摘要: [1] Microseismic vibrations during the famous October 1991 “Perfect Storm” were observed at seismic stations across North America. The extreme wave conditions this storm, in conjunction with occurrence of Hurricane Grace to south, are ideal for studying where such originate and their inland propagation. High-amplitude primary double-frequency (DF) microseisms broadband station HRV eastern Massachusetts. Similar spectral variation ANMO Albuquerque, New Mexico, shows transcontinental propagation from Perfect Storm. Cross correlation between spectra widely separated buoy measurements corresponding DF microseism give high-correlation coefficients, R2, England coast Cape Hatteras. Contours peak R2 scaled by magnitude lag peak, together similarities variation, imply that dominant source area Storm is near southern Massachusetts coast, not open ocean highest waves occurred.
