Abstract

The characteristic damping (energy e-folding) time derived from the decay of the tsunami "pulse" can be compared to the dissipation time of the lunar semidiurnal tides as inferred from the discrepancies in the orbital motions of the Moon, Sun, and Mercury. The times are comparable, of the order of ½ day, and this suggests that the same processes are responsible for the dissipation of the tide waves and tidal waves.
