It accommodates more than half of the 16 right-lateral motion between Sundaland and India, within the diffuse plate boundary along the eastern 17 margin of India, which occupies much of Myanmar (e.g. Vigny et al. 2003; Nielsen et al. 2004; 18 Socquet et al. 2006) (Fig. 1). Acting as a ridge-subduction transform (Le Dain et al. 1984; Guzmán- 19 Speziale & Ni 1996; Yeats et al. 1997), the 1500 km long Sagaing Fault links major thrust systems in 20 the north, such as the Naga, Lohit and Main Central thrust zones near the eastern Himalayan syntaxis, 21 to the Andaman Sea spreading centre in the south (e.g. Win Swe 1970; Le Dain et al.
