| 摘 要： | 1991年2月25日柯坪6.5级地震前,震中附近地区的土层地应力、金属摆倾斜仪等多项前兆观测出现异常变化,说明强震发生前近场灵敏度较低的简陋仪器也能观测到明显的前兆反应。分析、认识这些异常对地震短临预报的决策是有益的。

| Abstract: | Just before Keping 6. 5 earthquake that happened on Feb. 25,1991, some obvious abnormal variations were found on several precursory observational instruments that installed near the epicentre area. According to the anomaly on solum stress, pendulum tiltmeter etc. , we could see that the low sensitive simple instrument of near-field can also capture the very important and obvious precursors. So to get to know these anomalies is very useful in short term and impending earthquake prediction. |
