A Global Centroid Catalog of S‐Wave Microseisms: Insights Into the Role of Sedimentary Layers
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.Abstract Although centroid catalogs of P‐wave microseisms have been established, a corresponding centroid catalog of S‐wave sources has been lacking. In this study, we constructed a centroid catalog of S‐wave microseisms. We generalized the autofocusing method to radial and transverse components to estimate the source locations of SV‐ and SH‐wave ...
