What the record says
NCEI’s account, from the sources it cites.
On January 25, 1972 at 10:06 [local time] an earthquake occurred on Taiwan, generating a weak tsunami. Ishigaki Jima. No other data were available on this tsunami. (reference #417)
tsunami magnitude -1 (reference #150)
January 25, 1972, 22.6 N, 122.3 E, depth 29 km, magnitude 7.4 Ms, tsunami magnitude 0 (reference #11134)
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 |
|---|---|---|---|---|---|---|---|
| Hualien | Taiwan | 177 | 0.02 | Tide gauge (half the maximum wave height) | |||
| Ishigakiko | Japan | 279 | 0.05 | Tide gauge (half the maximum wave height) |
