What the record says
NCEI’s account, from the sources it cites.
Reference #236:
1912, December 6. An earthquake (similar to that of 1912, October 31) was felt and heard in the Yap Islands at about 3:11 P.M. Immediately after the earthquake a wave was
seen at sea. The quake was not reported by seismological stations in the area. (Soloviev and Go, 1974, p. 192)
Reference #414:
1912, December 6, 15:11 [local time]. Validity questionable. Magnitude 7. On Yap Island, there were undulating tremors of an intensity of 3 degrees (R-F), lasting 4 seconds; they were accompanied by an underground rumble. Two weak recurrent shocks were felt at night. Immediately after the earthquake, a wave was observed at sea (Maso, 1912b). [The earthquake was apparently not registered by the East-Asian seismic stations: Manila and others.]
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
