Abstract:

Deep-well seismic data recorded at UBO in SeptemberOctober 1964 are used to estimate the capabilities of three 3-element vertical arrays and one hypothetical 6-element vertical array. The application of deconvolution and autocorrelation techniques to three ensembles of earthquake records from the multichannel processor at CPO is being studied. Statistics of discrepancies between observed and USC and GS reported origin times, magnitudes and depths of focus are examined. A description of the mathematical operations and computer programs required to perform probabilistic processing is given. Four multichannel filter systems for CPO were designed using the full array and three partial arrays. Information concerning the recording and preliminary processing and analysis of a 20-min ambient seismic noise sample from the ring array, the large cross array and a 3-component seismometer at Tonto Forest Seismological Observatory is given.
