The 1970s were a terrible decade for typhoons and cyclones too:

Cyclone Bhola, which left an estimated 300,000 dead when it hit what was then East Pakistan in 1970, is the world’s deadliest tropical cyclone on record.
In the same year, two of the deadliest typhoons on record hit the Philippines. Super typhoon Joan brought 175 mph winds and killed 768 people in October 1970. A month later Patsy left another 746 dead in its wake.
Cyclone Tracy, which hit Australia in 1974, is the deadliest in Australian history. The storm caused significant damage, destroying 80% of the buildings in Darwin. It also claimed 71 lives, injured 650, left 41,000 homeless, and caused 35,362 people to evacuate. Every single tree in Darwin was uprooted and stripped of its foliage, an indication of how intense the small storm really was.
China was struck by the short-lived but intense Super Typhoon Nina in August 1975. As a result of the typhoon, the Banquio and Shimantan Dams collapsed, causing unprecedented flooding and destruction downstream.
The storm brought heavy rainfall as it stalled over this area for 3 days. Approximately 1,060 millimeters (41.7 inches) of rain fell during those three days. The storm produced more rainfall in 24 hours than an average year’s worth of rain in the Henan Province, 800 millimeters (31.5 inches).
The disaster is reported to have flooded 29 counties in the Henan Province, affected 11 million people and killed over 85,000 (Henan is China’s most populous province).
1979 brought Typhoon Tip, which was the most intense tropical cyclone ever observed, with a central pressure of 870mb It was also the largest.
