focal region

A method is proposed to estimate the stress level in the focal region of an earthquake.

提出了估计地震前后震源区应力水平的方法。

the spatial distribution function of seismicity parameters is determined with the probability of earthquakes in all magnitude level that may occur in the future potential focal region.

以未来各潜在震源区发生各震级挡地震的概率作为确定地震活动性参数的空间分布函数为依据。

In this paper,according to the characters of local seismicity before the event,we pick up some seismological anomalies through Gl spatial scanning,and the focal region is determined.

本文根据震前区域地震活动特征 ,从大区域内提取地震学指标异常信息并通过 GL值空间扫描确定地震震源区 ,取得了较理想的效果。
