- Occured on the 12th January 2010
- 7 on the Richter Scale
- In Haiti, 70% of the population live on less than $2 a day
- Haiti sits on a complex strike-slip fault that shares similarities with the San Andreas fault system
- At the fault line the Caribbean and North American plates slide past one another in an east-west direction. Friction builds up until one plate suddenly 'pings' back up.
- In 2008 scientists discovered that the plates which had been moving at an average of 7mm a year since 1751, had become stuck.
- The epicentre was 242m southwest from the capital of Haiti and had a shallow focus of 13km.
- Between 230,000 and 250,000 died - mainly due to collapsing buildings.
- Port-au-Prince (home to 2 million people) was flattened in less than 60 seconds.
- Lateral spreading resulted in ground slumping.
- 50% of buildings collapsed including key government buildings.
- Liquefaction of looser sediments caused building foundations to subside.
- Infrastructure was brought down - the main port subsided, roads cracked and were blocked by debris etc.
- 1.5 million became homeless.
- Damage was localised - a small localised tsunami killed 7 people.
- Strong aftershocks - including a 6.1 magnitude earthquake…
