| Zusammenfassung |
| One of the main actions of the AlpArray European initiative is the deployment of a dense
seismic broad-band network, that complements the existing permanent stations. This will
ensure a spatially homogeneous seismic coverage of the greater Alpine area for at least
two years, allowing a great number of innovative scientific works to be carried
out.
Our contribution to the AlpArray Seismic Network consists in the deployment of 24
temporary broad-band stations: three in Switzerland, twelve in Italy, three in Croatia, three in
Bosnia and Herzegovina and three in Hungary. This deployment is lead by ETH
Zurich and founded by the Swiss-AlpArray Sinergia programme by SNSF, and is
the result of a fruitful collaboration between five research institutes. Stations were
installed between Autumn and Winter 2015. Our installations are both free field and
in-house and consist of 21 STS-2 and 3 Trillium Compact sensors equipped with
Taurus digitizers and 3G telemetry sending data in real time to the ETH EIDA
node.
In this work, we present sites and stations setting and we discuss in details the characteristics
in terms of site effects and noise level of each station. In particular we analyse the power
spectral density estimates investigating the major source of noise and the background noise
related to seasons, time of the day, human activities and type of installation. In addition we
will show examples of data usage – i.e. earthquake locations, noise cross correlations,
measures of surface wave dispersion curves.
