Wired News: Freak Waves Are No Tall Tale:

“In 2001, two cruise ships in the South Atlantic – the Bremen and the Caledonian Star – reported that their bridge windows were smashed by 100-foot rogue waves.
Researchers suspect that rogue waves also played a role in the sinking of some of the 200 large supertankers and container ships that have gone down in bad weather over the past two decades.
Unfortunately for those in harm’s way, there is still much more research to be done before a solution can be proposed. For instance, no one yet seems to know how the waves are formed in the first place.
‘We don’t know what’s going on out there,’ said Paul Liu, an oceanographer and rogue-wave researcher with the National Oceanic and Atmospheric Administration.”

Lovecraft was right! In the depths the mighty one awakes from his eternity of sleep.
