PHOTOS: 30 injured by Haining Tide in China

In this Thursday Aug. 22, 2013 photo, spectators flee as waves created by a tidal bore crash over a barrier on the Qiantang river at Haining, in east China's Zhejiang province. About 30 people were injured when they were caught too close to the river while viewing the annual tidal bore, which occurs when sea water from an unusually high tide funnels into the river, creating high waves.

This picture taken on August 22, 2013 shows onlookers running away from huge waves from the "Haining tide" - a daily occurrence when the river tides hit the banks of the city - as they surge higher than usual due to the influence of Typhoon Trami in the region in Haining, in eastern China's Zhejiang province. Typhoon Trami, the 12th typhoon to hit China this year, brought rainstorms and wreaked havoc in eastern China after landing in Fujian Province early on August 22. The tides there have attracted spectators for the past two millennia, and it is the scene of an annual Tide-Watching Festival in late summer. AFP PHOTOSTR/AFP/Getty Images ( 522273418 )
