What caused a tsunami?
- When most people think of tsunamis, images of ground-rattling earthquakes usually follow.

- Movements in the ocean crust can displace the overlying chunk of water causing waves to pile up and crash into nearby shores.
- In this case, the most likely culprit is Anak Krakatau.
