Haiti 發生地震的原因?

地震一般发生在犬牙交错的一块块地壳（板块）间。这些板块相向运动，大部分时间我们察觉不到它们的移动。在这次海地的地震中，加勒比海和北美板块东西相向滑动。这种滑动称为走滑边界压力沿边界各点以及地壳部分粘连的断层增强；最终，压力在强大的运动中突然释放，导致断层的两面移动，引发地震。因破裂而引发地震的断层系，被称为恩里基洛－芭蕉园断层系世界的这部分地区很少见大地震，其部分原因是加勒比海板块较小，其断层系和圣安德烈亚斯不一样长，处在世界最大的板块——太平洋和北美板块之间的边界上。世界的这部分地区很少见大地震，其部分原因是加勒比海板块较小，其断层系和圣安德烈亚斯不一样长，处在世界最大的板块——太平洋和北美板块之间的边界上。

Earthquakes typically occur along the jigsaw-puzzle pieces of Earth's crust, called plates, which move relative to one another, most of the time at an imperceptibly slow pace.

Haiti is located in the Caribbean Plate and the North American plate at the junction of belonging to an earthquake-prone areas. Other parts of the world's most earthquake in a subducting plate to another plate under the lead, but the earthquake was horizontal movement of the two plates of the collision caused by this type of seismic source is usually shallow, and can release a huge energy. The earthquake epicenter is located only about 10 kilometers underground, thus causing great losses.
