Title: Crustal and Upper Mantle Seismic Anisotropy Across Alaska and the Juan de Fuca Plate from Surface Wave Observations
Abstract: As one of the world’s most tectonically active convergent regions, Alaska and the Aleutian subduction zone have experienced a wide range of past and present-day tectonic processes. Within the continent, tectonic features deep within the lithosphere are invisible at the surface but can be revealed through observations of seismic anisotropy. In the case of the oceanic plate and subduction zone, seismic anisotropy can help us understand the physical properties of plate and directions of mantle flow. In this talk, I will discuss the depth variation of seismic anisotropy and its implications for deep crustal deformation in the Alaskan continent and explore the depth-dependent azimuthal anisotropy features beneath the Aleutian subduction zone and the Juan de Fuca plate.
