What the record says
NCEI’s account, from the sources it cites.
Ref #13377 lists abnormal currents and waves were observed in Central Provinces but there was no report of damages. Slight increase in sea level was experienced around parts of Guadalcanal including Marau, Lambi and Hulavu.
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 |
|---|---|---|---|---|---|---|---|
| Honiara, Guadalcanal | Solomon Islands | 58 | 0.03 | Tide gauge (half the maximum wave height) |
