New Seismic Attenuation System (SAS) for the Advanced LIGO Configurations (LIGO2) [PDF]
, 2000 A new passive seismic attenuation system is being developed to replace the current passive attenuation stacks in LIGO 2, it is expected to drive the seismic contribution to the interferometer noise below any other noise source.

Seismic random noise suppression using improved CycleGAN
Frontiers in Earth Science, 2023 Random noise adversely affects the signal-to-noise ratio of complex seismic signals in complex surface conditions and media. The primary challenges related to processing seismic data have always been reducing the random noise and increasing the signal-to-

Seismic gravity-gradient noise in interferometric gravitational-wave detectors [PDF]
, 1998 When ambient seismic waves pass near and under an interferometric gravitational-wave detector, they induce density perturbations in the Earth, which in turn produce fluctuating gravitational forces on the interferometer’s test masses.

Ground Noise Survey at a Proposed Submarine Test Facility on Lake Travis [PDF]
, 1987 We conducted a brief survey of ground noise at a proposed submarine test facility on Lake Travis, northwest of Austin, Texas. The purpose of the survey was to find out the nature and level of the background seismic noise on the bottom of the lake at the ...
