Sensitivity of Seismic Noise Correlation Functions to Global Noise Sources

open access: yesJournal of Geophysical Research: Solid Earth, 2018
Surface waves in seismic noise correlation functions are routinely exploited for tomographic studies. However, the observation and proper interpretation of body waves is considerably more difficult.

Online Jump and Kink Detection in Segmented Linear Regression: Statistical Optimality Meets Computational Efficiency

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of sequential (online) estimation of a single change point in a piecewise linear regression model under a Gaussian setup. We demonstrate that certain CUSUM‐type statistics attain the minimax optimal rates for localizing the change point.

Improving electromagnetic noise removal from seismic data using innovative EM receivers: a novel hybrid approach

open access: yesDiscover Applied Sciences
Considering the large extent of conventional seismic projects for hydrocarbon exploration, the electromagnetic (EM) noise from power grids is an inevitable challenge.

Multifractal and Entropic Properties of Seismic Noise in the Japanese Islands

open access: yesFractal and Fractional
This article examines the behavior of seismic noise fields over the Japanese islands recorded by the F-net seismic network for 1997–2025. This paper uses nonlinear noise statistics: the entropy of the wavelet coefficient distribution, the Donoho–Johnston

Synchronizing seismic networks with ambient noise [PDF]

open access: yesGeophysical Journal International, 2008
SUMMARY The technique of retrieving Green’s functions by pairwise correlation of a random wavefield is used to estimate the stability of the timing system of a seismic network. The method is demonstrated with data from a network consisting of stations with four independent clocks and GPS-receivers.

Home Safe Home: Safety Gains Through Telework During the Covid‐19 Pandemic

open access: yesLABOUR, EarlyView.
ABSTRACT This paper exploits exogenous shifts in work organisation during the Covid‐19 pandemic to study the implications of hybrid and remote work arrangements on occupational safety. Combining accident registers and household survey microdata from Hungary, we are able to address potential selection and reporting bias, and reliably identify the ...

Monitoring Saturation Changes with Ambient Seismic Noise and Gravimetry in a Karst Environment

open access: yes, 2018
Saturation changes can be monitored with ambient seismic noise. We present a new and nondestructive tool to investigate deep and heterogeneous vadose zones.
