| Abstract: | It is generally accepted that the Burmese Arc represents a transition zone between the Himalayan collision belt and the Indonesian Arc. The detail analysis of focal mechanism in the Burmese Arc and its vicinity now implicates two dominant factors responsible for the prevailing stress field in the region. The first is the Indian Plate motion, which produces a SSW-NNE compressive stressl the second is the overthrusting of the Eurasian Plate above the indian Plate, which results in a NEE-SWW compressive stress and a tensile stress approximately perpendicular to the main tectonic lines. The flow of material from the deep crust of Tibet to Burmese region facilitates the overthrusting. The two share a common dynamic source, namely, the NNE motion of the Indian Plate. |
