Title

Data and codes to demonstrate measurement of shear-wave attenuation anisotropy beneath the Ethiopian Rift

Abstract

Shear-wave attenuation anisotropy can provide constraints on mantle melt, such as that present beneath the Ethiopian rift. This package contains codes implementing a new methodology to measure such attenuation anisotropy, as well as a suite of synthetic data to demonstrate its utility. This method has been applied to SKS phases recorded over a decade at seismic station FURI in Ethiopia. The package provides these data, and the resulting derived measurements. The study, and the material provided here, are described in Asplet et al 2024 "Shear-wave attenuation anisotropy: a new constraint on mantle melt near the Main Ethiopia Rift" which is accepted for publication in Seismica.
