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.

Where the literature gives no number, NCEI records a description on a scale of 1 to 4, printed here in its words. Damage is in millions of US dollars of the year of the event, not adjusted for inflation.

What the record says

NCEI’s account, from the sources it cites.

Rockslide of 5000 cubic meters dropped vertically into the fjord Bindalsfjorden at Hildringen near Terråk, Nordland. Upper part released from 110 m a.s.l. The run-up height at the island Øksninga 1.5 Km to the north was more than 2 m at high tide, and caused damage to boat houses and harbours. (reference #4139)

1979 Oct 06, Northern Norway, 65.117 N 12.333 E. Rockslide of 5000 cubic meters dropped vertically into the fjord Bindalsfjorden at Hildringen near Terrak, Nordland. Upper part released from 110 m a.s.l. The run-up height at the island Oksninga 1.5 Km to the north was more than 2 m at high tide, and caused damage to boat houses and harbours (Larsen,, 1979; Maramai et al., 2003). (reference #11164)

Every runup

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