Abstract
<p>Mt. Vesuvius (southern Italy) is one of the most hazardous volcanoes in the world. Its activity is currently characterized by moderate seismicity, with hypocenters located beneath the crater zone with depth rarely exceeding 5 km and magnitudes generally less than 3. The current configuration of the seismic monitoring network of Mt. Vesuvius consists of 18 seismic stations and 7 infrasound microphones. During the period 2006-2010 a seismic array with 48 channels was also operative. The station distribution provides appropriate coverage of the area around the volcanic edifice. The current development of the network and its geometry, under conditions of low seismic noise, allows locating seismic events with M&lt;1. Remote instruments continuously transmit data to the main acquisition center in Naples. Data transmission is realized using different technological solutions based on UHF, Wi-Fi radio links, and TCP/IP client-server applications. Data are collected in the monitoring center of the Osservatorio Vesuviano (Italian National Institute of Geophysics and Volcanology, Naples section), which is equipped with systems for displaying and analyzing signals, using both real-time automatic and manual procedures. 24-hour surveillance allows to immediately communicate any significant anomaly to the Civil Protection authorities.</p>

Vesuvius is one of the most dangerous volcanoes as a consequence of the high urbanization of the surrounding areas [De Natale et al 2011].In the 19th century an increasing interest in the Earth studies leaded to the foundation of the Osservatorio Vesuviano, the first volcanological observatory in the world [Owens 2013]
Vesuvius is the first known monitoring network on a volcano. It started working in 1856 with the installation of the first electromagnetic seismometer designed by Luigi Palmieri
Summary
Vesuvius is one of the most dangerous volcanoes as a consequence of the high urbanization of the surrounding areas [De Natale et al 2011]. In order to locate these events, it was decided to increase the number of stations in this area by installing modern digital broadband stations Vesuvius were installed using a low-power digital acquisition system, named GILDA [Orazi et al 2006, 2008], designed and developed at the Osservatorio Vesuviano to fit requirements of remote installation places Thanks to these new installations it was possible to better delineate a seismogenetic volume close to the crater area which was, previously, poorly known [Giudicepietro et al 2010, D’Auria et al 2013].
