What the record says
NCEI’s account, from the sources it cites.
1908 (1907). Several km (miles) south of Tongatapu Island
(21.17 S., 175.13 W.), a submarine eruption occurred, which was accompanied by a strong earthquake on Tongatapu and by a tidal wave. The event generated a large column of steam, along with pumice on the surface of the ocean. [Possibly distorted information about a previous event.] (reference #415)
1907, July. Submarine eruption. (reference #2432)
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
