Abstract

A microseismic storm recorded at the Harvard Seismograph Station November 14-16, 1945 is analyzed. Associated meteorological conditions are described. Rayleigh waves and Q-waves are identified. Rayleigh waves are used to determine the direction of approach of the microseisms. It is found that the microseisms did not radiate from the center of the barometric low and that at the height of the storm they approached the station from several directions. The position of the cold front associated with the storm correlated better than that of the barometric low with the directions from which microseisms were observed.
