哈萨克斯坦博古特2604号井水位异常特征初步研究
PRELIMINARY STUDY OF WATER LEVEL ABNORMITY CHARACTERISTIC IN NO.2604 WELL OF BOGUTE IN KAZAKHSTAN
【摘要】 根据博古特2604号井近15年的水位资料变化情况,以井距500 km为扫描半径,对在其范围内发生的中、强地震和水位资料的变化进行了较为详细的分析。该井在其映震范围内的5级、6级和7级地震前水位各有不尽相同的异常显示特征,随着震级的减小,震中距的增大,异常特征由长时间的年变异常或不稳定的下降、上升转为短期的阶段性的上弯高值异常,直至异常消失。由于博古特井特殊的地理位置,其对南北天山发生的地震在震前都有较为良好的反映。
【Abstract】 According to the data change of water level in No.2604 well about 15 year,taking 500 km away from the well as the scanning range,we analyzed in detail mid-strong earthquakes and the data change of water level in the range.The water level of the well appears different abnormity characteristics in the corresponding scope for earthquakes with M5,M6 and M7.With the magnitude reduction and the enlargement of epicenter distance, the characteristic of the abnormity changed from the annual variation of the long time or the unstable drop and the rise abnormity to the rise-bend high value abnormity of the phase of the short-term,until it disappeared.Because of the special geographical position of the Bogute well,it has very good reflection before the earthquakes occurred in north and south Tianshan mountain.
