Goal: after taking this course, students will have the background knowledge necessary to start an original research project in global theoretical seismology.|
Topics: brief review of continuum mechanics and earthquake modeling. Approaches to solving the momentum equation in realistic Earth models, or ways to calculate a theoretical seismogram: homogeneous wave equation; P and S waves; eikonal equation and ray tracing; surface-wave solutions; normal-mode solutions. The problem of identifying a spherically symmetric model for the Earth (starting model for 3-D tomography).
