| Abstract: | The paper presents a comparative analysis of the intrinsic noises of seismometers operating at Kamchatka seismic stations: CMG-3TB (GURALP), CMG-5TD (GURALP), CMG-6TD (GURALP), GMS-AC-73i HHV (GeoSIG), SM3os (GEOTECH+), S5Sos (KF GS), and SM3kv. It is shown that the dynamic range of the seismometers is narrower at low frequencies in the area of weak signals. |
