&lt;br/&gt;Abstract: Seismic monitoring of active volcanoes has different and sometimes contrasting&#xD;
requirements. The peculiar features of volcanic seismicity makes an interactive&#xD;
system more complex than required for typical seismic monitoring.&#xD;
Intense seismic swarms of small magnitude earthquakes need a rapid but consistent&#xD;
processing for tracking in real time the evolution of an ongoing volcanic&#xD;
unrest. At the same time a comparison with the past record for detecting&#xD;
patterns still observed or anomalous behaviours is needed. Furthermore a correlation&#xD;
between different parameters as event magnitude and depth, event&#xD;
occurrence rate and volcanic tremor amplitude may be required. Finally, a&#xD;
rapid exchange of information among scientists located worldwide can be&#xD;
important for drawing conclusions about the evolution of a crisis.&#xD;
The first task can be fullfilled by an automatic seismic processing system, followed&#xD;
by a manual revision from expert seismologists. The second and the&#xD;
third can be simply accomplished storing the results of the processing in relational&#xD;
databases, that very well suited for such applications. The last task can&#xD;
be simply achieved by making the dataset accessible on-line thour a web server,&#xD;
in a friendly and interactive way.&#xD;
On the basis of the experience matured on the automatic seismic monitoring&#xD;
system of Stromboli ([2]) the research team of Monitoring Centre of I.N.G.V.&#xD;
“Osservatorio Vesuviano” started developing a similar software infrastructure&#xD;
for the monitoring of Neapolitan volcanoes.&#xD;
The existing databases: GeoVes, with supervised analysis, and Web Based&#xD;
Seismological Monitoring (WBSM) system, with automatic location, have been&#xD;
joined into a single friendly graphical interface aimed at improving the data&#xD;
accesibility and efficiency of the monitoring system.</description>

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

&lt;br/&gt;
&lt;br/&gt;Abstract: Mt. Vesuvius (South Italy) is one of the most hazardous volcanoes in the world. It&#xD;
has been very active from 1631, when a violent subplinian eruption occurred, until&#xD;
1944, with the last, medium size, eruption. So far Mt. Vesuvius is quiescent and in&#xD;
the last 60 years the population of the surrounding areas strongly increased. Its activity&#xD;
is characterized by a fumarolic field inside the crater and a moderate seismicity,&#xD;
with hypocenters mainly clustered in a volume about 2-5 km beneath the crater zone.&#xD;
The monitoring network of Mt. Vesuvius is composed of 15 seismic stations (seven&#xD;
3 component and 9 vertical) and two seismic arrays, one with just 3 stations and the&#xD;
other one with 48 channels. The remote instruments continuously transmit the data to&#xD;
the recording centre by using different technological solutions. The data are collected&#xD;
in the monitoring centre of the Vesuvius Observatory - INGV and automatically processed&#xD;
in order to obtain meaningful information in real time. This system allow to&#xD;
immediately retrieve the significance of the recorded phenomena and to early communicate&#xD;
the state of the volcano to Civil Authority.</description>

&lt;br/&gt;
&lt;br/&gt;Abstract: Campi Flegrei is an active volcanic area posing a serious threat over Naples. Half of&#xD;
the city lies inside the caldera rim. The volcano has shown in the last 30 years different&#xD;
episodes of unrest, the most recent is still ongoing. For this reason the monitoring of&#xD;
this volcano is a fundamental task. The current seismic network consists of 8 short&#xD;
period and 5 broadband stations. The seismic monitoring is complemented by 2 infrasonic&#xD;
sensors and 3 dilatometers. The recent seismicity has been characterized by&#xD;
swarms of volcano-tectonic and long-period events. The network geometry allows an&#xD;
accurate location of VT events with a detection threshold of magnitudes less than 1.0&#xD;
Some VT events have been recorder also by the infrasonic sensors showing interesting&#xD;
similarities. LP events have been recorded by both short period and broadband&#xD;
stations. The polarization analysis performed over the broadband recordings is an important&#xD;
tool for the real time detection of such events, related to the dynamics of the&#xD;
hydrothermal system. The ongoing developments consists in a progressive increasing&#xD;
of the number of broadband digital stations and infrasonic sensors, in improving the&#xD;
accuracy of hypocenter locations by using a 3D velocity model and in the implementation&#xD;
of new automatic techniques aimed at the detection, classification and analysis&#xD;
of seismic events.</description>
