Tsunamis leave their mark in historical, archaeological and geological records with varying levels of completeness. With many of these records there are also problems of distortion and ambiguity, both with respect to the magnitudes of the tsunamis and their exact sources. It is also possible in some cases to identify the source events independently of the evidence for the tsunamis, but in other cases, most notably entirely submarine earthquakes and deep water impact events, the evidence for the tsunamis may be the only mark left by the causative event. Analyses of the regional and global distributions of tsunamis should therefore take account of the limitations of these different types of record.
