NORSAR or Norwegian Seismic Array was established in 1968 as part of the Norwegian-US agreement for the detection of earthquakes and nuclear explosions.[citation needed][1] NORSAR was the first non-US site included in ARPANET in 1973.[2] 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.[3]

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.[4] NORSAR conducts basic seismological research, develops software and provides consultancy for the petroleum industry.[5]
