| 摘 要： | 采用河北测震台网资料,分析了张家口—渤海地震带2008—2018年1220条ML≥2.0地震的应力降。结果表明,应力降可能与应力有关,并且随震级的增加而出现不同尺度的变化,该区域应力降优势分布为0.70—3.00 MPa。

| Abstract: | Based on the data of the Hebei seismic network, the stress drop of 1 220 ML ≥ 2.0 earthquakes in the Zhangjiakou-Bohai seismic belt from 2008 to 2018 is analyzed. The results show that the stress drop may be related to the stress and vary in different scales with the increase of earthquake magnitude. The stress drop in this area is mainly distributed between 0.70 to 3.00 MPa. |
