Identification of Individual Events in a Multiple Explosion from Teleseismic Short Period Body Wave Recordings

The objective of this study is to detect and identify the individual events in a hypothetical multiple explosion. The data analyzed are simulated short period body wave recordings of that event. These were, presumably, constructed by lagging, scaling and summing a single event record according to some formula unknown to the analysts. Data for two stations, including both the single event and multiple event records, were provided to Systems, Science and Software by the VELA Seismological Center (VSC). The data were analyzed by the MARS (Multiple Arrival Recognition System) program which uses a series of narrow-band filters to identify phase arrivals. Their amplitude and arrival time are accurately preserved. The variable frequency magnitude (VFM) discriminant is also computed and the multiple explosion records are clearly identified as being from an explosion. Sponsored in part by DARPA.
