| 摘 要： | 利用双差地震定位法对豫北及邻区1985—2008年的787次地震进行重新定位，得到了497次地震定位结果。结果显示：重新定位后震中呈条带状丛集分布，部分地区地震向构造带趋近；震源深度主要分布在上地壳和中地壳内，平均深度13.3 km，10～20 km为多震层深度范围。

| Abstract: | The earthquakes that occurred in the area of Yubei and adjacent region from 1985 to 2008 were relocated with the double difference method and the results of 497 earthquakes were obtained. The result shows that the distribution of relocated epicenters appear zonal,while the earthquakes in a part of areas get close to tectonic belts. The most hypocenter depths in the area distribute mainly within the upper and middle crust. The average hypocenter depth is 13.3 km and the seismogenic layer ranges from 10 km to 20 km. |
