Past, present and future of seismic metamaterials: experiments on soil dynamics, cloaking, large scale analogue computer and space–time modulations

open access: yesComptes Rendus. Physique, 2021
Some properties of electromagnetic metamaterials have been translated, using some wave analogies, to surface seismic wave control in sedimentary soils structured at the meter scale.

Mapping the basement of the Cerdanya Basin (eastern Pyrenees) using seismic ambient noise [PDF]

open access: yesSolid Earth, 2023
Ambient seismic noise acquired in the Cerdanya Basin (eastern Pyrenees) is used to assess the capability of different methodologies to map the geometry of a small-scale sedimentary basin.

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.

Spatiotemporal evaluation of Rayleigh surface wave estimated from roadside dark fiber DAS array and traffic noise

open access: yesSeismica, 2023
Seismic imaging and monitoring of the near-surface structure are crucial for the sustainable development of urban areas. However, standard seismic surveys based on cabled or autonomous geophone arrays are expensive and hard to adapt to noisy ...

Spatial and temporal variation of the ambient noise environment of the Sikkim Himalaya

open access: yesScientific Reports, 2022
Ambient noise characteristics are perused to assess the station performance of 27 newly constructed broadband seismic stations across Sikkim Himalaya and adjoining Himalayan foreland basin, installed to study the seismogenesis and subsurface structure of

Coherence-based approaches for estimating the composition of the seismic wavefield [PDF]

open access: yes, 2019
As new techniques exploiting the Earth's ambient seismic noise field are developed and applied, such as for the observation of temporal changes in seismic velocity structure, it is crucial to quantify the precision with which wave‐type measurements can ...

Shear-Wave Tomography Using Ocean Ambient Noise with Interference

open access: yesRemote Sensing, 2020
Ambient noise carries abundant subsurface structure information and attracts ever-increasing attention in the past decades. However, there are lots of interference factors in the ambient noise in the real world, making the noise difficult to be utilized ...

Seismic Periodic Noise Attenuation Based on Sparse Representation Using a Noise Dictionary

open access: yesApplied Sciences, 2023
Periodic noise is a well-known problem in seismic exploration, caused by power lines, pump jacks, engine operation, or other interferences. It contaminates seismic data and affects subsequent processing and interpretation.

Expected seismicity and the seismic noise environment of Europa [PDF]

open access: yes, 2017
Seismic data will be a vital geophysical constraint on internal structure of Europa if we land instruments on the surface. Quantifying expected seismic activity on Europa both in terms of large, recognizable signals and ambient background noise is ...
