The Sagaing Fault is a major fault in Burma, a mainly continental right-lateral transform fault between the Indian Plate and Sunda Plate. It links the divergent boundary in the Andaman Sea with the zone of active continental collision along the Himalayan front. It passes through populated cities of Mandalay, Yamethin, Pyinmana, the capital Naypyidaw, Toungoo and Pegu before dropping off into the Gulf of Martaban, over 1200 kilometers.[1][2] The total slip rate across the Indian–Sunda Plate boundary is about 35  mm/yr, of which 18 mm/yr is accommodated by the Sagaing Fault, according to GPS data.[3] The measured maximum displacement along the fault is about 100 km, although several authors have proposed between 360 km to 400 km.[4]
