Comparison of straight-ray and curved-ray surface wave tomography approaches in near-surface studiesKarimpour, Mohammadkarim (author), Slob, E.C. (author), Socco, Laura Valentina (author)Surface waves are widely used to model shear-wave velocity of the subsurface. Surface wave tomography (SWT) has recently gained popularity for near-surface studies. Some researchers have used straight-ray SWT in which it is assumed that surface waves propagate along the straight line between receiver pairs. Alternatively, curved-ray SWT can...journal article 2022

Karimpour, M. (author), Slob, E.C. (author), Socco, L. V. (author)Surface Wave Tomography (SWT) is used to build shear-wave velocity models. In some studies, it is assumed that surface waves propagation follows a straight line between the source and the receiver. This assumption might be violated in near-surface studies because of high level of complexity and lateral heterogeneity. In curved-ray SWT, the...conference paper 2022

Karimpour, Mohammadkarim (author), Slob, E.C. (author), Socco, Laura Valentina (author)Joint inversion of different geophysical methods is a powerful tool to overcome the limitations of individual inversions. Body wave tomography is used to obtain P-wave velocity models by inversion of P-wave travel times. Surface wave tomography is used to obtain S-wave velocity models through inversion of the dispersion curves data. Both...journal article 2022

Karimpour, M. (author), Slob, E.C. (author), Socco, LV (author)Surface Wave Tomography is used to obtain a shear wave velocity model by inverting computed dispersion curves. Body Wave Tomography is used to obtain a longitudinal wave model through travel time inversion of picked first break travel times. Individual inversions suffer from various different limitations. Joint surface and body wave tomography...conference paper 2020
