EARTHQUAKE ANOMALY ANALYSIS OF YONGNING COUNTY AND LINGWU CITY BASED ON THE RADON DATA OF XIAOKOUZI SPRING AT YINCHUAN STATION
【摘要】 水氡作为一种重要的前兆观测手段在地震预报中有重要意义。银川台小口子水氡自1978年6月投入观测以来,其年变规律呈现夏高冬低的形态,通过水氡值变化分析发现,其对宁夏永宁县、灵武市4.5~5级以上地震震前大多数有一定的反应。
【Abstract】 The water radon,which is an important precursory observation method,can provide us with useful information to forecast earthquakes.The water radon has been used to monitor precursory changes since June,1978,its normal annual variation is high in summer and low in winter.Through analyzing the water radon relative variation before most of the Yongning and Lingwu earthquakes,we observed the abnormal relative changes.
