Microseisms associated with the Incidence of the South-west Monsoon

Abstract

THE late Dr. Klotz was the first to suggest a relationship between disturbed weather in the North Atlantic and the largest microseismic movements at Ottawa. The microseisms recorded by the Milne-Shaw seismograph at the Colaba Observatory during the burst of the monsoon on the west coast of the Indian Peninsula present many interesting features and indicate the possibilities of a forecast being made of the approaching monsoon at least a week ahead. The seismograph, which is installed in an underground constant temperature room, gives records remarkably free from microseisms during the cold weather period.
