Ambient seismic noise tomography at Ekofisk

GEOPHYSICS, 2015
We have studied an approximately 40-hr recording from the Life of Field Seismic array installed over Ekofisk field to assess whether the recorded ambient seismic energy was suitable for passive seismic surface-wave interferometry. Passive seismic interferometry aims to retrieve virtual seismic sources by crosscorrelation.

Geotechnical site characterization with 3D ambient noise tomography

GEOPHYSICS, 2023
We develop a new 3D ambient noise tomography (3D ANT) method for geotechnical site characterization. It requires recording ambient noise fields using a 2D surface array of geophones, from which experimental crosscorrelation functions (CCFs) are then extracted and directly inverted to obtain an S-wave velocity ([Formula: see text]) structure.

Ambient Noise Tomography in Central‐South Mongolia

Chinese Journal of Geophysics, 2015
AbstractRelying on cooperation projects in Mongolia, “Observation and modeling on the geomagnetic, gravitational field and deep structure in the Far East Areas”, we got dense seismic array data in the area for the first time. By using the vertical component of continuous data, recorded by 69 broadband seismic stations from Aug. 2011 to Jul.

Road sinkhole detection with 2D ambient noise tomography

GEOPHYSICS, 2021
Seismic methods are often used for detection of precollapsed sinkholes (voids) under roadways for remediation to minimize risks to the safety of the traveling public. Although active-source seismic methods can provide accurate subsurface profiles, they require closing the traffic flow for hours during testing and may potentially cause sinkhole ...

Ambient noise tomography of Eyjafjallajökull volcano, Iceland

Journal of Volcanology and Geothermal Research, 2017
We present a shear-velocity model for the Eyjafjallajokull stratovolcano, based on ambient seismic noise tomography applied to seven months of data from six permanent stations and -10 temporary sei ...

Ambient seismic noise tomography at Valhall

SEG Technical Program Expanded Abstracts 2011, 2011
Although permanent ocean-bottom cables installed at the Valhall field record high-quality and repeatable active seismic surveys, even in absence of active seismic shooting the array can record an abundance of seismic energy. Seismic interferometry of 29 hours of passive seismic data generates omnidirectional Scholte-wave virtual-sources at very low ...
