September 22, 2022 Tsunami: S. Mexico
A tsunami caused by a magnitude 6.8 earthquake began at S. Mexico on September 22, 2022 at 06:16:09 UTC. The water rose as high as 0.09 meters. Its effects were recorded at 3 places. It killed 2 people, counting the earthquake or eruption that caused it.

What the record says
NCEI’s account, from the sources it cites.
Note: Reference #13342 does not say this is a tsunami. A possibility is tide gauge records represent local seicheses, as the amplitudes and the periods of these practically do not change with time, triggered by long waves. Further investigation is required.
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 |
|---|---|---|---|---|---|---|---|
| Lazaro Cardenas | Mexico | 90 | 0.05 | Tide gauge (half the maximum wave height) | |||
| Zihuatanejo | Mexico | 163 | 0.07 | Tide gauge (half the maximum wave height) | |||
| Manzanillo | Mexico | 169 | 0.09 | Tide gauge (half the maximum wave height) |
