For understanding tectonics and precise earthquake hazard assessment, the detail analysis of hypocenters and moment tensor are necessary. First, present study determined the moment tensor solutions around Myanmar using teleseismic body wave form by the inversion program by Yagi. Moment tensor solutions obtained in this study are almost consistent with the global CMT solutions. The general orientations of P-axis for shallow earthquakes are consistent with the NNE direction of the Indian plate motion with respect to the Eurasian plate. Next, we relocated hypocenters in and around Myanmar, using the modified joint hypocenter determination (MJHD) method developed by Hurukawa and Imoto. This technique allows us to relocate many events simultaneously in order to improve hypocenter location compared with ISC hypocenters; the MJHD method gave the surprisingly clear features of seismicity. Along the Burma arc, the hypocenters are concentrated on narrow inclined zone. The results show the configuration of the subduction zone. Also we clarified the features of seismicity along the inland fault zone. The Sagaing fault system is located at the area where the cut-off depth of seismicity becomes shallower and the strength of the crust is weaker. Furthermore, we found that the earthquakes are concentrated on the active spreading axis and transform fault in the southern opening region. The results give us new constraints on understanding tectonics in and around Myanmar.
