| Zusammenfassung |
| ISA (Italian Spring Accelerometer) is a very broad–band high–sensitivity accelerometer,
result of a long activity devoted to the development of instruments for space use (room
temperature gradiometers ad accelerometers). It can equally well be used for geophysical
studies. It is the underlying component of a wide variety of instruments, as a high–sensitivity
seismometers (sensitivity 10-10 g--Hz-- under 10-1 Hz) and field seismometers,
gravimeters and gradiometers (which employ a sensitivity 108 g--Hz- under 10 Hz).
Many instruments have been built and operated, in a variety of environments, including the
multi–parameter sea–floor station GEOSTAR (GEophysical and Oceanographic Station for
Abyssal Research). Following a description of the accelerometer, a review of the various
types of measurements will be given, discussing its many applications. These range from
seismic measurements to environment characterization (e.g., underground cavities
reconnaissance) to geodetic studies. This instrument is therefore suited for use in wide
warning networks for e.g. seismic monitoring: its integration into such networks will be
discussed. |
