摘要：This paper reviews the various problems of research on microseisms, and also the method of obtaining seismograms. Direction finding techniques are outlined, and possible origins of microseisms are suggested. The surf and wind theory of microseisms are compared. Mention is also made of some recent theories of microseisms. The paper shows how the subject of microseisms is closely connected with that of swell and storm prediction, a problem of interest to Defence Scientists and Meteorologists.
