Seismic tomography, adjoint methods, time reversal, and banana-doughnut kernels
S U M M A R Y 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 that Fréchet derivatives for tomographic and (finite) source inversions may be obtained based upon just two numerical simulations for each earthquake: one calculation for the current model and a ...
متن کاملConstruction of finite-frequency kernels using adjoint methods
This chapter contains excerpts from “Seismic tomography, adjoint methods, time reversal, and banana-doughnut kernels,” by Jeroen Tromp, Carl Tape, and Qinya Liu. My primary contribution to this study was to adapt a 2D SEM wave propagation code to construct finitefrequency kernels. In a series of numerical experiements, I illustrated the formation of finitefrequency sensitivity kernels via the i...
متن کاملFinite-Frequency Kernels Based on Adjoint Methods
We derive the adjoint equations associated with the calculation of Fréchet derivatives for tomographic inversions based upon a Lagrange multiplier method. The Fréchet derivative of an objective function v(m), where m denotes the Earth model, may be written in the generic form dv Km(x) d ln m(x) d x, where d ln m dm/m denotes the relative model perturbation and Km the associated 3D sensitivity o...
متن کاملTime-lapse image-domain tomography using adjoint-state methods
Adjoint-state methods (ASMs) have proven successful for calculating the gradients of the functionals commonly found in geophysical inverse problems. The 3D ASM imagedomain tomography (IDT) formulation of the seismic velocity estimation problem highlights imperfections in migrated image volumes and, using appropriate penalty functions (e.g., differential semblance), forms an objective function t...
