November 15, 2014 Tsunami: N. Moluccas Islands, Indonesia
A tsunami caused by a magnitude 7.1 earthquake began at N. Moluccas Islands, Indonesia on November 15, 2014 at 02:31:41 UTC. The water rose as high as 0.09 meters. Its effects were recorded at 3 places.
Where the waves reached
The source (white) and every runup with a place, colored by the water height recorded there. A ring is a runup NCEI marks doubtful.
- Under 1 m
- 1 to 3 m
- 3 to 10 m
- 10 to 30 m
- 30 m and more
- Height not recorded
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.
Tsunami waves nine centimetres high were detected at Jailolo on Halmahera island, in the Maluku Islands, the meteorological agency said. Tiny waves were also detected in Tobelo on Halmahera, and in Manado, on nearby Sulawesi island. (reference #11132)
A tsunami was detected in Jailolo, measuring 9 cm, and in Manado, measuring 4 cm (reference #14350)
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
| Where | Country | Km from source | Water height, m | Inland, m | Measured by | First wave, UTC | Deaths |
|---|---|---|---|---|---|---|---|
| Jailolo, Halmahera | Indonesia | 140 | 0.09 | Tide gauge (half the maximum wave height) | |||
| Tobelo, Halmahera | Indonesia | 167 | 0.02 | Tide gauge (half the maximum wave height) | |||
| Manado, Sulawesi Island | Indonesia | 193 | 0.04 | Tide gauge (half the maximum wave height) |
