The detection and discrimination of seismic events
while monitoring for small nuclear explosions is complicated by a significant
amount of commercial mining explosions. Although
mining explosion databases have been constructed to help with this problem in
various regions of the world, very little is known about the contribution of
mining activity in southern Asia to the regional seismicity.
This project will build an extensive ground truth database for southern
Asia that includes well-located mining explosions and earthquakes, using data
currently being collected in the region along with location algorithms and
velocity models currently in development.
Phase I will combine previously published mining explosion data from
various mining regions in southern Asia with new data being collected in the
region into a format-consistent database for use by the United States nuclear
explosion monitoring community. Various
methods will be employed to separate commercial mining explosions from the
extensive natural seismicity of the region.
The ground truth classification of the mining explosions will then be
determined.
Commercial Applications And Other Benefits as described by awardee: The ground truth database should allow for improved seismic event discrimination and improved seismic event location in southern Asia.
