Oceanic Lithosphere: perspectives from Love wave phase velocity

Abstract

Global Love wave phase velocity variations are constructed for periods between 80 and 200 seconds by using approximately 9,000 paths from 971 events (with M ≥ 5.5). The block parameterization approach (5° X 5° near equator) is used in this study. With improved resolution of about 1000 km, we attempt to study the oceanic lithosphere structure by using these results, because they are very sensitive to structure variation in the upper 200 km near the surface.
