Five SDCS systems which had been deployed in early 1975 continued routine operations throughout the report period. Sites at Red Lake, Ontario, and Whitehorse Yukon, are standard SDCS units; the site at Cumberland Plateau Observatory in Tennessee uses that station's SP array as its SP input. The Franklin, West Virginia, and Houlton, Maine sites use a Model 36000 Borehole Seismometer System. The five stations have routinely collected seismic data on a continuous basis throughout this period. Data analysis tasks for the program are being done at the SDAC in Alexandria, Virginia. During the period, 33 requests for event reports were received and all but 4 had been completed by the end of the period. In addition, a backlog of about 20 reports from the previous period was completed. The last two of five digital data acquisition systems were installed during this period and operation of these systems has been incorporated into the normal SDCS routine with minimum difficulty.
