Mercalli Intensity Scale below, on the Haiti Earthquake Intensity Map in your answer booklet, and on your
knowledge of Earth science. The map shows the location of Haiti in the Atlantic Ocean. The Modified Mercalli
Intensity Scale describes the amount and type of damage caused by an earthquake on a scale from I to XII.
A portion of this scale is shown below. Modified Mercalli intensity values for the January 12, 2010, earthquake
in Haiti are represented on the Haiti Earthquake Intensity Map in your answer booklet.
