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."
