In 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
