Abstract:The seismicity anomaly before strong and moderate-strong earthquakes in northern Qinghai--Tibet Plateau is common and credible, it is summarized and analyzed systematically in this paper. It is found that the precursor anomaly parameters of small and moderate earthquake activities before main-shock have a classificational characteristic relationship with the magnitude of main-shock. The result provides practicality and reference to earthquake prediction for this regione.
Keywords:Northern Qinghai-- Tibet Plateau  Classification of seismicity  Anomaly characteristic  Earthquake prediction
