Most extreme rogue wave ever was recorded off B.C. coast
rogue wave ever recorded has been measured off the coast of Vancouver Island, near Ucluelet, B.C.The wave, measuring 17.6 metres – which is as high as a four-storey building – was recorded in November 2020 by Victoria, B.C.-based MarineLabs Data Systems.It is the subject of a scientific report by Dr. Johannes Gemmrich and Leah Cicon, from the University of Victoria, and published last week in the journal, Scientific Reports.Rogue waves are waves with more than double the height of the waves currently happening around them. According to MarineLabs, they can also be known as “freak” or “killer waves” as they can occur unexpectedly, and, because they are so huge, can be very dangerous.
