Haiti Earthquake January 2010 Haiti – background

• Haiti is in the Caribbean and is the western third of the island of Hispaniola – joined by the Dominican Republic

• Has a population of 9 million people• Port-au-Prince is the capital with a

population of 3.5 million • It is the poorest country in the western world

– more than half the population live on less than $1 a day

Why did it happen?Causes:

• Haiti is situated along the boundary between the Caribbean and North American plates

• These two plates move at about 20 mm a year, with the Caribbean plate moving eastward while the North American plate moving west.

• It is a conservative plate boundary. • This movement is not smooth and there is friction between the

North American Plate and the Caribbean Plate. • Pressure builds between the two plates until it is released as an

earthquake.
