摘要
本文将加卸载响应比理论应用于首都圈地区范围内除唐山、大同老震区以外的中等地震研究,在分析震前地震活动图象的基础上,计算12组地震前响应比的变化。结果表明9组震前响应比值有显著高值变化。通过对响应比起伏变化的时间范围进行统计,寻找首都圈地区中等地震前响应比变化的特点,探索该方法应用于实际中等地震预报的途径。
In this paper the response ratio, a new parameter measuring the instability degree of the crust for a specific region, was applied to the research on the moderate earthquakes in Capital Circle Area (not including the aftershocks of Tangshan and Da-tong earthquakes).Based on analysis of the seismic pattern of 12 earthquakes cases, the response ratios before them were calculated. The result shows that before 9 of the cases, the response ratios have anomalous high-value changes. By analyzing the statistics of the temporal range of the fluctuational change, authors tried to seek the response ratios before the moderate earthquakes and to look for the method to apply it to the practical earthquake prediction in Capital Circle Area.
