摘要: A study of wave radiation by a piston bottom displacement, in compressible ocean constant depth, is carried out within the framework two-dimensional linear theory. Simple analytic expressions for flow field, at large distance from disturbance, are derived. realistic numerical example indicates that Acoustic-Gravity waves, which significantly precede tsunami, expected to leave significant signature on bottom-pressure records should be considered early detection tsunamis.
