This Semiannual Technical Summary describes the operation, maintenance and research activities at the Norwegian Seismic Array (NORSAR), the Norwegian Regional Seismic Array (NORESS) and the Arctic Regional Seismic Array (ARCESS) for the period 1 April - 30 September 1992. Statistics are also presented for additional seismic stations, which through cooperative agreements with institutions in the host countries provide continuous data to the NORSAR data Processing Center (NPDC). These stations comprise the Finnish Experimental Seismic Array (FINESA), the German Experimental Seismic Array (GERESS), and two 3-component stations in Poland: Ksiaz and Stary Folwark. This Semiannual Report also presents statistics from operation of the Intelligent Monitoring System (IMS). The IMS has been operated in an experimental mode, and the performance has been very satisfactory. Since October 1991, a new version of the IMS that accepts data from an arbitrary number of arrays and single 3-component stations has been operated. NORSAR, Norwegian seismic array Original contains color plates: All DTIC/NTIS reproductions will be in black and white.
