Travel times

How long the first wave took to reach each part of the ocean, one line for each hour up to 24, estimated from the source and the depth of the sea.

The travel times are computed in your browser, which needs JavaScript.

  • 1 to 4 hours
  • 5 to 6 hours
  • 7 to 14 hours
  • 15 hours and more

Computed in your browser the way NOAA’s own travel time maps are: the wave travels at the square root of gravity times the depth, over NOAA’s ETOPO1 depths averaged to a 10 arc-minute grid. Checked against NOAA NCEI’s maps for 21 tsunamis over the first 24 hours, these lines fall within 10 minutes of NCEI’s at half the points compared and within 52 minutes at 9 in 10. They give when the first wave could arrive, not how high it is; bays, harbors and island chains finer than the grid can see it later. Not for use in a warning: see tsunami.gov.

Houses destroyed
Many (101 to 1,000) with the earthquake or eruption that caused it

What the record says

NCEI’s account, from the sources it cites.

In 1783 Calabria (southern Italy) was shaken by the most violent and persistent seismic crisis occurred in the last two thousands years. Third of the five very strong earthquakes occurred in a short interval of time (February-March), causing destruction and a lot of victims in a vast region embracing the whole southern Calabria and the Messina area, Sicily. At Stilo sea rising with no flooding.

Every runup

Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
