摘要:
根据广东潮州井24年的水化学观测资料,通过对强震以及中等地震前水化学异常研究得到,潮州井水化学资料在中等地震前以中短期异常为主,而强震前水化学测项出现长趋势异常变化。研究还表明,同样的震前异常持续时间,未来地震的震中距越大,其震级也应更大。从异常形态对比可见,震中距越小的地震,其异常变化的幅度和速率也较大。
Abstract:
According to twenty four years hydrochemical monitoring data of Chaozhou well in Guangdong Province,we have found the feature of hydrochemical anomaly precursor before the moderate and strong earthquakes.The results show that hydrochemical precursor for moderate earthquakes is short-term and impending anomaly,but the one for strong earthquakes is long-term anomaly.It's also indicated that the forecasted epicenter is larger and the forecasted magnitude is also larger for the same duration of the anomaly.For the abnormal pattern contract,the forecasted epicenter is smaller than the anomaly range and the velocity of variation is larger.
