Leading seismologists from ten countries including four nuclear powers present a fresh assessment of the state of the art of seismic detection and identification of underground nuclear explosions, a subject of importance for any future negotiation of a comprehensive test ban.
In the United Nations' General Assembly, a summary of the report was welcomed and praised by the delegates of many nations.
