【摘要】 2011年5月1日哈萨克斯坦境内发生MS5.2地震,震前部分哈萨克斯坦地下流体测项出现了前兆异常。通过分析,总结出其异常类型大致有2种:①波动异常,主要表现为速率变化、上升幅度超出正常波动范围;②年变畸变异常,主要表现为打破年变规律。此次地震前中短期异常的出现时间与震中距成正比关系。更多还原

【Abstract】 Underground fluid in Kazakhstan appeared precursor anomaly before Kazakhstan earthquake with MS5.2 occured on May 1st,2011.The anomaly type can be divided into two types: ① wave anomaly which is mainly presented as rate change or rising range transfinite;② distortion anomaly which mainly presented as broken yearly change law.The appearance time of mid-short term anomalies before earthquake is proportional to epicentral distance.更多还原
