Haiti is located on the Caribbean Plate, specifically on the northern boundary of the plate, which is a transform fault boundary with the North American Plate.

Here's a breakdown:

* Plate Boundaries: The Earth's outer layer (the lithosphere) is broken into large, moving pieces called tectonic plates. These plates interact at their boundaries, creating various geological phenomena.

* Transform Fault Boundaries: These boundaries occur where two plates slide past each other horizontally. This type of boundary is responsible for earthquakes, but not volcanic activity.

Haiti's location on a transform fault boundary means it is vulnerable to frequent and sometimes devastating earthquakes.
