The Three Pagodas Fault is a right-lateral displacement strike-slip fault between Burma and Thailand named after the Three Pagodas Pass. It developed as a consequence of the collision between the Indian and the Eurasian Plate. The Three Pagodas Fault Zone (TPFZ) is a roughly 50 km wide zone separating the westernmost range of the Tenasserim Hills from the Tenasserim coast in Myanmar. The whole area is marked by a great number of fault traces and homoclinal ridges of Paleozoic limestone.
