Abstract
THE value of the seismograph as a detector of the more severe type of cyclonic storm in the Bay of Bengal was recognised some fifteen years ago by Mr. C. W. Peake, then Meteorologist at Calcutta. When I left the Observatory in 1922 it had become regular routine for the Omori charts to be examined for microseisms during the writing of the Daily Weather Report, whenever pronounced symptoms of a serious storm existed in the south of the Bay. Well-marked microseisms invariably confirmed other evidence in the case of the early stages of dangerous cyclones, and were sometimes noticed when the storm centre was so much as 1000 miles south of Calcutta.
