October 9, 2022 Tsunami: Stromboli Island, Italy
A tsunami caused by a volcano began at Stromboli Island, Italy on October 9, 2022 at 07:23 UTC. The water rose as high as 0.04 meters. Its effects were recorded at 2 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.

The toll
The record gives no deaths, injuries or damage for this tsunami.
What the record says
NCEI’s account, from the sources it cites.
The impact, at 9:23 am (Italian time) triggered a small tsunami wave recorded on all four sensors of the two Elastic Beacons placed on the sides of the Sciara del Fuoco. This is the fourth (small) tsunami recorded by the Medes since July 2019. The tsunami wave has a first positive impulse of about 2 cm, consistent with an underwater origin of the source, followed by a negative amplitude of about 5 cm produced by the call of water towards the impact zone. Amplitude and time of arrival at the two Mede coincide and indicate a source area equidistant to the sensors, consistent with the images of the surveillance cameras in the central portion of the Sciara. The preliminary localization indicates a distance of about 1100 m from the Mede and a propagation speed of about 32 m / s. (reference #13357)
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 |
|---|---|---|---|---|---|---|---|
| Punta del Corvo, Stromboli Island | Italy | 2 | 0.04 | Deep ocean gauge (half the maximum wave height) | |||
| Punta Labronzo, Stromboli Island | Italy | 3 | 0.04 | Deep ocean gauge (half the maximum wave height) |
