Eikonal Equation Approach for Seismic Velocity Tomography from Micro-Earthquakes

摘要

In this work we present an eikonal equation-based approach to wave velocity tomography inside a micro-seismic event cloud. For this approach we consider the receiver as a source and all micro-seismic events as receivers. The difference of the events' origin times and their P- and S-phase arrival times at the receiver provide the base to construct a travel time field from which we derive the underlying wave velocity field.
