It reveals that the cyclone of 1876, 1919, 1961, 1963, 1965, 1970, 1985, 1988, 1991, 2007 and 2009 were severe in nature. periods. In 2007, Cyclone Sidr occurred on November 15, 2007, that claimed up to 10,000 lives, according to Red Crescent Society. UNICEF (1993) cyclone evaluation team during their post cyclone (1991) survey observed that almost all deaths have been as a result of drowning from the tidal wave that accompanied the cyclone. Cyclone Marion : On the evening of April 29, 1991, the 5th deadliest recorded tropical cyclone of the 20. th. Cyclones can cause immense loss of life and destruction of property during pre-monsoon (April- May), and post-monsoon (October-November.) In 1991, a cyclone occurred on April 29 of the year affecting Chittagong district of southeastern Bangladesh. From 1970 to 1998, there were 38 severe devastative cyclones in the context of destruction and loss of lives or economy.

According to this view, the "natural disaster" of April 1991 could more accurately be called a "social or political disaster." The Figure 1, shows the cyclones crossing Indian coast- line and coast-line of other countries like Bangladesh (14.5%), Myanmar (7%), and Sri Lanka (1.2%) shows that most of the cyclones developed over the Bay of Bengal crosses Indian coast line accounts to 60.8%, which is the next highest number of cyclones dissipated over the sea. In 2007, Cyclone Sidr occurred on November 15, 2007 that claimed up to 10,000 lives, according to Red Crescent Society. Heavy rains accompanying cyclones, and the tidal waves due to wind effects, called storm surges, cause most of the damages.
century hit the densely populated Chittagong region of Bangladesh… Bangladesh is perhaps the most unique country in the world where casualties resulting from a cyclone could rise into the hundreds of thousands, for example, the October 1970 cyclone that killed an estimated 500,000 people and the April 1991 cyclone that killed an estimated 140,000 people (see Haider, et al., 1991).

In 1991, a cyclone occurred on April 29 of the year affecting the Chittagong district of southeastern Bangladesh. More than 10 million people became homeless due to the cyclone. these that can and must be mitigated in order to reduce fatalities and other devastating impacts of natural disasters. The April 1991 Cyclone: A powerful tropical cyclone struck the Chittagong district of southeastern Bangladesh on April 29, 1991. At least 138,000 people were killed by the cyclone. The FE started its journey in 1993. Among them the cyclone of 1970 are the worst and remarkable for the causes Heavy rains accompanying cyclones, and the tidal waves due to wind effects, called storm surges, cause most of the damages. It caused a damage of around $1.5 billion. In 1999 in India's Odisha state, 10,000 people were killed by a cyclone.

The 1991 Bangladesh cyclone occurred on April 29th, 1991 and is one of the deadliest tropical cyclones killing at least 138, 000. periods. Cyclone Sidr (Table 2) hit the coastal areas on 15 November 2007 with winds of 250 km/h and a five meter sea surge, killing more than 3,300 people. The cyclone of 1876, 1919, 1961, 1963, 1965, 1970 and 1991 were severe in nature. The Bay of Bengal is the breeding place of catastrophic cyclones. In 1991, a cyclone occurred on April 29 of the year affecting the Chittagong district of southeastern Bangladesh. A natural disaster might be caused by earthquakes, flooding, volcanic eruption, landslide, hurricanes etc. The 1991 cyclone of Bangladesh, known as BOB 01, was the most catastrophic and deadliest tropical cyclone that struck near Chittagong on the southeast side of Bangladesh on 29 April 1991. Cyclones can cause immense loss of life and destruction of property during pre-monsoon (April- May), and post-monsoon (October-November.) 1). Hoque, 1991). Approximately 20 years later, on April 29, 1991, the coastal region of Bangladesh was struck by another great tropical cyclone, which killed over 135,000 people (Chowdhury et al. Some 138,000 died in Bangladesh in 1991 in a tidal wave caused by a cyclone. Figure 1. method of data collection. in the months of April, May, October and November. 1993).
