Seismic noise and gravity-gradient noise

2019
Gravity gradient noise is generated by mass density changes through fluctuating gravity fields. Ambient seismic noise generated by microseismism, wind or of antropogenic origin is a possible source of such fluctuations. This work gives an overview of the impact of seismic noise and gravity-gradient noise on existing gravitational-wave detectors, and ...

STATIONARITY OF SEISMIC NOISE

GEOPHYSICS, 1968
Seismic noise has been measured in deep wells by the Geotechnical Corporation at twelve different locations and by the Shell Development Company at three deep wells. To explain the power attenuation and the coherence between vertically separated seismometers, one requires noise vibrations taken as a mixture of propagation modes, possibly surface‐wave ...

Seismic noise discrete filtering

pure and applied geophysics, 1968
By using the power density spectra of the seismic signal and the noise, it is possible to design a transfer function of an optimum (in Wiener sense) linear filter. The corresponding impulsetransfer functions dealt with in the paper were calculated as the approximation of the continuous transfer functions. This transformation can be done e.g.

Seismic attenuation from seismic ambient noise recordings

The eastern part of the Vienna Basin represents Austria's primary target for deep geothermal exploration. Effective geothermal resource assessment requires detailed knowledge of subsurface rock properties, including porosity, permeability, and fluid content.
