Bibliography of Seismology

Abstract

THE Bibliography of Seismology, 13, Nos. 14 and 15, Items 5564 to 5787, July 1943–June 1944, published by the Dominion Observatory, Ottawa, Canada, have just been received. In them are listed in full, occasionally with comments, papers and books from all parts of the world except Germany and Japan, dealing with pure and applied seismology. An interesting article listed in No. 14 is item 5579 by Centano-Grau, M., "Estudios sismologicos", Litografia del Comercio, pp. 555, 2 maps, 5 tab., Caracas, 1940, which gives a comprehensive review of many phases of seismology, and puts forward a theory of electrical causes for earthquakes of volcanic origin. The book contains a complete catalogue of earthquakes of Venezuela, and a study of the destructive shocks, including predictions of probable recurrences in different regions. In Nos. 14 and 15 numerous papers are listed dealing with rock bursts, chiefly in Canada and South Africa. One important paper is by Ernest A. Hodgson, "What is a Rock Burst?" published by the Northern News, Kirkland Lake, September 9, 1943, after a radio talk by the author. Other papers are by J. Spalding and include such topics as "Description of a Rock Burst", "Theory and Practice of Ground Control", and "Theory of Rock-Pressure" (Kolar Gold Fields Mining and Metallurgical Society Bulletins, 8, No. 41, 153, Johannesburg, 1935–37). An interesting theoretical topic is listed as item 5709 in No. 15: Finch, R. H., "The seismic prelude to the 1942 Eruption of Mauna Loa" (Bulletin Seismological Society of America, 33, No. 4, 237; 1943). The paper presents evidence that the eruptions of Mauna Loa are preceded by pronounced seismic activity, but that this activity falls off for a month or more prior to the actual eruption. This paper may be considered a sequel to Harry O. Wood's paper in the same journal in 1915 on the 1914 activity. Items from Nature are listed in both parts of the bibliography.
