This article integrates traditional seismological methods with digital seismological methods,reviews and summarizes the work of the Jiuzhaigou M_S7.0 earthquake in our daily analysis and forecast work. The anomalous information is summarized before the earthquake in southeast Gansu. Some mid-and short-term and impending earthquake anomalies related to the occurrence of this earthquake are also combed. The seismic activity images of different magnitudes in the area before the Jiuzhaigou M_S7.0 earthquake are analyzed. It is found that the M_S5.0 seismic quiescence in the western region of China is contracted to the epicenter before the earthquake. The super long calm time of the M_L4.0 seismic quiescence reaches 458 days and the M_L3.0 seismic gap is broken in 4 days before the earthquake. At the same time,the focal mechanism in the vicinity of the epicenter is highly consistent,which reflects the high stress level in the focal region. The research work does not only explore the potentially regular occurrence of this earthquake,but also provides a more valuable experience and methods of reference.
