International audienceWe present the first recorded global positioning system (GPS) data from Myanmar measured at the northern tip of the Sagaing fault. This area is in a very complex geodynamic context, where rigid and semirigid plates interact. The 12 GPS sites measured in 2005 and 2008 in northern Myanmar show that the slip rate is 18 mm/yr and is localized along a single active narrow fault trace (<20 km wide). The same rate was previously demonstrated and remeasured, 500 km southward, in central Myanmar. Despite the geodynamic regional complexity induced by interaction between the Sunda and India plates, the Burma microplate, and the highly deformable eastern Himalayan syntaxis, the slip rate remains surprisingly constant along this fa...
