What the record says
NCEI’s account, from the sources it cites.
The paroxysm of the 19 May 2021, starting at 12:51-12:52 UTC, triggered a Tsunami, measured in at least 3 locations around the Stromboli Volcano. The highest on-shore measured height was about 70 cm in Ginostra (peak-to-peak amplitude). (reference #13740)
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 |
|---|---|---|---|---|---|---|---|
| Ginostra, Stromboli Island | Italy | 2 | 0.36 | Tide gauge (half the maximum wave height) | day 19, 12:53 | ||
| Strombolicchio, Stromboli Island | Italy | 5 | Deep ocean gauge (half the maximum wave height) |
