Introduction:



Humans live on unsteady ground. This fact was
made abruptly apparent on January 12, 2010, when
a magnitude 7.0 earthquake devastated the Caribbean
island nation of Haiti. Because many buildings in this
impoverished country were poorly constructed, they
could not withstand the shaking and collapsed en masse,
particularly in the capital city of Port-au-Prince, 15
miles from the quake’s epicenter. Rescue workers desperately
combed through rubble, hunting for survivors.
By early February, Haiti’s prime minister estimated
that more than 200,000 people had been killed by the
earthquake’s effects. This type of earthquake, caused by
two separate sections, or plates, of the Earth’s crust
sliding against each other is known as a strike-slip
earthquake. It is just one example of the restlessness of
Earth’s surface.
