Centroid-moment tensor solutions for October-December, 1999

Centroid-moment tensor solutions are presented for 258 earthquakes that occurred during the fourth quarter of 1999. 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 model of anelastic attenuation of Durek and Ekstrom [Durek, J.J,, Ekstrom, G., 1996. A radial model of anelasticity consistent with long-period surface wave attenuation, Bull. Seismol. Sec. Am., 86, 144-158] is used to predict the decay of the waveforms. (C) 2000 Elsevier Science B.V. All rights reserved.
