Enhancements in earthquake ground motion assessment through regional Vₛ₃₀ characterization and Vₛ₃₀ scaling
… of ground shaking caused by earthquakes. Vₛ₃₀, the time-averaged shear wave velocity in the upper 30m, is a prevalently utilized parameter in numerous predictive ground motion models (GMMs) and building codes to account for site effects. Although the database of in-situ measurements of …

Elasticity across the post-stishovite transition in subducted basalt
Regional seismic studies have found many small-scale scatterers with shear wave velocity (Vₛ) anomalies near subducting slabs in the lower mantle, indicating chemical anomalies at depth. Subducting slabs transport surface hydrated mid-ocean ridge basalt (MORB) into deep Earth, which is chemically …
