Book Description
Brief summaries of work currently underway or recently completed are given in four study topic areas: Source, Data Analysis, Surface Wave, and Body Wave. The remainder of the report presents research results not previously reported: (1) Discrimination Experiment--Digital short- and long-period body and surface wave data for Eurasian events recorded at a global network of stations are being provided for event discrimination. Efforts have focused on application of the VFM (Variable Frequency Magnitude) discriminant to the short period P waves at four stations; (2) Analytic Continuation of the Elastic Field from a Complex Source in a Halfspace. This section presents the mathematical development of a method for linking finite difference numerical source calculations in a halfspace with analytical techniques for propagating elastic waves in layered media; (3) Theoretical Computation of Lg--This discussion is concerned with the theoretical generation of Lg in a continental earth model. Synthetic seismograms are shown for several ranges and source depths, and (4) Analysis of Surface Waves from the French Test Site in the Sahara.

Book Description
The subject of this NATO Advanced Study Institute was seismic monitoring under a nuclear test ban - an application of scienti fic knowledge and modern technology for a political purpose. The international political objective of a comprehensive nuclear test ban provided in turn the motivation for our technical and scientific discussions. In order to obtain a historical perspec tive on the progress of the work towards a comprehensive test-ban treaty (CTB), it is necessary to go back to 1958, when a confer ence of scientific experts in Geneva made the first steps toward an international seismic monitoring system. However, agreement on actual capabilities of a monitoring system for verifying compliance with such a treaty was not achieved, and thus the conference did not lead to immediate political results. After the Partial Test Ban Treaty of 1963, which banned nuclear explosions in the atmosphere, outer space and under the seas, renewed interest in the seismological verification of a CTB took place. A number of countries initiated large-scale research efforts toward detecting and identifying underground nuclear explosions, and it was in this context that the large aperture seismic arrays NORSAR and LASA were established. This type of development resulted in excellent seismic data in digital form and was thus of great irnprotance to the seismological com munity.
