潮州台地下水化学异常与地震的对应关系

摘要

Based on 6 terms's the observational data of the ground hydrochemistry since 1980 at Chaozhou station,the corresponding relation betwe en the ground hydrochemistry anomalies and earthquakes is concisely discusse d.The result shows that the short-term anomalous changes of all observational te rms except for Cl-before moderate earthquakes occurred within the range of 250 km from Chaozhou station can be observed.%根据潮州台6个地下水测项20年来的观测资 料，对潮州台水化学异常与地震的对应关系作了简要的讨论。结果表明，在距台250 km范围 内发生的中强地震前，除Cl-外，其余测项均观测到短期异常变化。
