兴海及邻近区域2012年1—2月连续发生了24次ML 2级以上地震,该系列地震分布于龙羊峡水库周围。试图通过周边台站记录到的初动信息进行小区域应力场分析,计算了22次地震的震源机制解。通过数据分析,认为龙羊峡水库对邻近区域小地震的震源机制解的特征有一定的影响。
興海及鄰近區域2012年1—2月連續髮生瞭24次ML 2級以上地震,該繫列地震分佈于龍羊峽水庫週圍。試圖通過週邊檯站記錄到的初動信息進行小區域應力場分析,計算瞭22次地震的震源機製解。通過數據分析,認為龍羊峽水庫對鄰近區域小地震的震源機製解的特徵有一定的影響。

Twenty-four ML I〉2 earthquakes from January to February in 2012 occurred in Longyangxia and its adjacent area. The small regional stress field was analyzed by the first arrival information around the seismic stations, the focal mechanism solutions of 22 earthquakes were calculated. The results showed that Longyang- xia reservoir influenced the focal mechanism solutions of small earthquakes.
