Deployment of a regional array in Norway

Abstract : The purpose of the development of an experimental reginal array in Norway is to take advantage of the extremely good propagation of high-frequency energy for regional seismic phases in Eurasia. The actual field work has been started with the deployment of the seismic vaults and feilling of two boreholes for seismometers. A central terminal building was completed. Trenching and cable laying was to start implementing the seismic system until completion of system deployment. The work related to transmission of data from the new aray to various locations in the US via satellite and to the NORSAR Data Processing Center was installed and continuous recording of NORESS data was started at Kjeller.
