155:(also referred to as the Chixoy-Polochic Fault) lies north and parallel to the Motagua Fault and shares some of the motion between the North American and Caribbean Plates. Studies of GPS displacement of the zone reveal that the motion of the North American / Caribbean Plate Boundary is, for the most part, accommodated by the Motagua Fault.

The measured length of the fault is approximately 350 km and is the longest fault in
Guatemala. Motion of the fault and others in the plate boundary have formed North-South trending
