It took me about thirty seconds to research the accuracy of the graph. The Red Cross described 1927 as the worst year in history, reporting 111 disasters – including 29 tornadoes, 24 floods, 9 hurricanes and 23 fires. The worst floods in US history occurred that year. The Mississippi River was flooded for more than six months, forcing hundreds of thousands of people to abandon their homes permanently. Vermont’s worst flood also occurred in November, 1927.

Obviously the person who generated the graph didn’t do any research, and is simply making numbers up. Another graph from the same website shows death rates from natural disasters down 95% since the 1920s.
