West Australian coastlines experienced several tsunamis in mid-Holocene times. To expand our knowledge about Holocene tsunami events in West Australia, the authors extended the previously studied spatial scale to include the central- and south-western coastlines. Several of the discovered events were mid- and young Holocene (≤1000 yr BP) tsunami impacts on the outer coast of the Cape Range Peninsula. Five hundred kilometres to the south between Cape Cuvier and Point Quobba, additional tsunami evidence exists on top of steep cliffs over a coastal stretch of 30 km. The sedimentary signature of two tsunamis is documented in this area by wide …

Along 2500 km of the Western Australian coast, prehistoric ephemeral marine inundations (storm surges or tsunamis) were much larger than those that occurred since European settlement. The evidence is in the form of shell and coral deposits atop 30-m-high headlands, sand deposits containing large boulders, shell and coral several kilometers inland, and fields of large imbricated boulders across shore platforms. The size of transported boulders and the altitude of these deposits suggest that tsunamis were responsible, not large storm waves. The orientation of boulders reveals paleowave directions. Radiocarbon dating of the deposits suggest three very large tsunamis along this coast …
