Seismologists construct images of the Earth's interior structure using observations, derived from seismograms, collected at the surface. A common approach to such inverse problems is to build a single ‘best’ Earth model, in some sense. This is despite the fact that the observations by themselves often do not require, or even allow, a single best-fit Earth model to exist. Interpretation of optimal models can be fraught with difficulties, particularly when formal uncertainty estimates become…

On the nature of the P-wave velocity gradient in the inner core beneath Central America
We conduct an experiment to investigate whether linearity in the observed velocity gradient in the volume of the inner core sampled by the PKP ray paths beneath Central America is a robust
Convergence Tests for Transdimensional Markov Chains in Geoscience Imaging
It is shown that appropriately chosen scalar conversions of the models could retain similar statistical ensemble properties as geologic projections created by rasterization, while maintaining the statistical characteristics of the ensemble.
Tomographic filtering via the generalized inverse: a way to account for seismic data uncertainty
Tomographic-geodynamic model comparisons are a key component in studies of the present-day state and evolution of Earth’s mantle. To account for the limited seismic resolution, ‘tomographic

Abstract. Parametric geological models such as implicit or kinematic models provide low-dimensional, interpretable representations of 3-D geological structures. Combining these models with
Inversion of receiver functions without deconvolution—application to the Indian craton

Bayesian trans-dimensional full waveform inversion: synthetic and field data application
Seismic full waveform inversion (FWI) is a state-of-the-art technique for estimating subsurface physical models from recorded seismic waveform, but its application requires care because of high

Recent years have seen a substantial increase in the amount of available seismic catalog data. Extracting information from these data, on a case-by-case basis is gradually becoming infeasible. In

We review the present status of global and regional mantle tomography and discuss how resolution has improved in the last decade with the advent of full waveform tomography and exact numerical

S U M M A R Y Inversion of surface wave data for crustal and upper-mantle structure is a staple of passive seismology, particularly since the advent of techniques enabling surface wave dispersion


Transdimensional tomography with unknown data noise
SUMMARY A meaningful interpretation of seismic measurements requires a rigorous quantification of the uncertainty. In an inverse problem, the data noise determines how accurately observations
A self-parametrizing partition model approach to tomographic inverse problems
Partition modelling is a statistical method for nonlinear regression and classification, and is particularly suited to dealing with spatially variable parameters. Previous applications include
Parsimonious Bayesian Markov chain Monte Carlo inversion in a nonlinear geophysical problem
Summary A key element in the solution of a geophysical inverse problem is the quantification of non-uniqueness, that is, how much parameters of an inferred earth model can vary while fitting a set
Trans-dimensional geoacoustic inversion.
This paper develops a general trans-dimensional Bayesian methodology for geoacoustic inversion that results in environmental estimates that quantify appropriate seabed structure as supported by the data, allowing sharp discontinuities while approximating smooth transitions where needed.
Receiver function inversion by trans‐dimensional Monte Carlo sampling
SUMMARY A key question in the analysis of an inverse problem is the quantification of the non-uniqueness of the solution. Non-uniqueness arises when properties of an earth model can be varied

Transdimensional inversion of receiver functions and surface wave dispersion
This work presents a novel method for joint inversion of receiver functions and surface wave dispersion data, using a transdimensional Bayesian formulation and shows that the Hierarchical Bayes procedure is a powerful tool in this situation, able to evaluate the level of information brought by different data types in the misfit, thus removing the arbitrary choice of weighting factors.
