Abstract

The tsunami hypothesis proposes that prehistoric tsunamis may have been larger than historic ones along coasts normally (historically) not associated with major tsunamis. The evidence for the hypothesis rests with the types of unusual sedimentary deposits and erosional forms along coasts where the largest historic and prehistoric storm waves do not appear capable of forming the features. This is especially the case at locations where boundary conditions, i.e. offshore water depth, coastal geomorphology and meteorological limitations, are not conducive to the propagation of sufficiently large storm waves at the shore. The tsunami hypothesis has been barely debated in the literature. This is despite the view of some, who suggest that storms have been overlooked, or underestimated, as a cause. Few comparisons have been made of the supposed tsunami generated features and the impacts on coasts of extreme intensity storms. Four of the most powerful tropical cyclones anywhere in the world in recent times struck the Western Australian coast between 1999 and 2002. The results of post-event surveys of these storms showed that none of them produced the enigmatic forms attributed elsewhere to tsunamis.
