RESEARCH AND DEVELOPMENT STUDIES UNDER THE VELA UNIFORM PROGRAM, 1959-61 Project Title: Seismic Waves of Long and Intermediate Periods Name of sponsoring Federal agency: ARPA (via AFCRL). Amount and duration of support: $400,000 (2 years). Date of contract: August 1, 1960. Contract expiration date: July 31, 1962. Brief summary of the project: Investigation of the applicability to intermediate and long period seismic waves of phase compensation techniques for the purpose of determining an effective source polarity as a function of azimuth, the development of high-speed computational techniques and the development of seismic instrumentation with increased sensitivity in the long period range and with improved discrimination against noise in the dominant microseism band. Project title: Body Wave Polarity Studies Name of sponsoring Federal agency: ARPA (via AFCRL). Date of contract: July 1, 1960. Contract expiration date: June 30, 1962. Brief summary of the project: Digitalization of seismograms from nuclear explosions and natural earthquakes for subsequent application of numerical analysis techniques, determination of optimum numerical operators for the discrimination of the directional patterns of sources with particular reference to the body wave phases of the seismic record, and conduct study of microseismic noise structure to determine the extent to which its dynamic properties can be used to design optimum linear or nonlinear noise removal filter systems. Project title: Model Studies of Seismic Energy Distribution Name of sponsoring Federal agency: ARPA (via AFCRL). Name of organization: Pennsylvania State University. Amount and duration of support: $18,893 (2 years). Date of contract: September 1, 1960. Contract expiration date: August 31, 1962. Brief summary of the project: Investigation of the radiation pattern of compressional and shear waves from simulated explosive and faulting sources by means of two-dimensional modeling techniques, and investigation of changes in the radiation patterns produced by inhomogeneities in the model medium simulating large-scale inhomogeneities in the earth's structure. Project title: Phase Vélocity and Source Determination Studies Name of sponsoring Federal agency: ARPA (via AFCRL). Amount and duration of support: $284,084 (3 years). Contract expiration date: July 31, 1963. Brief summary of the project: Investigation of the phase velocity versus frequency relationship for long-period surface waves by means of a quadrilateral network of seismic stations to be established in the midcontinent region with station intervals of 300 to 400 miles, investigation of P-wave and S-wave amplitude ratios and polarities as related to the mechanism and orientation of faulting sources, investigation of Love and Rayleigh wave amplitudes as related to the mechanical characteristics of the source, and study the mechanism of a few selected earthquakes by applying all methods of analysis (P, S, and surface wave) using data from the standardized worldwide network. Project title: SH-type Waves Generated by Small Explosions Name of sponsoring Federal agency : ARPA (via AFCRL). Amount and duration of support: $31,787 (3 years). Date of contract: August 1, 1960. Contract expiration date: July 31, 1963. Brief summary of the project: Investigation by means of small explosive charges of the environmental conditions under which horizontally polarized shear (SH) waves may be generated by explosions and investigate the extent to which it is possible to control the distribution of amplitudes of seismic waves around an explosive source by introducing various types of asymmetry at the source. Project title: Research Toward Direction of Motion at Earthquake Focus Name of sponsoring Federal agency: ARPA (via AFCRL). Name of organization: St. Louis University. Amount and duration of support: $6,950 (1 year). Date of contract: February 1, 1961, Contract expiration date: January 31, 1962. Brief summary of the project: Study of the question of single couple versus double couple (or any type of source) as the model of an earthquake focus and verify the existence or nonexistence of a single force type earthquake focus. Project title: Analysis and Reduction of Data Recorded under Project COWBOY Name of sponsoring Federal agency: ARPA (via AFCRL). Name of organization: Texas Instruments, Inc. Amount and duration of support: $5,581 (2 months). Date of contract: March 1, 1961. Contract expiration date: April 30, 1961. Brief summary of the project: Analysis and reduction of data recorded under Project Cowboy by Texas Instruments, Inc. Frequency amplitude spectra will be obtained for pulses before and after decoupling and plots will be made of apparent wavelength versus frequency and frequency versus decoupling factor. Project title: Research Directed Toward a Feasibility Study on the Determination of Depth of a Seismic Energy Source Name of sponsoring Federal agency: ARPA (via AFCRL). Amount and duration of support: $230,000 (2 years). Date of contract: February 15, 1961. Contract expiration date: February 14, 1963. Brief summary of project: An extensive family of surface response curves (motion versus time) are being computed as a function of source depth, detector offset, and a series of simple geological models. The improvement of time resolution of closely spaced or overlapping seismic arrivals of direct and surfacereflected waves from various depths of seismic sources is to be studied by conducting research in the application of inverse filtering to the problem. 74094--61-20 |
