Montana Large Aperture Seismic Array.

Abstract

The report concerns technical activity at the Montana Large Aperture Seismic Array(LASA). IBM System/360 Model 44 computer programming to complete the Montana segment of the Interim Integrated Signal Processing System (IISPS) and system testing are discussed. Array work described includes installation of attenuated short-period and long-period seismic signal channels and completion of the Large Aperture Microbarograph Array (LAMA). A report on the experiment which utilized the LASA for early warning of the occurrence of potentially destructive earthquakes concludes that the reaction time for reporting large event parameters is on the order of one-half hour and that currently employed LASA data analysis techniques are adequate.
