| 摘 要： | 通过双差定位法，对江苏及邻域1990-2012年地震事件进行重新定位，其中包括部分人工爆破和塌陷事件。结果显示，重新定位后的爆破和塌陷事件震源深度均有明显改善；地震在空间分布上更加集中，部分地震有向构造带趋近的变化，较多地震呈丛集状出现，震源深度主要集中在5-25 km范围内。

| Abstract: | The earthquakes,includeing artificial blasting and collapse,occurred in Jiangsu area and adjacent region from 1990 to 2012 were relocated with the double difference algorithme.The result showed the all of relocated depth of artificial blasting and collapse events had the dis-tinct improvement.The spatial distribution of earthquake is more centralized,while the earthquakes in a part of areas get close to tectonic belts,many earthquakes occurred in clus-ter.The depth of earthquakes mainly concentrates in 5-25 km scopes. |
