Centroid-moment tensor solutions are presented for 238 earthquakes that occurred during the fourth 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 [Dziewonski, A.M., Woodward, R.L., 1992. Acoustic imaging at the planetary scale. In: Emert H., Harjes, H.-P. (Eds.), Acoustical Imaging, Plenum, 19, 785–797]. A new model of anelastic attenuation of Durek and Ekström [Durek, J.J., Ekström, G., 1996. A radial model of anelasticity consistent with long-period surface wave attenuation, Bull. Seism. Soc. Am., 86, 144–158] is used to predict the decay of the waveforms.
