| 摘 要： | 对新疆北天山地区跨断层流动水准观测资料进行整理,利用断层垂直活动速率求解断层形变异常强度值。基于其变化特征与北天山地区中强地震的对比研究发现,研究区域断层活动整体处于断层形变强度趋势增强的背景下,局部断层形变异常强度值超过指标阈值0.6时,可作为北天山地区中强地震的预测依据。

| Abstract: | This paper reprocessed the cross-fault leveling data of northern Tianshan,calculated the intensity anomaly of fault deformation using vertical movement velocity,comparatively studied characteristics of anomaly intensity changes and moderate-strong earthquakes.The result showed that,the activity of fault movements of study area was under the trends of enhancing fault deformation intensity.It can be prediction evidence for moderate-strong earthquake while the intensity anomaly of fault deformation in partial areas had exceeded the indicator threshold of 0.6. |
