Centroid-moment tensor solutions for April-June, 1997

Centroid-moment tensor solutions are presented for 220 earthquakes that occurred during the second 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 Press, Vol. 19, pp. 785-797]. A new 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. Seism. Sec. Am., 86, 144-158] is used to predict the decay of the waveforms. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
