Terrae Didatica, 2019 Rainfall-induced variations in pore water pressures are the most common sources of significant disasters like landslides, dams’ failure, and other structural collapses. This study aimed at communicating preliminary results of seasonal monitoring of the Sobradinho landslide, Brasilia, Brazil, using ambient seismic noise.

Signal Generated Seismic Noise [PDF]
Geophysical Journal International, 1966 Summary A typical seismic pulse generates a certain amount of incoherent wavemotion due to the scattering effect of small variations in the elastic properties of the Earth. This is recorded as ‘noise’ along with the main signal. When the problem is treated statistically, mean square amplitudes of the scattered waves, and fluctuations in amplitude and ...

The Friendly Settlement of Human Rights Abuses in the Americas [PDF]
, 1999 We present a new method for estimation of seismic coda shape. It falls into the same class of methods as non-parametric shape reconstruction with the use of neural network techniques where data are split into a training and validation data sets.

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.

A U-Net Based Multi-Scale Deformable Convolution Network for Seismic Random Noise Suppression
Remote Sensing, 2023 Seismic data processing plays a key role in the field of geophysics. The collected seismic data are inevitably contaminated by various types of noise, which makes the effective signals difficult to be accurately discriminated.

Seismic arrival enhancement through the use of noise whitening [PDF]
, 2017 A constant feature in seismic data, noise is particularly troublesome for passive seismic monitoring where noise commonly masks microseismic events. We propose a statistics-driven noise suppression technique that whitens the noise through the calculation
