Centroid-moment tensor solutions for January-March 1997

Centroid-moment tensor solutions are presented for 162 earthquakes that occurred during the first 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, J.H., 1992. Acoustic imaging at the planetary scale. In: H. Emert, H.-P. Harjes (Eds.), Acoustical Imaging. Plenum, New York, 19, 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 Seismol. Sec. Am., 86, 144-158] is used to predict the decay of the waveforms. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
