摘要: 汕头市地震前兆观测站使用国家地震局分析预报中心研制的地下流体综合数字化遥测系统,经16个月的观测,表明气氡、气汞异常突出,各测项较明显、集中地反映一些异常,特别是以气氡、气汞异常为先导的异常组合与南澳(南澎)至厦门(金门港)一线NE向断裂带及其附近发生的地震及应力变化相关性较强,初步认为是地震短临前兆异常。

Abstract: By using the instrument of synthetic numerical remote measurement, the seismic precursor observation station of Shantou city has conducted the observation of underground liquids for 16 months. The observational results show that the anomalies of gaseous Rn and Hg are quite remarkable and other observational items also show the obvious and concentrated changes. Particularly, the anomaly combinations guided by anomalies of gaseous Rn and Hg show close correlation with the seismic activity and stress changes occurred along NE-striking Nan’ao (Nanpeng)-Xiamen (Jinmen Port) fault and its adjacent region, which is preliminarily considered as short-term and imminent earthquake anomaly.
