sentences:  No record of any seismic event in the Caribbean on 29 August 1916 that could have triggered a tsunami has been found, and the rate of advance of the large wave "Castine" and "Memphis" reported—about an hour to cross the distance from the horizon to the ships—matches that of a wind-generated ocean wave (possibly a rogue wave); a tsunami, in contrast, would have covered the distance in only a few minutes.The periods of the three large waves that struck "Castine" and "Memphis" also are characteristic of large wind-generated waves rather than tsunamis.A likely source for such large, wind-generated waves in Santo Domingo Harbor on 29 August 1916 does exist, in that three hurricanes active in the Caribbean between 12 August and 2 September 1916, (the first struck Corpus Christi, Texas, on 18 August 1916) passed westward just to the south.
