Sagaing Fault


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. The total displacement 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. Different segments of the fault ruptured in May-1930, Dec-1930, 1931 and 1946. The fault ruptured in 1930, causing a Magnitude 7.3 quake and likely a local tsunami at Bago, causing over 500 deaths.
