Tectonics or Vulnerability. Which caused the Boxing Day tsunami 2004 to be the disaster that it was?


geog blog #4


 When you type into Google ‘boxing day tsunami 2004’ you receive 649,000 results in 0.31 seconds.  Trying to figure out what happened to achieve global coverage like this is a near impossibility. At what point does a natural hazard become a natural disaster? At what point does a minor issue become a worldwide problem? At what point does the level of development in the countries affected, become a global priority that needs to be addressed? Trying to answer these questions requires a full analysis of the events that occurred on the 26th December 2004.

There are over 7 billion people in the world and the theory ‘6 Degrees of Separation’ suggests that by a chain of ‘friends of friends’ people could be connected by 6 people or fewer. Despite this the further the two people’s lives are the less likely these connections become.  Therefore when the Boxing Day tsunami happened, proportionally is seems unlikely that if you are living in a developed and Western country far from the troubles of the Pacific that you would know anybody. However the same cannot be said for the people who live there. How can one person not know a single person directly affected and yet another only know people directly affected.

Of course when looking at the number of people affected we are not looking only at those who felt the water and have the strap line  ‘I survived the 2004 tsunami’ with them forever, but also those who are affected by a chain of connections, those people who sit at the very long end of a domino effect and still suffer. The best way to demonstrate this is with my own story; I came from living in Hong Kong and assumed that I would never be part of a vulnerable population, I was wrong.

‘Thailand 2004 The day the water came’.
8.30am: between ordering and the food arriving my sisters and I had run down to the beach to play and pass the time, of course we came back exclaiming about how the beach had grown. Being aged 9, 6 and 4 we were blissfully unaware that the unusually low tide was not something to be excited about but rather was a death trap waiting to happen.

9am: myself, Christie and Kitty were in ‘Kids Club’ drawing, colouring in Aboriginal masks, once Kitty had exhausted all of the fun to be had she asked to return back to Mummy and Daddy, Christie obliged and took her back to a cafe on the beach front  The cafe and the Kids Club ran parallel to the sea along the back of the beach.

Once we had returned to the Kids Club this was the moment that everything changed, ‘RUN.RUN.RUN’ scream the ladies in the kids club, as I look over the small wall, about a metre high I can see the wave, the wave filled not only with water but with screams, debris, and people. As the wave continues to flood in it breaks the barrier designed to keep children in rather than tsunamis out. The kids club lady pushes open a door at the back of the room which reveals a staircase, designed to be used in emergencies leading up to the first floor reception area. The ladies are grabbing children with as many limbs as they can manage and try to collect us all on the stairs.

9.45am: Christie and I are standing in the open fronted lobby looking down at the beach, the restaurant and the mass of people and furniture. We can see what is left of the beach cafe but all we can do is scream at the top of our lungs ‘come to the lobby’. Parts of a traumatic event will stick by you forever and that sentence which I shouted until my lungs had no more air will never leave me. I looked around and all I could hear is screaming. Not the type of screaming when you break a bone or stub your toe. Not the screaming when somebody jumps out and scares you. This is the screaming of confusion and chaos. Nobody is sure of anything, people, places even the direction they are facing.

Suddenly I see my mum running towards us, and in a way that only a mother’s hug can, I was re-assured and I knew that everything would be alright. She told us to sit on the sofa in the lobby and not move whilst she went to find Kitty and my dad. Christie asked me, what had happened, being only 9 I struggled to come up with an answer, however Christie being 7 believed my response as if it were completely true. ‘The Moon and the Sun have had a fight, because the Sun gets to be in the sky during the day when everyone can look at it but the Moon only gets to be in the sky at night when everyone is sleeping. They had a fight and the Sun won, so he pushed the Moon into the sea and it made a big wave.’ Highly unlikely but in the state of confusion anything goes.

It was soon after this that my mum, accompanied by my dad and Kitty came running up the stairs and the family to be re-united. The minutes and hours that directly followed these events all seem a blur. Its hard to remember the calm after the storm and therefore remembering the aftermath of the tsunami is challenging. We were staying in inter-connecting rooms and at a time we were prepared to give up one of our rooms to allow guests without accommodation to have somewhere to call home. We then found out that it wasn't even necessary, the number of guests in the hotel had inevitably decreased.

