Download or read book Surface Motions from Underground Explosions Appendix A Response Spectrum Analysis of Records from Events Blanca and Logan written by D. S. CARDER and published by . This book was released on 1961 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground effects resulting from certain HARDTACK II underground explosions were measured by strong-motion and teleseismic seismographs from 2000 feet to distances of nearly 100 miles. In addition, many temporary seismographs were operated by a number of organizations to distances of nearly 2400 miles, and routine seismographs continued to operate on a world wide basis. Some of the results are given in this report. An energetic wave believed reflected from the surface near the source was recorded by some of the strong-motion seismographs. It is out of phase with the initial wave and follows it by about a quarter second. From the ground effects standpoint, the Blanca shot was equivalent to a magnitude 4.8 earthquake, and seismic energy contained in a wave 0.8 km. from the source is believed to contain about 0.4 percent of the yield energy. The Logan and Rainier shots were respectively equivalent to magnitude 4.5 and 4.1 earthquakes and corresponding seismic energies contained respectively 0.5 and 0.3 percent of the yield energy.

Book excerpt: Seismic effects of Rainier, a 1.7-kt nuclear shot detonated 900 feet underground, were measured in terms of ground surface motion at ten strong-motion seismograph stations located 1200 to 45,000 feet from the source. In addition, records were borrowed from seven teleseismic stations located 100 to 300 miles from the source. Recorded accelerations attenuated from a maximum singlecomponent value of 2.6 g at 1280 feet to 0.009 g at 17,640 feet. Gutenberg-Richter magnitude of Rainier, calculated as for a natural earthquake from seven WoodAnderson seismograph records, was 4.6. Earthquakes of 4.6 magnitude are felt up to 60 miles from the epicenter, however, Rainier was felt by only a few observers at 21/2 miles. Seismologists at established teleseismic stations were able to pick out Rainier's elastic wave signature on seismograms at considerable distance. Very small amplitude waves from Rainier were found on the Coast and Geodetic Survey, College, Alaska, seismogram, 3600 km away, although attempts in the eastern United States at distances of 2000 to 3000 km, using conventional instruments, were not successful.
