The frequency dependence and locations of short-period microseisms generated in the Southern Ocean and West Pacific
The origin of the microseismic wavefield is associated with deep ocean and coastal regions where, under certain conditions, ocean waves can excite seismic waves that propagate as surface and body waves. Given that the characteristics of seismic signals generally vary with frequency, here we explore the frequency- and azimuth-dependent properties of microseisms recorded at a medium aperture (25 km) array in Australia. We examine the frequency-dependent properties of the wavefield, and its...[Show more]
