For interest here is a rock on Tongatupu which scientists say is a part of a tsunami debris field.
Cant see it myself although I have been to Easter Island and saw very large stones which had been moved by tsunami. However Maui's rock in Tonga is very large.
It is very close to the sea though.[flic.kr]
