What caused an earthquake?
The shaking started on Tuesday, Jan. 12, at 4:53 p.m. EST in the Haiti region, just 10 miles southwest of Port-au-Prince. The Haiti earthquake occurred at a fault that runs right through Haiti and is situated along the boundary between the Caribbean and North American plates, rocky slabs that cover the planet and fit together like a giant jigsaw puzzle. These two plates constantly creep past one another, about 0.8 inches a year, with the Caribbean plate moving eastward with respect to the North American slab.
