Grant "Twiggy" Baker braved a 65 foot wall of water off the coast of San Diego, California. He is one of the "Big Wave Surfers" who risk everything to ride the biggest waves Mother Nature has to throw at them.Baker said he understood that any mistake may result in very serious consequences. via dailymail.co.uk

It often happens that people challenge the elements wanting to conquer and tame them. This was exactly that situation. The stormy weather has created 50 ft waves which is very unusual for this region.Lee William and Charlie Thompson, both 21 wanted to ride the massive waves off the coast of Penzance in Cornwall. Their friend Jacob Cockle, 22 was there to record the event. The two surfers were prepared to surf the big wave, however it was not meant to be. The wave came crashing, tossing and throwing the surfers around. It's clearly seen on the photos. The surfers, a little beat up, but feeling

In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two mediums (e.g. the atmosphere or ocean) which has the restoring force of gravity or buoyancy. When a fluid parcel is displaced on an interface or internally to a region with a different density, gravity restores the parcel toward equilibrium resulting in an oscillation about the equilibrium state. Gravity waves on an air-sea interface are called surface gravity waves or surface waves while internal gravity waves are called internal waves. Ocean waves and tsunamis are examples of gravity waves.

Not the brightest idea to take the boat out in these conditions.

Twice a year, on February or March, the Atlantic Ocean waters roll up the Amazon river, in Brazil, generating the longest wave on the Earth. The phenomenon, known as the POROROCA is caused by the tides of the Atlantic Ocean wich meet the mouth of the river. This tidal bore generates waves up to 12 feet high which can last for over half an hour. The name "Pororoca" comes from the indigenous Tupi language, where it tmeans "great destructive noise". The wave can be heard about 30 minutes before, and it's so powerful that it can destroy anything- trees, local houses and all kind of
