The level of microseismic noise is studied at locations in the Western Carpathians where, apart from the vertical component of the noise, also its horizontal component was recorded by a broad-band seismograph. The amplitudes of the permanent noise in the horizontal component ranged from 10 to 83 nm and, at most locations, the predominant periods T>0.45 s, although the predominant periods of the vertical component in the Carpathian region are mostly within the interval T ≐ 0.24–0.37 s.
