Deadliest Tsunamis

This is an evolving table. Records of tsunami deaths are very commonly mixed with earthquake deaths, so notable tsunami events are surely missing from this table, and some numbers here may include deaths not caused by tsunamis. There also have been catastrophic waves recorded in India, attributed to storm surges, that may be tsunamis. The table reflects official compilations and has not been checked in detail. All large round numbers are approximate.
