【摘要】 本文用水平摆倾斜仪实测记录资料,研究了1976年4月6日内蒙古和林格尔6.3级地震临震期的地倾斜波动现象。波劫是在地震发生前15小时开始的。这种波动现象可能是由震源在临震期向源外辐射的一种能量引起的,波动的方向性很强,面向震源区。它有可能是一种地震前兆,对临震予报有参考价值。更多还原

【Abstract】 Using the data observed by horizontal pendulum tiltmeters, this paper studies the fluctuation of ground tilting for imminent term before Helingeer earthquake 6.3 of April 6, 1976 in Nei Monggol Autonomous Region, China. The fluctuation, which began fifteen hours before the seismic event, may be that a energy radiated out from the hypocenter area before the earthquake should immediately occurs. The fluctuation of ground tilting observed by the tiltmeters is a stable, directionsense movement pointing to the hypocenter area. Thus this phenomena is a precursor of earthquake as one of basis of predicating imminent earthquake.更多还原
