The goal of this paper is to provide an overview of the current state of the art in seismic
tomography, and trace its origins from pioneering work in the early 1970s to its present …

Publisher Summary This chapter describes a variety of schemes for tracking the kinematic
evolution of high frequency seismic waves in heterogeneous 2-D and 3-D structures. Where …

Early identification of abnormal regions is crucial in preventing the occurrence of
underground geotechnical disasters. To meet the high-accuracy detection requirements of …

In 2001 and 2002, a temporary array of 72 seismic recorders was deployed across northern
Tasmania (SE Australia), with the aim of imaging the underlying crust and upper mantle …

We present a practical grid-based method in 3-D spherical coordinates for computing
multiple phases comprising any number of reflection and transmission branches in …

Constraining geophysical models with observed data usually involves solving nonlinear and
nonunique inverse problems. Neural mixture density networks (MDNs) provide an efficient …

Seismic tomography is a methodology to image the interior of solid or fluid media and is
often used to map properties in the subsurface of the Earth. In order to better interpret the …

Imaging using information derived from the cross-correlation of the ambient seismic
wavefield at different stations has recently become an important tool in seismology. We here …

Seismic surface wave tomography is a tried and tested method to reveal the subsurface
structure of the Earth. However, the conventional 2-step scheme of inverting first for 2-D …

This article introduces PyKonal: a new open‐source Python package for computing travel
times and tracing ray paths in 2D or 3D heterogeneous media using the fast marching …
