Estimation of Uncertainties of Full Moment Tensors using 1D and 3D Earth Models
Abstract
Uncertainty quantification is especially important for small events, such as chemical explosions, and for full moment tensors, for which the model parameter space is six-dimensional, rather than four-dimensional for a typical earthquake shear fault. In seismology we are often at the limit of signal-to-noise, and the quantification of uncertainties is necessary to allow one to make statistical-based interpretations. This project has three objectives: (1) to develop a modern computing framework for full moment tensor inversion and uncertainty quantification for 1D and 3D Earth models; (2) to understand uncertainty quantification of moment tensors in realistic, synthetic numerical experiments; and (3) to quantify the uncertainty in source types for Nevada Test Site explosions and earthquakes.
