【摘要】 采用双差地震定位法对山西省内2001—2005年间发生的ML≥2.0的地震进行了重新定位。重新定位后得到410个地震事件的精确震源参数。结果表明,重新定位后的震中分布呈明显的条带状,且更加集中。定位后的平均震源深度为9.35 km,其中又以地面下2 km~14 km为发震优势层。更多还原

【Abstract】 ML≥2.0 earthquakes occurred from 2001 to 2005 in Shanxi Province are relocated by using double difference earthquake locating method.More accurate focal parameters of 410 earthquakes are obtained by relocating,showing more concentrated and obvious banding distribution of epicenters.The average focal depth is 9.35 km,and 2～14 km underground is the dominate layer where earthquakes can occur more easily.更多还原
