Beskrivning

Microseismic studies involve three main disciplines - oceanography, meteorology and seismology. In her comprehensive treatment of the subject, the author discusses the simultaneous generation of microseisms, oceanic standing waves, infrasound waves, geomagnetic oscillations and the effect of these waves on communication systems. Techniques of locating the sources of excitation are described, together with applications to navigation and wave and weather forecasting.
