Nondestructive testing of railway embankments by measuring multi-modal dispersion of surface waves induced by high-speed trains with linear geophone arrays

Seismica
To effectively address engineering challenges and risks, it is crucial to characterize mechanical properties of near-surface environments. The Multichannel Analysis of Surface Waves (MASW) has proven to be a valuable active seismic imaging technique by ...

Deghosting, Demultiple, and Deblurring in Controlled-Source Seismic Interferometry

International Journal of Geophysics, 2011
With controlled-source seismic interferometry we aim to redatum sources to downhole receiver locations without requiring a velocity model. Interferometry is generally based on a source integral over cross-correlation (CC) pairs of full, perturbed (time ...

Imaging Torfajökull's Magmatic Plumbing System With Seismic Interferometry and Phase Velocity Surface Wave Tomography

Journal of Geophysical Research - Solid Earth, 2019
Torfajökull volcano, Iceland, has not erupted since 1477. However, intense geothermal activity, deformation, and seismicity suggest a long‐lasting magmatic system.

Seismic Interferometry at the TIMO2-network, Germany

, 2012
Using seismic interferometry, we analyze the seismic noise wavefield around the city of Landau, Germany. The crosscorrelation functions (CCFs) are investigated with respect to signals which might contain information on the underground and its temporal variations.

Extrapolation of seismic land streamer data using interferometry

Scientific Reports
Land streamer seismic acquisition is increasingly adopted for near-surface geophysical applications due to its operational efficiency and mobility. However, the short source-receiver offsets and weak coupling inherent in land streamer systems limit their

Separation of Body and Surface Wave Background Noise and Passive Seismic Interferometry Based on Synchrosqueezed Continuous Wavelet Transform

Applied Sciences
Passive seismic interferometry is a technique that reconstructs virtual seismic records using ambient noise, such as random noise or microseisms. The ambient noise in passive seismic data contains rich information, with surface waves being useful for the

Review of temporal variations of underground medium based on seismic waves

地球与行星物理论评
As a vibrant and ever-evolving planet, the Earth has a dynamic evolution process spanning more than a dozen orders of magnitude from seconds (e.g., seismic rupture) to millions of years (e.g., mantle convection).

Multi-technique SAR coseismic deformation retrieval and fault modeling of the 2025 Mw 7.7 Myanmar earthquake

Progress in Earth and Planetary Science
This study investigates the coseismic displacement field caused by the Mw 7.7 earthquake that struck Myanmar on March 28, 2025, along a segment of the Sagaing Fault, a well-known, right-lateral strike-slip fault.
