青藏高原北部中强以上地震震兆异常的分级特征研究

Research on Characteristics of Earthquake Activity Classification before the Strong and Moderate-strong Earthquakes in Northern QinghaimTibet Plateau

摘要:

通过对青藏高原北部中强以上地震前普遍出现的地震活动异常进行了系统的分析和总结,发现各地震活动前兆异常参数与主震震级有分级特征,其结果对未来青藏高原北部中强以上地震的预测具有一定的实用和参考价值。

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.
