Ambient noise attenuation and velocity tomography of Love & Rayleigh
waves applied to the Ramona reservation linear array across the San
Jacinto Fault Zone
Abstract
▪ Our attenuation inversion method is based on Liu et al. (2015) using
linear triplet of stations ▪ Application to the dense 3C linear array
crossing the San Jacinto Fault in Ramona, CA ▪ Clear fundamental mode
Rayleigh and Love wave phases are extracted ▪ Attenuation tomography
maps reveal new information in addition to velocity tomography ▪ Shear
velocity radial anisotropy and possible shear attenuation anisotropy
