Abstract : We have been developing four specific technology areas that could be used during on-site inspections under a comprehensive test ban treaty: aftershock monitoring, noble gas monitoring, electromagnetic pulse monitoring, and overhead imagery detection of disturbed ground. Our investigation of aftershocks has shown that the low-frequency aftershocks that have been observed after nuclear tests at the Nevada Test Site are also associated with certain kinds of mining operations such as block caving. Our noble gas detection effort has successfully predicted the travel time of two tracer gases emplaced in the Non-Proliferation Experiment. Our EMP effort has developed a stand-off relationship for EMP sensors from the source and to date, has found that mining explosions do not generate significant low-frequency EMP. Our overhead imagery effort suggests that plant stress from shocked ground above an underground explosion may be detected using a ratio of 690 to 420 microns of visible light
