World's Largest Tidal Bore
In China, Qiantang tide is a remarkable natural phenomenon and is one of the world's wonders. Watching the tidal waves of the Qiantang River has been a significant event for over 2000 years. The tidal waves go up to as high as 9 meters, traveling at up to 40 km/h (25 mph) making an earthshaking sound and seeming to stem from the momentum of an avalanche.
