Comparative analysis of the seismic characteristics of cavity decoupled nuclear and chemical explosions. Final report, 1 November 1992-31 October 1994
Successful seismic monitoring of any eventual Comprehensive Test Ban Treaty will require the development of a capability to identify signals from small cavity decoupled nuclear explosions from among the numerous signals to be expected from earthquakes, rockbursts, and chemical explosion (CE) events of comparable magnitude. The investigations summarized in this report center on a variety of comparative analyses of observed and simulated seismic data corresponding to decoupled nuclear explosions with data recorded from both tamped and near-surface, ripple-fired CE events. More specifically, seismic data recorded from cavity decoupled nuclear tests in both the U.S. and former Soviet Union are used to assess the relative seismic coupling efficiencies of the different types of CE events and to evaluate potential seismic discriminants which might be used to identify the various source types. The results of these comparison studies indicate that tamped CE events with yields on the order of 7 tons and ripple fired CE events with yields in the 70-100 ton range can be expected to produce near-regional ground motion levels comparable to those expected from fully decoupled 1 kt nuclear explosions at Azgir.
