Rejected as a myth, a 60-foot rogue wave swells in British Columbia


According to a new study, the 58-foot-high giant swell that crashed off British Columbia, Canada in November 2020 was identified as the largest “huge” wave ever recorded.

Scientists say the rogue waves that hit off the coast of Vancouver Island reached almost the same height as a four-story building. The characteristics of the waves are explained in detail in a study published on February 2. Journal Scientific Reports..

Illegal wave Is an unusually large swell that occurs in the open ocean and grows more than twice as high as other nearby waves. These unpredictable and seemingly random events are sometimes referred to as “freak” or “killer” waves, and little is known about how they are formed.

Johannes Gemmrich, a research scientist and lead author of the study at the University of Victoria, said the 2020 event was “the most extreme rogue wave ever recorded” in proportion to the surrounding waves. Said.

“There are very few fraudulent waves observed directly in the high seas, and nothing of this size,” he said. Said in a statement.. “The probability of this happening is once every 1300.”

The huge swell was picked up by a buoy sensor on the west coast of Vancouver Island, just over four miles from Yucuretto.

For centuries, fraudulent waves were considered a nautical myth, but were rejected because of exaggerated explanations created by high seas sailors. However, in recent decades, scientists have been able to confirm the existence of fraudulent waves, which are still difficult to observe and measure.

The first recorded fraudulent wave occurred off the coast of Norway in 1995. Known as the “Drapner Wave,” the event reached a height of nearly 84 feet, twice as large as the surrounding waves. The 1995 rogue waves were generally taller than those measured off the coast of Yucuret, but the record-breaking 2020 event was nearly three times as large as the other waves around it, researchers said. Et al. Said.

Studying fraudulent waves may help scientists better understand the forces behind them and their potential effects, and ocean sensors around North America, including those recording Ucluelet waves. Said Scott Beatty, CEO of Marine Labs, a research firm that operates the buoy network.

“The unpredictability of rogue waves and the strength of these” water walls “can be extremely dangerous to marine activity and the general public,” he said in a statement. ..

Beatty added that being able to track and analyze these anomalous events helps improve maritime safety and protect coastal communities.

“The possibility of predicting rogue waves is an open issue, but our data better understand when, where, and how rogue waves are formed, and the risks they pose. Helps, “he said.
