Estimation of splitting functions from Earth's normal mode spectra using the neighbourhood algorithm

Pachhai, Surya; Tkalcic, Hrvoje; Masters, Guy


The inverse problem for Earth structure from normal mode data is strongly non-linear and can be inherently non-unique. Traditionally, the inversion is linearized by taking partial derivatives of the complex spectra with respect to the model parameters (i.e. structure coefficients), and solved in an iterative fashion. This method requires that the earthquake source model is known. However, the release of energy in large earthquakes used for the analysis of Earth's normal modes is not simple. A...[Show more]
