The Vesuvius Observatory, a section of Italy's National Institute of Geophysics and Volcanology, is responsible for monitoring the active volcanic areas of Vesuvius, the Phlegrean Fields (Campi Flegrei), and the island of Ischia. These volcanoes, particularly Vesuvius and the Campi Flegrei are renowned throughout the world as being high risk areas because of their eruptive nature and their close proximity to extensive urban areas. The observatory employs instrument networks to enable monitoring of these areas from a seismological, geochemical and geodetic perspective.

The principal objective of monitoring is to identify and measure variations in the state of the volcanic area and to communicate the significance of these variations to the civil authorities as quickly as possible. Variations are measured by means of monitoring techniques which make use of specifically designed equipment and instrument networks.

The seismic data presented above is from 7 of the monitoring stations. To view data from a particular station click its station ID. The stations are located as follows:

..........................................OVO V and BKE V are on the slopes of Vesuvius.
..........................................SGG V is in the Matese mountains north of Caserta.
..........................................OC9 V is on Ischia.
..........................................STH V and BAC V are in the Phlegrean Fields.
..........................................STRA EHE is on Stromboli.


Each station displays the data in a similar fashion. (To view the location of the selected monitoring station click on 'mappa'). The time period labelled 'attuale', provides a real time trace of seismic activity recorded over the current 4-hour time period (GMT). The yellow bands across the trace are the first 10 minutes of each hour, each subsequent line representing a further period of 10 minutes. The lowest of the trace lines is the current situation, which is updated every 60 seconds. Data from the previous 24 hours can be viewed by selecting the appropriate time period (00 - 04, 04 - 08, etc).
