The Haiti earthquake occurred at 16:53, 12th of January in Haiti, Dominican Republic. This earthquake happened about 25km west from Haiti’s capital, Port-au-Prince, and nearby town that called Leogane. The epicenter of this earthquake was 18º27'25"N 72º31'59"W. There were also several aftershocks (One that hits after quakes). The earthquake occurred when the Caribbean plate and the North American plate met together. There were no signals on surface or the data of ground formation, so people thought the earthquake will never happen. However, they didn't know the Caribbean plate and the North American plate slipped each other (transform boundary) and caused the big earthquake. Both of them had been locked for about 250 years, gathering stressed together. They slipped together and caused of the big and powerful earthquake.
