Huge 20-meter 'rogue waves' are actually real

Recent research has shown that massive waves can appear out of the blue with surprising regularity.
For centuries, mariners have told tales of ships being swallowed up by enormous waves that can rise up out of nowhere before disappearing again just as quickly.

Until relatively recently these accounts were generally dismissed as mere tales, but in the 1950s the idea started to be taken more seriously after scientists suggested that it was actually possible for such waves to occur, albeit once every 30,000 years or so.

In December 1978 however, a distress call was picked up from a German cargo ship in the mid-Atlantic. The ship itself was never found, but it seemed that something unexpected had befallen it.

By analyzing the damage sustained by one of the vessel's lifeboats, scientists determined that the ship had been struck by an extreme force - most likely due to a collision with a huge wave.

Then in 1995, the Draupner oil platform off the coast of Norway, which had been subjected to hurricane winds, was unexpectedly struck by an enormous 26-meter wave.

The final nail in the coffin for any remaining skepticism concerning rogue waves occurred in 2003 when scientists at the European Union's MAXWAVE project studied thousands of satellite images over a 3-week period and found at least 10 waves exceeding 25 meters in height.

Rogue waves, it seems, are neither fictional nor rare and actually occur with alarming regularity.

Very interesting subject. I remember the 'Horizon' episode from years back. It always fascinates me.

The Indian Ocean tsunami of 2004 was said to be 50 feet high in certain areas. Though I would guess that it's not the height so much - just the sheer volume and force of water that caused the most problems. "A tsunami may be less than a foot (30 centimeters) in height on the surface of the open ocean, which is why they are not noticed by sailors. But the powerful pulse of energy travels rapidly through the ocean at hundreds of miles per hour. Once a tsunami reaches shallow water near the coast it is slowed down. The top of the wave moves faster than the bottom, causing the sea to rise dramati... [More]

Although there are two main conflicting theories apparently they have found that some areas of ocean are more prone to creating these waves than others: Using satellite imagery, it became obvious the there are certain areas around the globe that are more prone to Rogue Wave activity. Places where ocean currents meet waves that travel at opposite directions are especially dangerous. Those areas were quickly removed from shipping lanes listings. http://thefutureofthings.com/3698-the-wave-that-changed-science/ ERS-2Satelliteimage of a 29.8 meterwave http://www.esa.int/Our_Activities/Observi...

As a novice, this seems hard to believe. - travels rapidly through the ocean at hundreds of miles per hour I'm not saying it is wrong, just that it is hard to believe. That would be over 200 miles per hour, at least.
