Seismic attenuation in the Anahim Volcanic Belt and adjacent regions of British Columbia / A.M. Farahbod and J.F. Cassidy. : M183-2/8030E-PDF

"In this study we investigated coda-wave attenuation (Qc) in the interior of British Columbia, with a focus on the Anahim Volcanic Belt (AVB) and specifically the Nazko Cone region using the single scattering approximation on records from short period and broadband stations of the regional Canadian National Seismic Network (CNSN) and POLARIS Network. Our dataset is comprised of 380 earthquakes recorded between 1999 and 2012 with magnitudes ranging from 1.6 to 3.9, depths from 0 to 36 km and epicentral distances of 15 to 100 km. This gives a total of 423 high signal to noise (S/N) traces (S/N≥5.0) useful for Qc calculation (with a range of ellipse parameter, a2, of 30 to 110) across the region"--Abstract, page 4.
