Seismic Discrimination
Abstract
New short-period data on source functions both of explosions and earthquakes are reported. Studies of wave propagation in inhomogeneous regions of the earth are described. First results from NORSAR are presented. Long- period noise and signal observations have been made, and some idea of NORSAR's discriminative capability is emerging. Network approaches to discrimination are being expanded. Major improvements in P-wave detection capability are in sight, with joint array and network analysis. New programs are being applied to the rapid acquisition of library information on seismic events. An increasing use of LASA for other geophysics projects is apparent.
