AMBIENT SEISMIC NOISE VARIATIONS BEFORE EARTHQUAKES IN THE BAIKAL RIFT SYSTEM

open access: yesГеодинамика и тектонофизика, 2022
This paper proposes a method to observe the pre-earthquake features based on the variations in ambient noises using local moderate and strong seismic events as an example.

Ambient noise levels in north central Italy

open access: yesGeochemistry, Geophysics, Geosystems, 2006
The characteristics of background seismic noise in north central Italy have been investigated by means of velocity power spectral analysis within the frequency range 0.1–15 Hz. The method proposed by McNamara and Buland (2004) has been applied to estimate the probability density function (PDF) of power spectra computed for ten different stations. Since
