【Abstract】 Based on the data of the first motion of P-wave from the more than 2000 earthquakes with M L≥2 0 occurred in Kunming basin and its adjacent areas,the regional tectonic stress field and the forming model of Kuming basin are analyzed.The forming,evolution and developing tendency of Kumming basin are put forward based on Cenozoic strata and the pattern and time of faults in Kunming basin.更多还原
