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 1 6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 Shantou earthquake precursory observation station using the State Seismological Bureau analysis and forecasting center developed underground fluid integrated digital telemetry system, after 16 months of observation, gas radon, mercury gas abnormalities are outstanding, the measured items more obvious, concentrated to reflect some abnormalities In particular, the anomalous combination of gas radon and gas-mercury anomalies led to a strong correlation with the seismic and stress changes occurring in the NE-trending fault zone along the first line between Nan’ao (NanPeng) and Xiamen (Jinmen Port), and was initially considered as an earthquake Short Pro-precursor anomaly
