1) November 1970 - Approximately 150,000-500,000 deaths - Bhola Cyclone - Bangladesh (at the time East Pakistan). It was the deadliest tropical cyclone ever recorded, and one of the deadliest natural disasters in modern times. Up to 500,000 people lost their lives in the storm, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta.
2) April 1991 - Approx. 131,000-138,000 deaths - Bangladesh. Powerful tropical cyclone struck the Chittagong district of southeastern Bangladesh with winds of around 250 km/h (155 mph). The storm forced a 6 metre (20 ft) storm surge inland over a wide area, killing at least 138,000 people and leaving as many as 10 million homeless. the cyclone rapidly intensified to a 160 mph Cyclone, the equivalent to a Category 5 hurricane. Late on the 29th, Cyclone 02B made landfall a short distance south of Chittagong as a slightly weaker 155 mph Category 4 Cyclone. The storm rapidly weakened over land, and dissipated on the 30th over southeast Asia.
3) May and June 1965 (two cyclones) - Approx. 60,000 deaths - Bangladesh (at the time East Pakistan). Cyclone 1965 II Second cyclone in less than a month killed 35,000 people along the Ganges River, 1-2 June 1965.
4) October 1942 - Approx. 40,000 deaths - Bangladesh/India border (at the time all India). A wind gust of 225 km/h (140 mph) was recorded.
5) May 1963 - Approx. 22,000 deaths - Bangladesh (at the time East Pakistan).
6) November 1977 - Approx. 10,000-20,000 deaths - Andhra Pradesh Cyclone - India. a devastating cyclone that struck in the entire state of Andhra Pradesh and neighbouring states on November 19, 1977. It was one of the worst cyclonic storm to hit the Indian shores. A total of 14,204 people were confirmed to have been killed; however, some estimates place the loss of life at 50,000. Damage from the cyclone was placed at US$498.5 million.
7) October-November 1998 - Approx. 11,000-18,000 deaths - Hurricane Mitch - Central America.The most powerful hurricane of the 1998 Atlantic hurricane season, with maximum sustained winds of 180 mph (285 km/h). Hurricane Mitch was the thirteenth tropical storm, ninth hurricane, and third major hurricane of the season. At the time, Hurricane Mitch was the strongest Atlantic hurricane observed in the month of October, though it has since been surpassed by Hurricane Wilma of the 2005 season. The hurricane matched the fourth most intense Atlantic hurricane on record (it has since dropped to seventh).
8) September 1971 - Approx. 10,000 deaths - Orissa Cyclone - India.On October 27 a tropical depression formed in the Bay of Bengal. It continued north, strengthening until reaching a vertex of 115 mph winds. The cyclone hit Cuttack, a city in Orissa, India, on October 29, and dissipated 2 days later. The storm surge and flooding from the system caused 10,800 fatalities.
9) October 1999 - Approx. 10,000 deaths - Cyclone 05B - India. The 1999 Orissa cyclone was also known as Cyclone 05B, and Paradip cyclone, it was the deadliest Indian Oceantropical cyclone since the 1991 Bangladesh cyclone, and deadliest Indian storm since 1971. The Category Five storm made landfall just weeks after a Category 4 storm hit the same general area.
A tropical depression formed over the Malay Peninsula on October 25. It moved to the northwest and became a tropical storm on October 26. It continued to strengthen into a cyclone on October 27. On October 28, it became a severe cyclone with a peak of 160 mph (260 km/h) winds. It hit India the next day as a 155 mph (250 km/h) cyclone. It caused the deaths of 15,000 people, and heavy to extreme damage in its path of destruction.
10) September 1900 - Approx. 8,000-12,000 deaths - Galveston, Texas, United States. It had estimated winds of 135 miles per hour (217 km/h) at landfall, making it a Category 4 storm on the Saffir-Simpson Hurricane Scale.
The hurricane caused great loss of life with the estimated death toll between 6,000 and 12,000 individuals; the number most cited in official reports is 8,000, giving the storm the third-highest number of casualties of any Atlantic hurricane, after the Great Hurricane of 1780 and 1998's Hurricane Mitch. The Galveston Hurricane of 1900 is to date the deadliest natural disaster ever to strike the United States. By contrast, the second-deadliest storm to strike the United States, the 1928 Okeechobee Hurricane, caused more than 2,500 deaths, and the deadliest storm of recent times, Hurricane Katrina, claimed the lives of approximately 1,800 people.
