A so-called “rogue wave” famously struck Florida’s Daytona Beach on July 3rd, 1992.
The wave measured 12-15 feet in height and over 20 miles long. Fifteen years later the event still baffles scientists. Possible causes include a submarine slide, off-shore sinkhole collapse, decompression of underwater methane, or a meteorite 1-3 meters in diameter. Such a sighting was reported by a boater 8 miles off shore shortly before the wave struck the peninsula (read more).
How often do “rogue waves” strike?
Just last month Maine’s Boothbay Harbor got hit (read more), raising water levels 12 ft in 15 minutes, but fortunately doing so during low tide. That’s the first “rogue wave” that anybody’s seen in Boothbay Harbor since 1926.
