Natural Hazard Case Study: Tsunami the Great Wave
Introduction: Natural Hazard
There are many natural hazards phenomenon that scared the land everywhere worldwide. Those phenomenons not only create inconveniences for us but cost the lives of numerous people; no one wants to know or mention that numbers. We share the same world and the time of sand is running out so we need to know about them so we could prevent them or evacuate the area in time to sustain our precious life. So by knowing they beforehand would give advantages for us to survive in that precise invisible moment. This blog will only explain about The 2004 Earthquake that caused the memorial Tsunami, however there are many other blogs created by my classmates that tells about other various natural hazards.
The day that no one would forget
On 26th December 2004 an earthquake in the Indian Ocean occurred (95.854 E and 3.316 N) (1). It was near the Sumatra Island. It had the magnitude of between 9.0 and 9.3, and it was the largest earthquake since the earthquake in Alaska on March 27, 1964, which had the magnitude of 9.2. So it was a very big earthquake that cost many lives (2). No earthquake occurred in this area before; so many people don’t know that there was going be an earthquake happened. Unfortunately, this earthquake happened in the ocean where there were not a lot people and it does not effect directly to the people.
Tsunami Earthquake: The Great destruction
The epicenter of the eart
hquake was on the west coast of northern Sumatra Island, but it was in the ocean, not on land. This earthquake happened when the two plate’s boundaries slip past each other in opposite direction, creating transform boundaries. The earthquake is very big that it pushes the ocean crust up very strong which makes the footwall move up very fast and huge amount of water were pushes up. As huge amount of water were pushes up, it’s created a huge wave called tsunami, which makes lots of damages to the buildings and people (4). Nevertheless, after the first gigantic wave they comes the second and the third strikes which are more vigorous and actually killing more and more people as they expected it to end. It also deposited sediments and flooded the area for a long period of time creating numerous inconveniences. This earthquake occurred along the Great Sumatran fault, which is on the Indisch-Australlsche plate and the Eurasische plate. As a result, every spot on earth was raised or lowered at least a centimeter (3).
The Ignorant Victims
This earthquake took the souls many lives and confiscated the bodies of unchoosen victims down to the bottom of the sea with them. The act
ual earthquake damaged only the coastal area of the Sumatra Island, but it actually killed a lot of people by creating huge waves called Tsunami. The Tsunami destroyed a lot of buildings and confiscated huge amount of lives in Indonesia, but every country on the coast of the Indian Ocean was also affected. There were about 240,000 people in Indonesia died from the earthquake and the Tsunami. In addition, another 47,000 people died from other countries that have the coast in the Indian Ocean (3). Moreover, some people in the sea (boat) felt the effects and some that are in caves died from the rapid rise of sea level.
The Unpredictable Outcomes
The areas of effect are mostly in Least Economically Developed Countries (LEDCs), Southeast Asia, so poor people who actually have small amount of money have lost all their properties and have to stay in far worst living conditions. The countries that were affected are Thailand, Myanmar, Jakarta, India, Bangladesh, Singapore, Malaysia, Sri Lanka, Maldives and Mauritius. These countries have small amount of facilities and when they were attacked by the wave, almost all the facilities were destroyed and the government can’t replace them in time (also considering the lack of money). They required huge amount of money (which they don’t have enough), maybe from donations, and they also took more time to recover back to normal again. Nevertheless, there were blessing from kind people, who have sympathy, from around the world donated uncountable amount of money for the people who were affected by this disaster which brighten up their hopeless lives.
Why do people live in hazard prone area
As mentioned that the disaster had never happen in this area before so people live in their usual shelters peacefully and not expect anything to happen also because no scientists predict anything to happen. After the disaster their living conditions are worst but they still have to live in their home area and continue their civilized town life because they have no places to go and neither money nor supports.
Protections and Helps
This kind of earthquake and the tsunami had never happened in this area before; so many people does not know what it was and did not get to the safe places in time. There were no warnings, because no one expected that the earthquake and the Tsunami could happen in this area. Moreover, people neglect the dangers and just went out to see what had happened to the sea, for why the water level went low very rapidly. As a result, they could not run in time and died from this disaster (second and third strikes). Now, many countries around this area have the warning alarms, so people would know before the disaster actually happen and could get to safe places in time. There is also the NOAA Pacific Tsunami Warning Center from the U.S.A. to announce the warnings for other countries approximately when and where the earthquakes will occur (5). Right now most of the schools had taught there students about earthquakes and tsunami, and how does it happened. So now many people will be safe from it (6). So no more tear would have to be wasted.
Thank you
