What you see

  • Tsunamis alone, as natural-hazard marks at their source; History’s panel can add the quakes and eruptions that raised them.
  • Click one for the deaths, the highest water and the number of places where the water was measured.
  • Opened from this page, the map plays 1800 to today.

Where the data comes from

  • NOAA NCEIThe Global Historical Tsunami Database, with the runups observed for each event.

NOAA adds tsunamis as it reviews them; TAKIP takes them when the set is imported again.

Good to know

  • About one in four records any deaths.
  • Japan alone holds about one in seven.
  • About 400 are from before 1800, known from written accounts.
  • The Wikipedia article, where there is one, is usually the earthquake’s.
