Seismic Data Analysis Center Quarterly Technical Summary Report, October-December 1974

Abstract

The report summarizes the scientific work accomplished at the Seismic Data Analysis Center (SDAC) in the period October through December 1974. During the quarter, eight technical reports covering six subjects were approved for distribution to the government approved list. Three of the reports (TR-74-16, 17, and 18) describe the programming and processing experience with the ILLIAC IV computing system, while Report TR-74-4 describes a new source theory for complex earthquakes. Two reports are comparative in nature: The first, TR-74-5 compares LASA's Detection Processing System with that of NORSAR's; the second, TR-74-6 is an empirical comparison of the two-segment maximum likelihood frequency-wavenumber (f-k) spectra with the f-k spectra produced by beamforming in the frequency domain. Studies of average P and PKP codas and of an iterative beam processor are documented in Reports 305 and TR-73-7, respectively.
