For hundreds of years, on the eighth month of the lunar calendar, people have gathered along the shores of China’s Qiantang River at the head of Hangzhou Bay to witness the waves of its famous bore tide. Higher-than-normal high tides push into the harbor, funneling into the river, causing a broad wave that can reach up to 30 feet high. If the waves surge over the banks, spectators can be swept up, pushed along walkways or down embankments. Below, I’ve gathered images from the past few years of the Qiantang bore tides.

This is an amazing set of images, where a cultural phenomenon is wrapped up in observing the pulsating physical geography of the river.  Usually the tidal bore is impressive (but not dangerous–see video here), but occasionally it can be incredibly violent (see this 2015 video).
