摘要
对近20年来发生在祁连山中东段的7个中强地震发震时间进行了分析.结果表明:祁连山中东段中强地震基本上发生在节气附近,且多在一个月的上旬或下旬;地震发生前后天气比较冷;地震均发生在太阳活动的峰年或谷年附近.
The origin times of 7 mediumstrong earthquakes in middleeastern section of Qilian mountain seismic zone in last 20 years are analysed. The result shows that: the earthquakes basically occur about solar terms, and in the first or last ten days of a month; the air temperature on epicenter area is colder before and after earthquake; the origin times are coincident with the peak year or the valley year of solar activity.
