Megablocks are erratic coral boulders, some with dimensions as great as 10 m or more, found in and landward of active reef zones. In locations where they can only have been wave-emplaced, they provide important information about the frequency and intensity of rare, very large storms and tsunamis. However, at present identifying the specific characteristics that constrain the features of the waves that emplaced them, or that confirm their origin to be a storm or tsunami, is still a subject of active research.
