Introduction

14th October 2003 Unit 24- Major Incidents Task 1 For this assignment I have been set the task of examining three disasters and the various ways in which they occur. I will need to provide a written description of three different disasters. * One caused Naturally * One caused by Human Action * One caused Technologically Natural Disaster The natural disaster that I have chosen to write about is the great floods of 1953. The east coast floods of 1953 were mainly caused by what is known as 'storm surge'. A storm surge occurs at the centre of the storm where the pressure is at its minimum, causing sea levels to rise up to 10 metres. The result being, serious flooding of all low lying coastal lands. With the east coast this caused the sea levels of some areas to rise by nearly 3 metres above normal high water marks. Defences along the coast were damaged and overtopped by huge waves. In 1970 a far more disastrous storm surge occurred in the Bay of Bengal killing 300000 people in northeast India and Bangladesh and made a further two 2.5 million people homeless. The great floods started on the morning of Saturday January 31st 1953. ...read more.

Human Action Disaster The human action disaster that I have decided to write about is the Lockerbie Crash. On December 21st 1988 flight Pan AM 103 flew from London Heathrow to New York, the aircraft carried 259 people, of which 16 were crewmembers. None of the 259 people on board the plane survived; also 11 residents of Lockerbie were killed. Major parts of the aircraft fell on the town of Lockerbie with other parts landing in the countryside to the east of the town. Later parts of the plane were found 130km away on the east coast. Scottish Police spent months searching for parts of the aircraft. In July 1990 the concluding report was published stating that the crash was caused by the 'the detonation of an improvised explosive device located in a baggage container. Suspicion fell upon two Libyan Air Officials, in Valletta at the time, Abdel Baset al-Megrahi, 46 years old. Al-Amin Khalifa Fhimah, 42 years old. The trail itself was held in Netherlands, in January 2001 Al Megrahi was jailed for life for his part in the bombing of Pan Am Flight 103. His co-accused, Al Amin Khalifa Fhimah, was found not guilty by three judges at a specially convened Scottish court in the Netherlands. ...read more.

Conclusion

The sudden increase in heat caused the fuel to rupture and react with the water resulting in a steam explosion that destroyed the reactor core. 2 to 3 seconds later a second explosion added to the destruction. Post accident assessments laid most blame on the operator but later assessments shared the blame between the operator and the design faults of the reactor. The explosions sent radioactive debris about 1km into the sky and clouds of steam and dust began to rise. A great mass of fire was breaking out and many firefighters lost their lives trying to extinguish them. By 5.00am the fire was out. On May the 9th a concrete barrier was to be built to prevent the any further escape of radiation. It was too late because wind directions had already taken radiation to surrounding areas and even neighbouring countries. Today people are still being born with disabilities and illnesses due to this major accident. Conclusion In conclusion with all three accidents in some form or another they were down to human errors. Chernobyl was down lack of safety and operating at dangerous levels. The Lockerbie crash was caused by an explosive device in the luggage. Finally, although the floods were not down to human error, coastal flooding is always a possibility and stronger prevention measures could have been used. ...read more.
