Asian Tsunami - causes and effects

Extracts from this document...

Introduction

The Asian Tsunami The 2004 Indian Ocean earthquake was an undersea megathrust earthquake that occurred at on Sunday 26 December 2004. This earthquake was the third most powerful earthquake recorded since 1900, and the confirmed death toll is just under 200,000 due to the ensuing tsunami ('soo-na-mi', from the Japanese words meaning 'harbour wave'). The hardest-hit and most severely affected countries were India (which was hit between 1 and 2 hours of the earthquake), Indonesia (which was hit within a few minutes of the earthquake), Maldives (which was hit within 4 hours), Sri Lanka (hit within 2hours) and Thailand (hit within an hour). Malaysia, Myanmar, Kenya, Seychelles, Somalia and the United Republic of Tanzania were also affected. The tsunami had the greatest impact on rural coastal communities, many of which were already poor and vulnerable and had few livelihood options. *Questions&Answers from sheet* 1.

Most of the LEDC's are unprepared since they do not have the evacuation plan, rescuing team, and food storage. They rely on the international aid (MEDC's) since the MEDC's have better rescuing team that have experiences. These problems happen because of the lack of money since they have a lot of corruption problems within the countries. The economy of the LECD's will be more affected than MEDC's because the ratio of the money that is used for reparation is higher. Furthermore, it will take LEDC's a longer time to recover from a disaster like a Tsunami. The areas hit were poorer parts of the world and in general, out of the countries hit, Somalia was the lowest developed country and Malaysia was the highest. According to the development table (on page 4 of the sheet), these measures tell us that most of the countries affected by the Tsunami, their development was significantly low: Somalia had a GNP of (US) $600, Birth rate of 42.71, life expectancy of 50.4 and adult literacy of 37.8%. ...read more.

Conclusion

* Obviously if they occur near to coasts then Tsunamis can cause a great deal of damage and deaths. * The area (rural and urban) Population density also affects the impact of an earthquake. Earthquakes can be a devastating phenomenon when they hit densely populated areas. Their effect can be greatly reduced in more sparsely populated areas, which are mostly the rural areas. * Distance from the epicentre The closer to the epicentre, the stronger the earthquake. Therefore earthquakes that have epicentres close to major urban areas tend to cause more problems than those that occur some distance from urban areas. * Emergency response Lack of emergency services and poor communication links in Less Economically Developed Countries mean that people are not rescued as quickly, or cared for as well, as they would be in a More Economically Developed Country. Also, in a MEDC, they would have a great deal of trained emergency personnel and equipment to help the injured. * Time of day Night time earthquakes can make it more difficult to rescue people immediately after an earthquake. However, there are few people on the street, in public buildings and at work. * Time of Year Earthquakes can result in higher fatalities if they occur in times of cold weather. ...read more.
