Seismic tomography is a powerful tool for illuminating Earth structure across a range of
scales, but the usefulness of any image that is generated by this method is dependent on …

This second edition of The Illustrated Wavelet Transform Handbook: Introductory Theory and
Applications in Science, Engineering, Medicine and Finance has been fully updated and …

We propose a method to invert surface wave dispersion data directly for 3-D variations of
shear wave speed, that is, without the intermediate step of phase or group velocity maps …

We present a tomographic model of radially anisotropic shear velocity variations in the
Earth's mantle based on a new compilation of previously published data sets and a variable …

In geophysical inversion, inferences of Earth's properties from sparse data involve a trade-off
between model complexity and the spatial resolving power. A recent Markov chain Monte …

本文利用喜马拉雅二期科学探测台阵的678 个地震台站及26 个固定台站记录到的9,641
个地震共约160000 条远震P 波走时数据, 采用基于稀疏约束的多尺度层析成像方法 …

What makes a seismogram look like a seismogram? Seismic data sets generally contain
waveforms sharing some set of visual characteristics and features—indeed, seismologists …

We demonstrate that higher order Fréchet derivatives are not negligible and the linear
Fréchet derivative may not be appropriate in many cases, especially when forward …

This work considers the reconstruction of a subsurface model from seismic observations,
which is known to be a high-dimensional and ill-posed inverse problem. Two approaches …

We have developed a wavelet-based double-difference (DD) seismic tomography method.
Instead of solving for the velocity model itself, the new method inverts for its wavelet …
