GitHubPublished in Earth and Planetary Science Letters (Peer-Reviewed Publication): Seismic Anisotropy in Taiwan
Co-authored a study on near-surface (<500 m) seismic structure across 60 borehole sites in Taiwan, revealing strong anisotropy variations linked to geological units. Orogeny-parallel anisotropy dominates in metamorphic rocks, while stress-aligned anisotropy appears in younger sediments. Published in EPSL.
