摘要
2009年3月28日山西原平M_L 4.5地震的地震序列余震发育,序列多个指标表明本次地震类型为主震一余震型。主震视应力值接近背景水平,推断震中周边地区近期发生更大地震的可能性不大。
The earthquake sequence of Yuanping ME 4. 5 earthquake on 28 March 2009 is developed. Several sequence indexes reveal that the earthquake type is the main shoek-aftershock type. Consequently, the occurrence of Yuanping earthquake indicates that in a future period the North China has the possibility of occurring strong earthquakes.
