There's a rare wave in the ocean that you may have rarely heard of, but it does exist, unusually powerful and dangerous.
It appears twice as tall as the surrounding waves, up to 30 meters, and then forms extremely deep troughs that pose a huge threat to ships, and the sinking of some large ships may be related to it.
This rare wave, called Rogue waves or Freak waves, first appeared in a Japanese woodblock print in the early 19th century called Kanagawa Dailang.

In 1909, a steamship bound for Cape Town from Durban, South Africa, was thought to have suffered a mad dog wave, killing all 211 passengers and crew.
Although the Mad Dog Wave often appears in sailors' reports, it is fleeting, and scientists have difficulty filming it to study, and the exact cause of it is still unknown.
The first record of this eerie wave was more than 20 years ago on New Year's Day 1995, when the Drupnir oil rig off the Coast of Norway was hit by bad weather and was bombarded for most of the time by huge waves up to 12 meters high.
Shortly after 3 p.m., a huge 24-meter-high wave suddenly struck and crashed into the rig at 72 kilometers per hour, and the researchers got the first video of the mad dog wave.
In order to study this crazy wave, a team of scientists at the University of Oxford and the University of Edinburgh once used a 25-meter-wide circular pool to study the strange behavior of the waves, and finally unveiled the secret of the mad dog wave.
The results showed that when two columns of waves met at an angle of about 60 degrees, a mad dog wave could be produced — the crests and crests superimposed, and the troughs became deeper, with amplitudes up to twice as large.
Don't you think it's weird? The mechanism of mad dog waves is so simple that it may be so surprising to you that they can appear without warning and then suddenly disappear, and many unexplained shipwrecks are not its masterpieces?
We don't know, and may never know again, but scientists hope to continue research to create a simple theory that predicts this rare natural phenomenon by analyzing wave patterns in the ocean and avoids some shipwrecks.
