摘要
在总结井孔水位异常的中长期、短期(临震)、后效不同阶段特征的基础上,提出三项异常指标:1、水位反向,速率(?)≥-20mm/月,V_(max)≥-40mm/月;2、异常幅度,H≥130mm;3、异常时间,T≥3月。井孔的5次水位趋势异常中,与3次江苏省5～6级中强震和1次南京地区3.1级地方震的对应关系较好,映震能力达0.8,不失为单井预测预报中强地震的一种有效方法而具推广价值。
Based on summary of characteristics of borehole level anomalies of medium, short and postearthquake terms, three anomaly indices are proposed; (1) V and Vmaxof level reverse are ≥- 20 mm/mth and ≥ -40 mm/mth respectively, (2) the anomaly amplitudes H of the level are ≥130 mm, (3) anomaly time T is ≥3 mth. Three of five times of borehole level anomalies respond well to three local earthquake of Ms= 3. 1 in Nanjing area. There- fore, responsive rate for earthquake is 0. 8.