In the hours that followed anxious guests spoke to the management to try and get whiteboard with information on and bottled water and other food from the first floor store rooms. It was like being an evacuee, there were rations and when your rations had gone that was it. There was no longer a state of panic but a state of uncertainty  with no electricity and no geophysical scientist the origin of the disaster we had just experienced and the possibilities of recurrences were all completely unknown. Thats the story that changed by life, the story that has left me with the strap line ‘I survived the 2004 boxing day tsunami’ and the story that affected millions of people worldwide. ‘


That day and in the days that followed across 14 countries in the Pacific more than 230,000 people were killed. The most devastating effects were felt in Indonesia where officially 131, 028 deaths were recorded however the un-official number could be significantly more. There are a number of factors that affect the vulnerability of a population when looking at tsunami’s. These would include distance from the sea, and the epicentre that sparked the tsunami, level of development i.e. a large building vs. a beach hut, the access to warning systems so that evacuation plans can be implemented, and the finally the people affected. The disaster risk-equation is equalled out to hazard multiplied by vulnerability and then divided by capacity to cope.

The vulnerability of these populations were high, and needless to say that prediction and management strategies were basic if not non-existent, furthermore a combination of the population and tectonics must be held accountable for the events of that day. Needless to say that human beings live in a progressive society, where steps are taken to protect populations in the future and therefore the possibility of a repeat of my story is unexpected. Saying that the planet is an uncontrollable and complex place and as inhabitants of this bizarre land all we can do is prepare for changes and embrace the natural experiences that will be thrown our way.

Hurricane Sandy

geog blog #3

Hurricane Sandy is being described as the worst storm to hit the USA in recorded history. The hurricane brewed in the Atlantic Ocean to the East of the USA on the 22nd October 2012 It affected 24 states particularly New Jersey, Pennsylvania, Maryland, Delaware and New York as well as Vermont and areas of Canada.

http://www.bbc.co.uk/news/world-us-canada-20137363

In New York City (the largest city to be affected) all subways were been closed for 3 days and all public transport suspended. President Obama urged the individuals who were affected to 'take it seriously' already 400 000 New York citizens were evacuated in anticipation of the events that were to follow.  

The storm's effects include the cancellation of the New York Marathon which was set to take place this weekend. It was decided that it would be ridiculous to be handing out free bottled water to the runners when there are individuals living in New Your who have no access to clean water and in some areas no power. Early calculations suggest that Sandy caused the following damages:  

CountryFatalitiesMissingDamage (in USD)Sources
 United States1101$50 billion (estimated)[152][153][154]
 Haiti5421Unknown[155][156]
 Cuba110$80 million[152][157]
 Bahamas20$300 million (estimated)[152][158]
 Canada20Unknown[159][160]
 Dominican Republic20Unknown[152]
 Jamaica10$55.23 million (estimated)[152][161]
 Bermuda00Unknown[152]
Total18222>$50 billion (estimated)


Where this information and the events that occurred are potentially interesting is looking at whether the storm would have had the affects that it did and would have been the magnitude that it was if it wasn't partly sue to global warming and the rapid development of global populations. The individuals who were affected could be classed as a vulnerable population, many areas such as Manhattan are low lying and therefore very susceptible to flooding and storm surges. As well as this the fact that the land is so built up and industrial does not aid the natural removal of water. Water is not able to sink into the ground and flow as groundwater flow but rather it contributes to surface run off and the flooding.

Then global warning, are the frequency and magnitude of hurricanes increasing over time? Hurricane Sandy was the tenth largest Atlantic hurricane on record. Hurricanes form when the warm water is sucked up into a channel which has rotational force due to the Coriolis effect. If water is warmer then more will evaporate and be picked up into the hurricane causing the size to grow. Whilst the link between global warming and hurricanes may be tenuous it cannot be ignored.

Hurricane Sandy came and went over an October half term but for some people it will never be forgotten.
