Present day Bangladesh, due to its unique geographic location, suffers from devastating tropical cyclones frequently. The funnel-shaped northern portion of the Bay of Bengal amplifies the storm surge of landfalling tropical cyclones, affecting thousands of people. Some of the most devastating natural disasters in recorded history with high casualties were tropical cyclones that hit the region now comprising present-day Bangladesh. Among them, the 1970 Bhola cyclone alone claimed approximately 300,000 to 500,000 lives, making it the deadliest tropical cyclone on record.
