Within the framework of the European collaborative research initiative AlpArray (<a href="http://www.alparray.ethz.ch" target="_blank">http://www.alparray.ethz.ch</a>), 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. <br><br> 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. <br><br> For each site we describe the settings and discuss the noise levels, the site effects and the preliminary sensitivity analysis.
