Low frequency seismic noise acquisition and analysis with tunable monolithic horizontal sensors

摘要

In this paper we describe the scientific data recorded mechanical monolithic horizontal sensor prototypes located in the Gran Sasso Laboratory of the INFN. The mechanical monolithic sensors, developed at the University of Salerno, are placed, in thermally insulating enclosures, onto concrete slabs connected to the bedrock. The main goal of this experiment is to characterize seismically the sites in the frequency band 10~(-4) ÷10 Hz and to get all the necessary information to optimize the sensor.
