NORSAR

NORSAR or Norwegian Seismic Array was established in 1968 as part of the Norwegian-US agreement for the detection of earthquakes and nuclear explosions. NORSAR was the first non-US site included in ARPANET in 1973. It was also a connection point for ARPANET to spread to England, and then to the rest of Europe. Since 1999, NORSAR has been an independent research foundation.

Located at Kjeller, north of Oslo, NORSAR runs and maintains seismic arrays in Norway and it is the designated Norwegian National Data Centre for the Comprehensive Nuclear Test Ban Treaty. NORSAR conducts basic seismological research, develops software and provides consultancy for the petroleum industry.
