NORSAR (NORWEGIAN SEISMIC ARRAY), PHASE 1 (INSTALLATION)

Abstract

The report concerns installation of Phase 1 of a large aperture seismic array (NORSAR) being built in south-eastern Norway. Phase 1 comprises a 12 short period (SP) seismometers subarray at Oyer near the town of Lillehammer, a 5-7 SP sensors experimental noise study array at Falldalen, E of Lake Mjosa, and a rudimentary long period (LP) array consisting of 3 three-component LP sensors located at Oyer, Falldalen and Borgseter, the latter point situated about 20 km from the Swedish border. The data handling system consists of 5 recording units, one each for the two SP arrays and the three LP installations. Subsequent to a brief pre-history of NORSAR, Phase 1, the report describes the planning and implementation stages and presents the technical data of the project.
