Research progress of the extraction body waves from ambient noise

open access: yes地震科学进展, 2021
The exploration of the deep structure of the earth is the core part of geophysical research. Seismic body waves can penetrate deep into the earth with a high resolution and it is an indispensable technical means for studying the internal structure of the

Combining seismology and spectropolarimetry of hot stars [PDF]

open access: yes, 2014
Asteroseismology and spectropolarimetry have allowed us to progress significantly in our understanding of the physics of hot stars over the last decade. It is now possible to combine these two techniques to learn even more information about hot stars and

Retrieving time-dependent Green's functions in optics with low-coherence interferometry [PDF]

open access: yes, 2015
We report on the passive measurement of time-dependent Green's functions in the optical frequency domain with low-coherence interferometry. Inspired by previous studies in acoustics and seismology, we show how the correlations of a broadband and ...

A raypath-consistent receiver correction in PS converted wave processing through seismic interferometry: New application for tropical zones New application for tropical zones

open access: yesUniversitas Scientiarum, 2019
The estimation of static corrections is an issue still unsolved for PS converted wave processing. Due to the PS converted wave usually arriving at the surface at non-zero angles, the surface consistent approach is no longer valid, and corrections ...

Improving Surface Wave Retrieval From Traffic Noise by Deconvolution of the Decomposed Wavefield

open access: yesEarth and Space Science, 2023
Traffic noise is an important type of passive seismic data because it usually includes strong dispersive surface wave components and can be easily accessed.

Continuous isolated noise sources induce repeating waves in the coda of ambient noise correlations

open access: yesSeismica, 2023
Continuous excitation of isolated noise sources leads to repeating wave arrivals in cross correlations of ambient seismic noise, including throughout their coda. These waves propagate from the isolated sources.

Passive seismic imaging of the Lower Palaeozoic in the Sudret area of Gotland, Sweden [PDF]

open access: yesSolid Earth
Passive seismic data were acquired together with active seismic data along a 2.8 km long profile in the Sudret area of Gotland, Sweden, as part of a feasibility study for storage of CO2 below the Baltic Sea. Seismic interferometry using cross-correlation

Estimating frequency-dependent shear wave velocity in near-surface sediment based on seismic interferometry

open access: yesEarth, Planets and Space, 2023
Near-surface seismic shear wave is a basic tool for seismic investigations. However, its frequency-dependent property is not fully investigated, especially by the in situ observation method.

Shear wave structure of a transect of the Los Angeles basin from multimode surface waves and H/V spectral ratio analysis [PDF]

open access: yes, 2020
We use broad-band stations of the ‘Los Angeles Syncline Seismic Interferometry Experiment’ (LASSIE) to perform a joint inversion of the Horizontal to Vertical spectral ratios (H/V) and multimode dispersion curves (phase and group velocity) for both ...
