Question

The map shows the movements of internally displaced persons (IDPs) out of Port-au-Prince, Haiti, following the earthquake of January 2010.

[Source: adapted from Internal Displacement Monitoring Centre (IDMC). www.internal-displacement.org]

Estimate the number of internally displaced persons (IDPs) moving to Artibonite.

[1]
a.i.

Estimate the furthest distance, in km, from Port-au-Prince at which very strong earthquake intensity was experienced.

[1]
a.ii.

Outline how the distance from the epicentre of an earthquake can determine the severity of two associated secondary hazards.

[4]
b.

Explain two reasons why internally displaced persons may have to wait a long time to return home after a major earthquake event such as this.

[4]
c.

Markscheme

125 000 persons (accept 100 000–150 000).

a.i.

80 (allow 70–90).

a.ii.

In each case, award [1] for recognizing a valid secondary hazard, and [1] for further development showing applied knowledge of geophysical hazards.

For example: The further from the epicentre, the fewer landslides [1]. This is because shaking is less severe, which can cause instability of slopes [1].

Do not double credit less severe / more severe shaking

Other possibilities include:

b.

In each case, award [1] for a valid reason and [1] for further development showing applied knowledge of geophysical hazards.
