【摘要】 运用mapsis软件前兆异常分析中的差分、从属函数等计算方法对新10号泉硫化物测值进行异常识别。结果表明:(1)差分和从属函数异常以高值异常为主;(2)差分异常对应近场MS≥5地震对应率为100%(6/6),对远场MS≥7地震对应率为66.7%(4/6);(3)差分和从属函数异常最大量对近场MS≥5地震的震级和震中距相关性不明显;(4)差分和从属函数异常有一定同步性。更多还原

【Abstract】 Using difference,subordinate function methods in Mapseis soft to analyze the abnormal change of sulfid in New No.10 spring,the result shows,(1)the abnormal shape is high value anomaly;(2) the difference abnormity is high value for the earthquakes with MS≥5 in the near region,low value for the earthquakes with MS≥7 in the far region;(3)the relation between max-value of abnormity and magnitude,epicenter distance of MS≥5 earthquakes is not evident;(4)there is certain synchronicity between difference and subordinate function abnormity.更多还原
