GEOPHYS 293: Seismic imaging using earthquake and ambient-noise data

Seismic imaging using earthquake and ambient noise data has developed into one of the most powerful tools to study the Earth's internal structure from regional to global scales. This class will give a (slightly futuristic) account of this topic.n In the first part we will focus on regional- to global-scale full-waveform inversion (FWI) using earthquake data. We will review the theoretical foundations of visco-elastic FWI, discuss data requirements, study modern techniques to quantify resolution using second-order adjoints and random probing techniques, and finally highlight some recent applications.In the second part of this class, we will extend the earthquake-based inversions to inversions using the ambient seismic noise field. We will develop interferometric techniques that do not require the traditional assumption of an equipartitioned wavefield, and that allow us to jointly invert for Earth structure and the sources of seismic noise. Furthermore, we will analyze how common noise processing techniques lead to an effective, i.e. distorted, view of Earth structure and noise sources. In the third part we will study how the first and second part maybe combined into a new class of techniques where earthquake and ambient noise data are inverted jointly, instead of following traditional approaches where one is removed from the other.This class will be complemented by small programming examples in order to illustrate basic concepts. Since we will mostly cover ongoing research, this class is also intended to provoke discussions and collaborations.
