摘要
利用形态分析法,分析2015年2月22日沙湾M_S5.0地震和6月25日托克逊M_S5.4地震的前兆数据异常特征。结果表明:沙湾地震发生前,新04泉氢气、乌苏新33井深层水温、榆树沟水管仪、克拉玛依后山2号钻孔倾斜、精河水管仪出现了明显的中短期异常变化,主要表现为数据的高值突跳、阶变、加速变化、年变畸变、矢量打结、反向变化等。托克逊地震前,榆树沟水管仪、库尔勒水平摆出现形态畸变、矢量打结、速率减慢等异常变化。
Take conventional morphological analysis to study precursor anomaly characteristics of Xinjiang Shawan earthquake with MS5. 0 and Tuokexun earthquake with MS5. 4. Results showed there were obvious medium-short term anomalies before Shawan earthquake such as, hydrogen in No. 04 spring, deep water temperature in Wusu No. 33 well,water tube in Yushugou, Houshan No. 2 borehole tilt in Karamay, water tube in Jinhe. The anomaly pattern mainly expressed as high value jumps, stepped change, acceleration, annual change distortion, vector tie and reverse change. Before Tuokexun earthquake,water tube in Yushugou and horizontal pendulum in Korla appeared distotted shape, vector tie and slow rate change.
