Lithospheric reflection imaging by multidimensional deconvolution of earthquake scattering coda

Seismic interferometry (SI) for body waves offers the opportunity to utilize highfrequency scattering coda from local earthquakes to obtain a detailed reflectivity image of the lithosphere. In this thesis it is demonstrated that classical SI methods are seriously affected by circumstances that are typical of field data and that multiple...

Retrieval of Elastodynamic Reflections From Passive Double-Couple Recordings

Virtual Green's functions obtained by seismic interferometry (SI) can provide valuable reflectivity data that can complement tomographic inversion schemes. However, virtual reflections are affected by illumination irregularities that are typical of earthquake-induced wavefields recorded by the receiver array. As a consequence, irregular...

Passive body-wave interferometric imaging with directionally constrained migration

Passive seismic interferometry enables the estimation of the reflection response of the subsurface using passive receiver recordings at the surface from sources located deep in the Earth. Interferometric imaging makes use of this retrieved reflection response in order to study the subsurface. Successful interferometric imaging relies on the...

Full-field multidimensional deconvolution to retrieve body-wave reflections from sparse passive sources

Our objective is to complement lithospheric seismic tomography with an interferometric method to retrieve high-resolution reflectivity images from local earthquake recordings. The disadvantage of using local earthquakes for the retrieval of reflected body-waves is their usual sparse distribution. We propose an alternative formulation of passive...

Full-field MDD for body-wave reflections from passive transient-sources under severely limited and irregular illumination conditions

Seismic interferometry (SI) presents a set of inexpensive and noninvasive methods that can be applied to any array at the surface to retrieve virtual body-wave reflection responses from earthquake recordings. Conventional SI by cross-correlation requires recordings of wavefields in lossless media generated by a smooth continuous distribution of...

A method to retrieve an improved high resolution reflection response from HiCLIMB array recordings of local earthquake scattering coda (PPT)

We discuss a method to interferometrically retrieve the body wave reflection response from local high-frequency scattering coda wave fields with the purpose to obtain an input dataset suitable for the application of advanced exploration-type imaging methods

Analysis of 2D homogeneous space solutions of the seismoelectric P-SV-TM mode for interferometric purposes

Seismic and electromagnetic imaging methods both provide the geophysicist with different types of medium parameters. Seismic methods are sensitive to the elastic properties of the medium, while electromagnetic methods are sensitive to the electric properties. In porous-saturated media, these two wave fields occur as a coupled system, which is...
