Abstract This paper used Snoke method and cap method to inverse the focal mechanism solutions of the 14 earthquakes from August 2014 to March 2015, and analyzes the temporal and spatial changes. At the same time, we calculate the 14 ML≥3.0 earthquakes by the PTD first arrival method, and compare the results with CAP depth search method. The results show that the 2014 Jinzhai earthquake swarm sequence is densely distributed between 115.50°-115.53°N, 31.50°-31.53°E, with no obvious seismogenic law in the time and space. The focal mechanism solutions of the 14 ML≥3.0 earthquakes are basically the same, the azimuth of P axis is relatively consistent, and the dip angle is relatively high. It’s a strike-slip earthquake under the action of horizontal compression near EW direction and horizontal tension near NS direction. The results obtained by the two methods are similar, focusing on 2 to 5 km.
