Impact Of Cyclone Nargis In Myanmar Environmental Sciences Essay

In May 2008, an extremely severe cyclonic surprise1 called Nargis induced the worst national natural disaster in the history of Myanmar. It killed almost 80, 000 people and hundreds of people are still missing in this catastrophic event1. The disastrous cyclone was initiated in the region of deep convection, that was established in the Bay of Bengal, in past due May and then intensified quickly into a severe cyclone with the action of warm water and upper-level troublesome1. This strong cyclone strike the coastal regions of Myanmar on May 2nd and brought serious harm to these areas. In this article, the major factor that contributed to such a significant loss of life during the surprise will be first talked about and then accompanied by the factors accounted for the great damage following the storm. The article will be concluded with some issues regarding the choice of individual on the cyclones' attack.

High surge wave

First and most important, the high surge wave helped bring by the cyclone Nargis was the most important cause for the fantastic damage during storm. The massive surge which was brought on by cyclone swept away everything like homes, roads and other infrastructure on its way in the inland area1. The 12 toes high influx swept away and inundated 50 % of house in the low-lying area. At least 10, 000 people in Bogalay got died as a result of storm surge1, it is a town 50 miles southwest of Yangon.

Flooding with several serious consequences

The secondary result was the flooding triggered by surge in the low-lying area. Flooded sea normal water ruined the agriculture area and other personal places. The high salinity of sea normal water destroyed the vegetations development there as well. Moreover, the land then became saltier rendering it unfavorable for the planting of vegetation and thus affected the meals supply in damaged area evermore. In addition, flooding caused the blockage of road which further broke down the general public move network. People could not get through the flooded area and this caused inconvenience to the people especially the elderly. Moreover, the electricity ability lines were ruined and this led to electricity shortage in the low-lying area for about six to seven days. Furthermore, the wells used to be providing clean drinking water were submerged by the ocean water. Because of this, the clean drinking water systems were polluted. To summarize, the meals, electricity and clean water cannot be found in the coastal portion of Myanmar and this insufficient resources further deteriorated the situation. Due to the absence of these three basic success elements for over four days, the amount of the death continued increasing to a unimaginable level.

Satellite images of flooding

In addition, the satellite image of Myanmar could display the destructive harm helped bring by flooding. In body 2, it could be seen that rivers and lakes are sharply witnessed as there is a sharp boundary between them and both the vegetation and fallow agricultural area on Apr 15. The Irrawaddy River moves in the southern direction and the Mouths of the Irrawaddy are created by numerous distributaries 2. The deep blue inexperienced area nearby the shore was wetlands. Cyclone Nargis attacked immediately the Mouths of the Irrawaddy and then changed to the northeast of coastline2. After 20 times, the coastal simple was flooded shown in physique 3. The agricultural areas had been totally damaged and most of the coastal areas were covered by sea water. For example, Yangon with society over 4 million was almost completely submerged by sea normal water whereas several large locations with populace from 100, 000 to 500, 000 experienced large magnitude of flooding2. The flooding converted the coastal areas of Yangon into muddy places.

Strong wind

Furthermore, the strong breeze brought plenty of damage to the Myanmar area. Cyclone Nargis was a strong Category 3 or minimal Category 4 hurricane with sustained winds of 130 mph and gusts of 150-160 mph3. The strong wind resulted in destructive damages to the environment. Since the area of Myanmar is very poor4, the residences were usually made only by skinny woods rather than cement. As the storm helped bring the strong breeze to the coastal area, almost all of the properties were demolished; it was because they could not withstand the broadband wind. More importantly, the breeze would bring all the dirt and shattered woods especially those from the residences along its track. This specifically endangered individuals lives for the reason that area, as the broadband flowing woods may kill any lives or properties along its way within a couple of seconds. Therefore, real human lives as well as properties were destroyed in large size under the influence of strong breeze.

Mudflow effect

Last but not least, the mudflow was one of the factors leading to large amount of fatality in Myanmar5. The heavy rainfall helped bring by the cyclones saturated the muddy area with water and so pressure would be built up on the mud surface. If the combination of normal water pressure and gravity of the dirt is larger than the resisting force, the high speed mudflow will take place. The mudflow which contained large amount of suspended debris and silt rushed into the coastal area, hence many residents of low-lying rice fields were simply swept away in Maynmar4. It had been estimated the loss of life has gone to 140, 000 conditions or more. People were crashed with the damaged woods in mudflow, swept away or suffered from suffocation4. A whole lot worse, the mud flew on the coastal area prohibited the excavation of the buried people, which makes it more difficult. The mud clogged the travel network which provided a difficult task to catastrophe management; and would cause serious damage.

