Page 109 - The number of control posts; (c) The probability of correct identification of natural events, particularly earthquakes. The dependence between these parameters is such that with an increase in the yield of the explosion or the number of control posts the probability of detection and identification increases, and the number of unidentified events suspected of being a nuclear explosion decreases. On the other hand, for the identification of the increased number of unidentified events resulting from...
Page 627 - ... to establish the approximate time and position of the event. This requires at least four clearly measurable arrival times of identifiable phases which are mutually consistent to within plus or minus three seconds.
Page 651 - ... expanded to include facilities for testing other detection methods proposed by this Panel or methods which may be developed through future research programs. A high priority should be given to testing arrays of up to 100 seismometers and testing a system of unmanned auxiliary stations. For maximum effectiveness, the station should be installed in a seismic region where the data collected would assist in more general research problems. Finally, research should be stimulated to develop new methods...

Page 629 - First motions recorded at distances between 1100 kilometers and 2500 kilometers will not be used. First motions beyond 3500 kilometers will not be used for events of magnitude smaller than 5.5. The apparent direction of first motion must also meet both the following minimum conditions to be considered to be clearly recorded : (1) The amplitude of the...
Page 627 - This requires at least 4 clearly measurable arrival times of identifiable phases which are mutually consistent to within ±3 seconds. These 4 consistent arrival times must include P-wave arrival times at 3 different control posts. If the event is eligible for inspection, the area eligible for inspection consists of that 500 square kilometers which has the highest likelihood of containing the epicenter, according to a previously established data reduction procedure. This procedure shall take into...
Page 647 - More detailed analysis of smaller regions may be obtained from seismic sounding with the shorter period waves generated by explosions (10). The outstanding work in this particular field has been done by the USSR , because of the large effort which has been made in comparison to that of the US Sufficient talent and instrumentation are available in the US to match and surpass this Soviet effort and at the same time to exploit a major tool for exploration of the solid earth. A program of crustal exploration...
Page 597 - ... identification of earthquakes. The measurement of long-period waves would be facilitated by including, at all control posts, three-component long-period seismographs with response characteristics optimized for the registration of such waves. These waves will have periods greater than about 10 seconds. 3. Improvement of the operating characteristics of seismic equipment It may be possible to develop seismographs with more nearly ideal response characteristics, both in the region of long and short...
