People run away from huge waves crashing onto San Sebastian's seafront in Spain February 17, 2006. A combination of several circumstances such as the full moon season, a squall over the Cantabrian Sea and heavy wind gusts reaching speeds of 110 km (68 miles) per hour contributed to create sea tides to levels not seen in the area for the past 3 years, with waves as high as 10 meters (33 feet).
