Turning standalone seismometers into strainmeters using tidal strain and ambient noise: a feasibility study

Earth, Planets and Space
Solid Earth is subjected to gravitational tidal deformations in the nanostrain order. We focus on detecting seismic shear wave velocity changes caused by this phenomenon.

Time reversal and plane-wave decomposition in seismic interferometry, inversion and imaging

, 2013
textThis thesis concerns the study of time reversal and plane-wave decomposition in various geophysical applications. Time reversal is a key step in seismic interferometry, reverse time migration and full waveform inversion.

Study on crustal deformation of Wenchuan Ms8.0 earthquake using wide-swath ScanSAR and MODIS

Geodesy and Geodynamics, 2011
This paper presents a broad-range study of the co-seismic deformation field of Wenchuan Ms8.0 earthquake by ScanSAR interferometry. The results show co-seismic displacements ranging from −19.8 on the footwall side of the seismogenic fault to 73.6 cm on ...

Deep Shear Waves Model of the Venice Lagoon from Seismic Noise Interferometry [PDF]

openThe objective of my thesis is to develop a deep shear wave model of the Venice Lagoon using seismic noise interferometry. This method involves time cross-correlation of seismic noise recorded between two stations: one on the island of San Servolo and

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 ...
