Seismic noise and gravity-gradient noise [PDF]

, 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 ...

Ocean wave sources of seismic noise [PDF]

Journal of Geophysical Research, 2011
International audienceNoise with periods 3 to 10 s, ubiquitous in seismic records, is expected to be mostly generated by pairs of ocean wave trains of opposing propagation directions with half the seismic frequency.

Some interesting seismic noises

SEG Technical Program Expanded Abstracts 1984, 1984
ABSTRACT This paper suggests that the identification of seismic noise increases our ability to evaluate deeper drilling targets. Seismic noise, as illustrated in basic, unstacked data, is shown to contain clues which the seismic processor may use to improve the resolution of the seismic section.

The spectrum of seismic noise

Bulletin of the Seismological Society of America, 1962
Abstract The seismic noise spectrum in the frequency range 0.5 to 31.5 cycles per second is presented graphically for a number of sites over a wide geographical range. Except for a small anomalous effect near 2 or 3 cycles per second, the ground particle motion curves are observed to decrease smoothly with increasing frequency at a rate ...
