Abstract
In the article, we have used CAP method and local broadband waveform data to determine the focal mechanism of Milin M 6.9 earthquake in Tibet on Nov.18, 2017. The result shows that the best double couple solution of the M 6.9 event is 285°, 47°, 70°for strike, dip and rake angles respectively. The other nodal plane is 133°, 46.6°, 110.1°; The estimated focal depth is about 19.0 km. The result shows that the event is thrusting and minor strike slip earthquakes, one strikes of the two nodal plane are same to strike of Jiali-Chayu fracture. At the same time, the spatial distribution of aftershocks is consistent with fault strike.关键词
