Seismic Tomography with Random Batch Gradient Reconstruction

  title={Seismic Tomography with Random Batch Gradient Reconstruction},
  author={Yixiao Hu and Lihui Chai and Zhongyi Huang and Xu Yang},
Seismic tomography solves high-dimensional optimization problems to image subsurface structures of Earth. In this paper, we propose to use random batch methods to construct the gradient used for iterations in seismic tomography. Specifically, we use the frozen Gaussian approximation to compute seismic wave propagation, and then construct stochastic gradients by random batch methods. The method inherits the spirit of stochastic gradient descent methods for solving highdimensional optimization…

Frozen Gaussian approximation for 3D seismic tomography
Three-dimensional (3D) wave-equation-based seismic tomography is computationally challenging in large scales and high-frequency regime. In this paper, we apply the frozen Gaussian approximation (FGA)
Frozen Gaussian approximation for 3-D elastic wave equation and seismic tomography

We adopt the frozen Gaussian approximation (FGA) for modeling seismic waves. The method belongs to the category of ray-based beam methods. It decomposes seismic wavefield into a set of Gaussian
Tomography, Adjoint Methods, Time-Reversal, and Banana-Doughnut Kernels
SUMMARY We draw connections between seismic tomography, adjoint methods popular in climate and ocean dynamics, time-reversal imaging and finite-frequency ‘banana-doughnut’ kernels. We demonstrate
Gaussian beam migration
Just as synthetic seismic data can be created by expressing the wave field radiating from a seismic source as a set of Gaussian beams, recorded data can be downward continued by expressing the
Adjoint Tomography of the Southern California Crust
A three-dimensional seismological model of the southern California crust is developed that illuminates shallow features such as sedimentary basins and compositional contrasts across faults, and reveals crustal features at depth that aid in the tectonic reconstruction of southern California.
