heat in our atmosphere is likely to lead to stronger winds, which in
turn are going to create bigger waves. This is likely to pose
serious and inceased threats to shipping and coastal communities.
The theoretical maximum wave height is 50 meters.
2004 - Rogue
waves are believed to have sunk more than 200 supertankers and
container ships over the past two decades.
Long thought to be
a myth, freak waves as high as 10-storey buildings are far more
common than previously thought, the European Space Agency has found.
weeks of imaging data by the agency's satellites from early 2001
showed more than 10 individual giant waves around the globe of more
than 25 metres in height. Previously, scientists believed that such
large waves occurred only once every 10,000 years.

heights in the Pacific Ocean, showing a wave of nearly 30 meter
November 2002 the tanker 'Prestige' carrying 80,000 tonnes of crude
oil encountered a heavy storm and it's hull was breached off the
Spanish coast. The tanker was towed further away from the coast
before it broke in half and sank several days later. Experts believe
that the damage clearly visible in this image (on right) was caused
by a very big wave. www.spiegel.de/wissenschaft
The wave in the image
above left was encountered by the 'Mariner' in 1993, the one on the
right by the super tanker 'Esso-Languedoc' in 1980.
The image on the left
shows the damage sustained by the 'Wilstar' in 1974, when a giant
wave slammed into the ship. www.spiegel.de/wissenschaft
Mai 2007 – 2000km of coast line from Sumatra to Bali were hit
by unusually high waves, causing extensive damage to buildings and
fishing boats. People ran for high ground for fear of another
tsunami, but the giant waves were simply casued by strong winds over
the Indian ocean.
