The main contributions at that time for the analysis of these recordings came from the Japanese seismologist K. Aki [16] in 1957. See more In geophysics, geology, civil engineering, and related disciplines, seismic noise is a generic name for a relatively persistent vibration of the ground, due to a multitude of causes, that is often a non-interpretable or unwanted component See more The amplitude of seismic noise vibrations is typically in the order of 0.1 to 10 μm/s. High and low background noise models as a function of frequency have been evaluated globally. See more Characterization of subsurface properties The analysis of the ambient vibrations and the random seismic wavefield motivates a variety of processing methods used to characterize the subsurface, including via power spectra, H/V peak analysis, dispersion curves See more Research on the origin of seismic noise indicates that the low frequency part of the spectrum (below 1 Hz) is principally due to natural causes, chiefly ocean waves. In particular the globally observed peak between 0.1 and 0.3 Hz is clearly associated with the … See more Under normal conditions, seismic noise has very low amplitude and cannot be felt by humans, and was also too low to be recorded by most … See more Direct measurements of noise properties cannot directly give information on the physical parameters (S-wave velocity, structural … See more The acquisition chain is mainly made of a seismic sensor and a digitizer.
