This report summarizes progress which has been achieved during the past year in the development of a comprehensive new seismic yield estimation system (YES) for underground nuclear explosions. Specifically, a prototype version of YES which is applicable to explosions at the Soviet Shagan River and Novaya Zemlya test sites is described in detail. In its current configuration, the YES encompasses a database of more than 10,000 digital seismograms recorded at stations of the USAEDS, GDSN, CDSN and IRIS networks from explosions at these two test sites. For both test areas, information regarding the explosion source environment is presented to the analyst in the context of SPOT (tm) satellite images of the sites, together with associated surface and subsurface geologic information and DMA topographic data. The on-line database for YES also contains a wide variety of tabular information including complete event and station location files containing both classified and unclassified locations, standard travel-time tables for the seismic arrivals used for yield estimation, propagation path and station corrections for use in magnitude determinations and a comprehensive instrument response database. The capabilities and functionality of the current version of the YES system are graphically illustrated in Section 2 using displays of the screens encountered by an analyst in a typical processing session.
