1931 China floods
There was no warning, only a sudden great wall of water. Most of Wuhan's buildings in those days were only one story high, and for many people there was no escape- they died by the tens of thousands. ... I was just coming off duty at the company's main office, a fairly new three-story building near the center of town ... When I heard the terrible noise and saw the wall of water coming, I raced to the top story of the building. ... I was in one of the tallest and strongest buildings left standing. At that time no one knew whether the water would subside or rise even higher.
