The
Sagaing Fault is a major
fault in
Burma, a continental transform fault between the
Indian plate and
Sunda Plate that connects spreading centers in the
Andaman Sea and the continental convergence zone 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.
Global Positioning System campaigns revealed a right-lateral slip rate of 18 mm/yr. 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.