Poor management of international relief

From above, we've screened through the factors triggering significant destruction through the passing of strong cyclone. Then, the dialogue should move to the factors of great injuries after the storm. The blockage of international comfort by the armed forces government was a major reason for the fantastic devastation of lives and properties6 after the storm. Many disaster assessment officials experienced to hold back for couple of days in order to obtain the visa and enter section of Myanmar6. This further hindered the comfort work as the international pain relief clubs and private charity groups were not permitted to fully assess the situation. As the catastrophe could not be fully assessed, teams cannot estimate the quantity of relief materials and other products required promptly. In addition, as mentioned before, Myanmar is an unhealthy country which does not have enough alleviation technology and equipment to help rescue the buried people out of the mud flow. Due to the preliminary blockage from the military services government, the international alleviation team cannot enter into the influenced areas rapidly. This delayed the time of the entrance of foreign alleviation teams and for that reason, the majority of them showed up there after three days of the function. However, the success time period limit of individual buried in dirt or even dirt was only forty-eight hours and this increased the number of death. In fact, when the groups finally arrived, they could only do little as the gold period had passed through6.

Blockage of assess

In addition, access was a task for the recovery teams to face. The United Country estimated that there are 1. 4 million of survived victims who need resources like food, clean water, medicine and shelter7. However, the majority of the flooded area could not be entered by trucks. Instead, the helicopters were required to transport the alleviation materials. The problem worsened because the Myanmar authorities was too poor to have enough helicopters. Moreover, it took time in sending extra helicopters from other countries. Eventually, the officials allowed the first of ten helicopters from the planet Food Program to carry water and food products from Yangon in to the delta after a 10-day delay. The other nine were on the way to Myanmar7. Some people died out of hunger as the materials reached the impact area only following the ten days wait.

Secondary damage of flooding

Besides, the tidal surge drove inland from the sea caused secondary damage to the cities of Myanmar8. Three quarters of livestock were wiped out and almost half the fishing fleets were sunk. Additionally, a million acres of rice paddies were salted by the seawater surges8. This flooding of seawater slice the local food resource and inundated the low-lying area. Normal water pipes and electricity electricity lines were damaged that people had to endure through four days without electricity and clean drinking water. A whole lot worse, the flooded areas remained flooded for a week and this was polluted by the dead systems. 'There was a clear lack of sanitation facilities for the 500 people. ' said by an official from red cross9. People had no selections but had a need to drink the polluted normal water to be able to endure. This resulted in the get spread around of water-borne diseases like cHYPERLINK "http://en. wikipedia. org/wiki/Cyclosporiasis"yclosporiasis and aHYPERLINK "http://en. wikipedia. org/wiki/Amoebiasis"moebiasis. Studies of digestive tract disorders and malaria were been told and one in five people was reported ill9. Furthermore, having less transport resulted in a shortage of medication. When people got sick and tired because of drinking alcohol unclean drinking water, their situations would probably worsen plus they may expire eventually. This brought on a viscous cycle.

Cyclonic surprise1 called Nargis was the most detrimental national natural devastation on the history of Myanmar. Both the natural and individuals factors greatly get worse the impact brought by cyclone which induced lots of loss of life and damages. Natural factors like high surge wave, mudflow and flooding reconstructed the low-lying portion of Myanmar; whereas individual factors like poor prep for the cyclone and delay of the comfort clubs further worsened the situation and increased the number of the fatality and damage of properties. The coastal low-lying portion of Myanmar originally got fertile land and favors agriculture10. However, after the surprise, all the agriculture areas were inundated by overflow water; and the farmers lost all their farming products in three time10. The energy of nature cannot be modified by individual and this can be well demonstrated by the example that cyclone Nargis struck Myanmar. Sadly, people needed to make money so they chose to stay there. Alternatively, Hong Kong, as an Asian city also, is usually sheltered. Hong Kong people probably never provide a serious thought on exactly what will happen if this typhoon hit our city instead. Some of us might even pray that the typhoons could harm Hong Kong straight so that there will be no working or college days. Hong Kong is a safe place that no person can bear in mind the dangerous typhoon and it leads to our neglect of unfortunate catastrophe elsewhere on earth. Should we change our frame of mind and understand more about how people are affected in the other part of world; and in the end show more care and attention to the unlucky ones?
