Tsunamiites: Features and Implications, Second Edition, is an overview of the state-of-the art developments in sedimentology of tsunami-induced and tsunami-affected deposits, namely tsunamiites. It also highlights new problems and issues calling for additional investigation and provides insight into the direction for future tsunamiite research.

New to this edition: discussion of the impact of 2011 tsunami in Northern Japan as well as additional coverage of offshore tractive current deposition and deposition of boulders.
