LARGE-ARRAY SIGNAL AND NOISE ANALYSIS. CORRELATION BETWEEN STORMS AT SEA AND LASA LONG-PERIOD NOISE.
Abstract
Wavenumber and frequency spectra of nine long-period noise samples recorded at the Montana LASA were compared to wave-height charts for the nearest available time. No attempt is made to give a comprehensive explanation of the relationships between seawave activity and long-period seismic noise. A study of these nine noise samples suggests that, in general, the spatial organization of the LASA long-period noise cannot be predicted by examination of wave-height charts. With one exception, strong point-like noise sources generally seem to be associated with areas of high wave activity impinging on a land mass. Strong wave activity in the Pacific Basin not in contact with any land mass does not generate observable long-period noise. Relatively quiet days do not show areas of strong wave activity impinging on land masses. (Author)
