Rayleigh‐Love Discrepancy Highlights Temporal Changes in Near‐Surface Radial Anisotropy After the 2004 Great Sumatra Earthquake

Abstract

Takagi et al., 2012), are uniquely effective in probing changes in the seismic wave speed of the uppermost few kilometers of the crust. Previous analyses have shown substantial velocity changes (several percent) in the near-surface layer, likely induced by the strong ground motions of great earthquakes (
