Montana Large Aperture Seismic Array

Abstract

The technical activity associated with the operation, maintenance, and improvement of the Montana Large Aperture Seismic Array (LASA) during the period 1 December 71 - 30 June 73 is related in this report. The short-period (SP) and long-period (LP) seismograph sensitivity performance statistics are indicated. The measured free period and mass position characteristics for the LP seismometer array are presented. Development of pseudo-random binary sequence (PRBS) calibration technique for the remote measurement of the amplitude, phase, and sensitivity characteristics of the LP seismograph over a broad band of frequencies is reported. Improvement to the PRBS calibrations recently developed for the SP seismograph is described. Statistics relating to the operation and maintenance of the array and data center equipment and land facilities support are provided.
