Annual Wave | National Geographic

once a year thousands come to China’s
Hangzhou Bay to witness a freakish sight
an annual tidal wave under the late
summers full moon the tide in the bay
surgeons 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 nine feet high and it closes in
facts
with a force like a locomotive the wave
sweeps dozens away instantly
others try to outrun it
only to be overtaken
in all it engulfs 30 people amazingly
while a few barely escaped drowning no
one is killed
