June 7, 2026 Tsunami: Mindanao Island, Philippines
A tsunami caused by a magnitude 7.8 earthquake began at Mindanao Island, Philippines on June 7, 2026 at 23:37:41 UTC. The water rose as high as 2.5 meters. Its effects were recorded at 40 places in at least 5 countries. It killed 107 people, counting the earthquake or eruption that caused it.
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.
Six shanties on stilts were damaged in a coastal village in Zamboanga del Sur province due to the quake and taller waves, officials said. (reference #14391)
Two swimmers drowned and one remained missing off General Santos after being swept out to sea shortly after the quake hit. (reference #14400)
Reference #14435 reports a maximum runup height of 2.5 m in Brgy. Salaman, Lebak.
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
