This temporary network was deployed in the area of the town of Vittorio Veneto in the period 12/2003-02/2004 with the aim of estimating the local seismic amplification and site effects. A total of 13 seismic stations were deployed for more than one year to record in continuous mode (Fig. 1).

A first group of 10 stations (of which 3 on rock outcrops) were deployed in the quarter of Serravalle ---the historical centre of Vittorio Veneto--- in the period January-July 2001. During this period, a total of 40 earthquakes was recorded and localized.

Further to a seismic swarm occured in December 2003 in the Alpago-Cansiglio area, near to Vittorio Veneto, a second group of 3 stations (one on bedrock, as a reference site) was deployed in Ceneda quarter, one of the Vittorio Veneto’s areas mostly damaged during the M5.8 Alpago-Cansiglio earthquake of 1936. A total of 70 earthquakes was recorded by the stations throughout the 2 mounths of the seismic monitoring.

Some details on the sites and the instrumentation deployed is given in Table 1.
