The Norwegian Seismic Array (NORSAR). Phase 3
Abstract
This report describes the operation and research activities at the Norwegian Seismic Array (NORSAR) for the time period from 1 April to 30 September 1978. In general, the array operation is characterized as stable, with little change from the previous reporting period. There has been a slight improvement in the performance of the data recording and online detection processing relative to the previous reporting period (uptime increased to 93.7% from 91.6%). The Special Processing System (SPS) is still the major cause of the breaks in operation (75 out of 139), the longest one lasting for more than 4 days. Statistics from short sample intervals indicate that the number of Online detections average about 200 per day with the present threshold setting, while the On-line Event Processor processes about 25 events per day for transmission to the SDAC. The average number of analyst-retrieved and accepted events has been 10.8 per day during the period.
