Abstract. Within the framework of the European collaborative research initiative AlpArray (, the Istituto Nazionale di Geofisica e Vulcanolgia (INGV) deployed overall 20 broad-band seismic stations in Northern Italy and on two islands in the Tyrrhenian Sea (Capraia and Montecristo) during Fall-Winter 2015.

The temporary deployment (16 stations) will run for two to three years and 4 INGV National Seismic Network accelerometric sites are now equipped with additional permanent broad-band sensors. The 16 temporary stations are equipped with REF TEK 130 digitizers and Nanometrics Trillium Compact 120 s sensors, a couple have Nanometrics Trillium 120P sensors and one a Streckeisen STS2.

For each site we describe the settings and discuss the noise levels, the site effects and the preliminary sensitivity analysis.

Short summary
We describe here the contribution of Istituto Nazionale di Geofisica e Vulcanolgia (INGV) to the AlpArray Seismic Network (AASN) in the framework of the AlpArray project (, a large European collaborative research initiative. The aim of AlpArray is carrying out cutting edge research to advance our understanding of the deep structure, geodynamics, tectonics and seismic hazard of the greater Alpine area (Alps-Apennines-Carpathians-Dinarides orogenic system).
