Why was it so bad?

- Haiti hasn't got strict building regulations, many people were crushed inside buildings due to the pancake effect

- Loose sediment amplified the seismic waves

- Lack of building regulations

- LEDCs like Haiti cannot afford earthquake predicition equipment

-Soft sand of the river basin caused many structres to fall into the river and harbour

- Lack of steel rods in the building structure caused the conrete to crumble and buildings to collapse
