What the record says
NCEI’s account, from the sources it cites.
Reference #236:
1906, July 1. Heck (1947) lists a sea wave occurring on this date in the Marshall Islands. Both Soloviev and Go (1974, p. 192) and Iida et al, (1967) state that Heck's
source, Mitteilungen, Petermann (1906), does not mention a sea wave. No earthquake was located by Gutenberg (1956) in the area. This is a doubtful tsunami.
Reference #414:
1906, July 1. Validity questionable. There was a tsunami in the Marshall Islands (Heck, 1934, 1947; Ponyavin, 1965). The primary source, to which Heck refers, gives no data on tsunami. A very doubtful case (Iida et al., 1967).
Reference #132:
1906, July 1. Marshall Islands. Sea wave.
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
