Title: High quality seismological recordings from the SN-1 deep seafloor observatory in the Mt. Etna region
Title of journal: Geophysical Research Letters
Series/Report no.: Vol. 32
Publisher: American Geophysical Union
Issue Date: 8-Apr-2005
DOI: 10.1029/2004GL021975
Abstract: We show over 4 months of 3-component broadband seismometer data from the SN-1 seafloor multidisciplinary observatory, deployed offshore of Eastern Sicily (Italy) at 2105 m b.s.l. The SN-1 spectra show background noise levels above 0.1 Hz similar to levels at a nearby ground station. An important noise source below 0.1 Hz is caused by tilt of the sensor induced by sea currents. Seismic noise levels above 0.01 Hz are strongly dependent on Etna volcanic activity. In spite of these intense noise sources, SN-1 recorded many local, regional and global events. The quality of seismic recordings confirms the validity of the installation procedure and good ground coupling of the 3-component broadband sensor, suggesting that SN-1 can be proposed as permanent observatory in this high seismic and volcanic hazard area.
