A new method about measurement of the precursory infrasonic waves of strong earthquake was introduced.

It is suggested that the swarm might occur frequently and was not a precursory one.

The generating and propagating mechanism of the precursory infrasound of earthquake are primarily explained.

During the friction period, there is no precursory increasing of AE activity before the big stick-slip events.

Thus animals may have the means and sensitivity to sort out and discriminate the threatening precursory signals of an impending earthquake, thus activating a behavior pattern for survival.

The results show that from the analysis, anomaly information before the main shock could be recognized and the precursory anomalies before Xinzhou M5.1 earthquakes in1991 is significant.

The maximal amplitude of the precursory infrasound is related to the magnitude of earthquake and the distance and depth of the epicenter.

For the other 5 main shocks, the simulation cannot be made due to the insufficient precursory events for the full determination of energy accelerating curve or disturbance to the energy release curve.
