An investigation of swell and microseisms from the hurricane of September 13–16, 1946

Date from swell and microseism records associated with the hurricane of September 13–16, 1946 are compared. There appears to be no relationship between the period of the swell arriving at Cuttyhunk off Cape Cod and the period of microseisms recorded at nearby Weston Observatory. Time relationships tend to minimize the importance of swell or resulting surf as the microseism excitation factors. The origin of the microseisms is suggested as occurring directly beneath the storm.
