To ask the Secretary of State for Defence if he will place in the Library a copy of the paper on seismic monitoring by Professor Alan Douglas of his Department's verification centre at Blacknest, given to the seminar on the detection and recognition of underground nuclear explosions held at the Geological Society, London, on 14 February.
I have arranged for a pre-publication copy of the paper given by Professor Alan Douglas at the Geological Society on 14 February to be placed in the Library. This copy consists of the illustrations presented together with an explanatory commentary. A more comprehensive version of the paper is to be published, by the Royal Astronomical Society, in the symposium proceedings which will be available later in the year. When the published proceedings are available a copy will be placed in the Library.
