| Zusammenfassung |
| The Australian megatsunami hypothesis has been developed over two decades. It
charts repeated inundation of the South East Australian coast during the
Holocene by bolide impact megatsunamis. The most enigmatic evidence for these
proposed events are high elevation cliff-top boulders. There is however an
absence of known sources for these megatsunamis, and as such we question
whether the researchers may have the correct mechanism but the wrong events.
Given the low denudation rates of this passive, intraplate environment, we
suggest that boulder emplacement may have been solely the result of the much
older Eltanin asteroid tsunami about 2.5 Ma ago. |
