Research on Seismic Monitoring at Regional Distances 15 OCT 96 87 pages
Authors:  Wenjie Dong; Richard L. Gibson Jr.; Matthias G. Imhof; M. N. Toksoez; MASSACHUSETTS INST OF TECH CAMBRIDGE EARTH RESOURCES LAB
The full text of this report is available for sale.We report two studies related to numerical modeling of seismic wave generation and propagation. In the first, numerical calculations of seismic wave scattering using the multiple multipole technique are compared to laboratory data that we collected in an ultrasonic experiment. The results demonstrate the validity of the multiple multipole approach for seismic wave propagation modeling. The second study investigates seismic radiation from explosively loaded cavities in isotropic and transversely isotropic ...


Basic Research in Nuclear Test Monitoring: Explosions in Non-Spherical Cavities: Investigations of Enhanced Backscattering 01 JAN 94 103 pages
Authors:  Batakrishna Mandal; Craig A. Schultz; Wenjie Dong; M. N. Toksoez; William Rodi; MASSACHUSETTS INST OF TECH CAMBRIDGE EARTH RESOURCES LAB
The full text of this report is available for sale.We report on two studies. The first is a theoretical study of the seismic radiation from explosions detonated in finite cylindrical tunnels embedded in a homogeneous, isotropic, elastic medium. We developed a frequency domain boundary element/discrete wavenumber algorithm to model the seismic wavefields from such sources, and applied the algorithm to study two specific cases of explosion sources-nuclear and non-nuclear. Our calculations show different source radiation patterns between the two ...
