of geophysical data. This is the reason why we have chosen to adopt
the Wireless Fidelity transmission system, based on available frequencies typical of
the IEEE 802.11h standard, which allows high capacity data traffic.
We have realized different local area networks based on WiFi technology. They can
offer a coverage to high density traffic with extensions varying from a few dozen of
meters to kilometers. Each network can be connected through a concentrator device,
called access points, and a base station, through a high-capacity system of geographic
connectivity, which will be responsible for the liaison to the Monitoring Center of
INGV-OV, where seismic data are centralized. There the data are acquired and analyzed
by automated systems, that produces parametric information in real time.
The architecture of local networks and the backbone for data transmission has been
designed to allow a modular development that is well suited for the needs of continuous
improvement of the network and the introduction of new systems for geophysical
and geochemical volcano monitoring. Currently the infrastructure manages a total of
79 channels with a 24-bit at 100 cps sampling, but the network has a much greater
potential. So the future transition of the seismic network from analog to a fully digital
equipment will be supported by this data transmission system.
