Trans-dimensional inversion of microtremor array dispersion data with hierarchical autoregressive error models

Dettmer, Jan; Molnar, Sheri; Steininger, Gavin; Dosso, S.E.; Cassidy, J.F.

Description

This paper applies a general trans-dimensional Bayesian inference methodology and hierarchical autoregressive data-error models to the inversion of microtremor array dispersion data for shear wave velocity (vs) structure. This approach accounts for the limited knowledge of the optimal earth model parametrization (e.g. the number of layers in thevs profile) and of the data-error statistics in the resultingvs parameter uncertainty estimates. The assumed earth model parametrization influences...[Show more]
