By comparing the response characteristics and seismic phase parameters recorded by VP, SSQ second sampling tiltmeter and JCZ-1T seismometer in the same period of the earthquake, this paper presents that the three instruments can all record clear P wave, S wave and surface wave, and S wave recorded by VP and JCZ-1T is clearer than that recorded by SSQ. Bandwidth of seismic waves recorded by VP is more consistent with that of JCZ-1T records. Before the Iran and Pakistan boundary M7.7 earthquake on April 16, 2013, JCZ-1T seismometer and SSQ tiltmeter simultaneously record a slowly moving event at intervals of 15~30 s.
