The Broadcasting of Seismological Reports

Abstract

FROM the records of a single well-equipped observatory the position of the epicentre of a large earthquake at a great distance can normally be determined with considerable accuracy. Closer estimates can be made, however, when the records from several stations are available, and especially when the stations are well distributed over the world. A system of exchange of seismological information by cable was inaugurated several years ago by the British Association. By the use of information received from stations in India, Australia, and America, Prof. H. H. Turner, chairman of the British Association Seismological Committee, has been able to determine the details which he has communicated regularly to the Press.
