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.

The toll

Damage
Limited (under about $1 million) with the earthquake or eruption that caused it
Houses damaged
Few (about 1 to 50) with the earthquake or eruption that caused it

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.

Reference #414:

1828, November 9, 18:30 [local time]. There was an earthquake at Manila in the form of long-period regular oscillations, lasting 2 or 3 minutes, which appeared to come from the south. After the earthquake, the water in the Pasig River rose to a level reached only in the rainy season, and inundated the floodplains near shore. The next day, the water level fell below its usual mark as far as it had risen above the norm on the previous night (Perrey, 1860 b; Maso, 1895, 1910 a, 1926; Repetti, 1946) Iida et al., 1967). Berninghausen, 1969; Cox, 1970). [Iida et al. express doubt that this phenomenon was a tsunami.] Listed as questionable tsunami.

Reference #10958:

1828, November 9. Iida et al (1967) attributes this phenomenon to hydraulic effects rather than tsunami. Despite doubts raised by Iida et al about the certainty of this event as being a tsunami, this study ranks the tsunami probability as “positive” due to earthquake-tsunami cause-and-effect observation exemplified in the accounts.
