A tsunami caused by an earthquake began at N. Luzon Island, Philippines in 1744. Its effects were recorded at 1 place.
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.

What the record says
NCEI’s account, from the sources it cites.
Reference #414:
1744. In the northern part of Luzon Island there were earthquakes which affected a vast area and lasted several months. The sea entered the river with great force.
Reference #1187:
1744. Northern Luzon: There were widespread earthquakes which lasted for whole months. The sea enters the river with great force.
Reference #3029:
1744. Northern Luzon. In the Diccionario Ibanag-Espanol there is mention of earthquakes under the word ALLUYU, meaning great waves, as follows: "The sea enters the
river with great force ... as happened ... in the year 1744, there were widespread earthquakes which lasted for whole months." JB, p. 20.
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
