I chose this case study on the 1970 Bhola Cyclone, because it was one of the first natural disasters to capture my attention. It is also one of the biggest natural disasters to occur in world history.
The storm originated in early November by a tropical storm that had moved across the western part of Malaysia. After a while the tropical storm had reached the Bay of the Bengal, where the water is famous for how warm it is. During this time that the storm has reached the Bay the storm had begun to build greatly. The time that the storm began to intensify is recorded to have begun on the eighth of November. By the ninth of November reports stated that the storm had reached its tropical storm potential. At precisely high tide the storm had arrived at the Ganges on the early morning of November 13th. As the storm was heading northward towards East Pakistan the storm was beginning to build very quickly and fast. Before the storm could reach its full potential, the satellites were able to get a close approximation as to what the average wind would be at landfall and the wind gust. The average wind fall at landfall was expected to be at 140 miles per hour. At the time of high tide the storm surge had reached twelve feet. With the storm surge being at twelve feet that was additional ten feet to the measurement of the sea level already. As a result of all the storm surges this caused the storm surge to reach a total of twenty feet. (Emanuel, 2005, pp. 221-25)
The reconstruction phase consisted of rebuilding almost everything because the storm destroyed everything, including buildings, homes, and agriculture. Since Bangladesh is subjected to receiving these natural disasters frequently they are continually revamping their storm systems and shelters, so the reconstruction phase is forever continuing. Extensive amounts of mitigation was started after the storm took place in Bangladesh and they invested in preventable infrastructure and embankments. Besides their indestructible infrastructure and their steps to better mitigate the area, they have taken other precautions too. They have built better cyclone shelters and made evacuation routes so people have ways to escape before the storm can worsen. They have invested their time in bettering their communication systems and have developed credible warning systems along with investments in extraordinary and user friendly relief systems. For the future, they have used all of these preparation tactics, since cyclones are common in Bangladesh. Along with the other preparation systems they have gotten involved with the national Cyclone Preparedness Programee (CPP) and that has helped them to improve and reduce the amount of destruction that occurs during and after a storm strikes.
