Background from Wikipedia

The 1970 Bhola cyclone, also known as the Great Cyclone of 1970 or simply the Bhola Cyclone, was the deadliest tropical cyclone on record, as well as one of the deadliest humanitarian disasters ever recorded. It struck East Pakistan and India's West Bengal on 12 November 1970. At least 300,000 people died in the storm, possibly as many as 500,000, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. The Bhola cyclone was the sixth and strongest cyclonic storm of the 1970 North Indian Ocean cyclone season.
