What the record says
NCEI’s account, from the sources it cites.
[In Chaguaramas Bay] waves generated were smaller than when a large boat passes. I also have a report from a homeowner directly across the bay from the island who says they suffered no damage of any kind and were not aware of any wave. (reference #12214)
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
