摘要: 在回顾昆仑山口西8. 1级地震前的长期、中期的不同阶段不同程度的预测意见基础上,对该次地震前的地震活动进行了分析。结果表明, 该次巨大地震前存在地震条带、地震空区、地震活动增强区、象限性等空间异常及地震活动参数异常, 这些特征对巨大地震的研究与预测具有重要的参考作用。

Abstract: In this paper, based on discussing the prediction results of different stages of long and middleterm before the M8. 1 earthquake in the West to the pass of the Kunlun Mountain, the authors studied the seismic characteristics before this earthquake. The results show that there were many spatial anomalies such as earthquake band, earthquake gap, seismically strengthening area and quadrant, as well as some time-dependent seismic parameters′anomalies before this great earthquake. These characteristics may be of a certain reference significance for the study and prediction of great earthquakes.

Key words: Earthquake in the West to the pass of the Kunlun Mountain, Great earthquake, Seismicity, Quadrant
