Correlation measurements of Atmospheric Pressure variations and Seismicity during Hurricane Dennis

During the passage of hurricane Dennis, two functionally different instruments made continuous recordings from their location in Macon, Georgia. These were (i) a non-conventional vertical seismometer, and (ii) a low-level differential pressure sensor. Data were collected for 72 hours, beginning when the eye of the storm was located in the vicinity of Key West, Florida. Over the ensuing three-day period, fluctuations in the outputs from the two instruments were found to be highly correlated, with the exception of one eight hour interval.
