Centennial: The Anisotropic Earth
Session ID#: 79531
Session Description:
Seismic anisotropy has proven to be a vital constraint in characterizing the dynamic and tectonic processes that have shaped the Earth. Because of the fundamental importance in fully characterizing the amount and orientation of anisotropy as it relates to dynamic processes, numerous seismic analysis techniques have been developed and implemented. Significant work in laboratory experiments has helped illuminate the relationship between deformation, mineralogy, and seismic anisotropy. This session aims to highlight the modern advances made in the application and methodology of the analysis of seismic anisotropy as a tool to better understand our planet by highlighting advancements in seismological techniques from full-waveform modeling, receiver functions, shear wave splitting, surface waves, normal modes, and more. We encourage contributions spanning all depths from the inner core to the crust. We will look back at the field of seismic anisotropy as well as consider the future by emphasizing novel methods and modern advancements.
