Description:
Following the ongoing debate about suitability of short-period sensor for seismic
noise measurements at frequencies lower than 1Hz, in this study we compare recordings from
two different seismometers (Güralp CMG-3ESPC and Mark L4C-3D) installed side by side
in the GeoForschungsZentrum laboratory. The comparison carried out in terms of Power
Spectral Density and coherency analysis shows an excellent agreement between the shortperiod
and the broad-band recordings in the frequency band 0.2–20 Hz. Therefore, this result
highlights that with a calibrated short-period sensor one can obtain the same results that
would be obtained by using a broad-band seismometer in the band of engineering interest.
