Once a year, thousands come to China’s Hangzhou Bay to witness a freakish
sight – an annual tidal wave. Under the late summer’s full moon, the tide
in the bay surges. Even in a normal year, it’s an awesome display. But
this is not a normal year. When the wall of water arrives, it’s more than
9 feet high, and it closes in fast. With a force like a locomotive, the
wave sweeps dozens away instantly. Others try to out run it, only to be
overtaken. In all, it engulfs 30 people. Amazingly, while a few barely
escape drowning, no one is killed.
