Centroid-moment tensor solutions for July–September 1997

Abstract

Centroid-moment tensor solutions are presented for 209 earthquakes that occurred during the third quarter of 1997. The solutions are obtained using corrections for aspherical earth structure represented by a whole mantle shear velocity model SH8/U4L8 of Dziewonski and Woodward [Acoustic imaging at the planetary scale, in: H. Emert, H.-P. Harjes (Eds.), Acoustical Imaging, vol. 19, Plenum Press, New York, pp. 785–797]. A new model of anelastic attenuation of Durek and Ekström [Bull. Seism. Soc. Am. 86 (1996) 144] is used to predict the decay of the waveforms.
