Resumen

The elevation of the free surface of a liquid relative to the bottom is calculated for a layer of incompressible heavy liquid with a thickness fo 4 km located over an elastic half-space with a point or distributed centre of expansion acting on it at a depth of 40 km, the intensity of which undergoes stationary transient oscillations. The dependence of this elevation on the period of the source is investigated in the case when the period is greater than 2 minutes but less than 40 minutes. It is established that observable tsunamis are only excited by low frequency oscillations of the source.
