[QUOTE=Hartleyg;2973598]Its unlikely that wave made it to shore, or even existed for very long. Rogue waves form when multiple smaller waves combine into a monster - but the constituent parts
are not moving at the same speed or direction, so they don't tend to last long. /QUOTE]
The article says that the rogue wave
you're referring to when multiple waves combine into one large wave is called interference
. There's no way to know but this one might have been created by both bathymetry (typical for natural big wave area) and interference
. The article says:
"Given how relatively close this measurement was recorded to shore, odds are that this wave may have been helped along by two processes: bathymetry and interference. “The Cabot Straits bathymetry is varied, with the Laurentian Channel creating a deep trench through its metre,” explained Walsh, “and comparatively shallow coastal waters closer to Newfoundland
and Cape Breton Island.” While these conditions are impossible to validate, Walsh said that these conditions have been known to foster the development of these rare rogue waves before.
In which case, I'd expect that someone standing on shore would have noticed....
