Where: Epicentre was 60 miles off W Coast Northern Sumatra, Indonesia
Time: 7:58 am, 26th December 2004
Scale: 9.0 Richter Scale
Death toll: >230,000 killed or missing
As you can see above, the earthquake hit right beside Indonesia. The 2 plates were subducting under each other, which caused the creation of the Java trench. The Indo-Australian plates is constantly being pushed under the Eurasian plate, but this time it got stuck. The sticking was due to friction, and when released caused an earthquake. But as there was an amount of water that was displaced, so created a Tsunami. This caused the most damage, but the fact there were no disaster warnings in place made it all worse.
It's useful to be able to give a rough sketch of the epicentre and plate margins if you are going to use this case study for the exam!
