| Zusammenfassung |
| Rapid co-seismic bottom displacements during strong submarine earthquake
give rise to intensive low-frequency elastic oscillations of water layer.
Nonlinear energy transfer from the elastic oscillations to long
gravitational waves may provide an additional contribution to tsunami. The
nonlinear tsunami generation mechanism is examined analytically. Finiteness
of bottom elasticity is taken into account. General parameters responsible
for amplitude and energy of the nonlinear contribution to tsunami wave are
revealed. |
