In 1737, Calcutta witnessed one of the worst cyclones in recorded history of India. Hurricane force winds were reported to be accompanied by an earthquake and extensive flooding with an estimated death toll of 3,00,000.
The absence of evidence for soil liquefaction suggests that perhaps no substantial earthquake occurred. The population of Calcutta, a new city which was being established by Job Charnock at that time was around 3,000 to 20,000.
The fatalities estimated in London and French journals exceeded the official report of more than 3000. Although official reports discussed only the damage in Calcutta, it is possible that the 3,00,000 estimated fatalities included those in coastal villages in what is now West Bengal and Bangladesh.
