Abstract This paper uses the fixed stations of wideband digital seismic waveform data, and calculates the focal shock parameters of the MS4.3 earthquake sequence in Badang county in June 16, 2017. We determine focal shock parameters,including apparent stress, corner frequency and source radius,of 16 earthquakes greater than ML1.8. The relationship between the stress and the parameters is analyzed systematically. Results show that the apparent stress value and the magnitude of earthquakes are positively correlated, the seismic source spectrum of high frequency components is not rich, corner frequency and apparent stress values are far less than the tectonic earthquake, and the underground structure is more complicated in the earthquake source area.
