并使用网格搜索和模拟退火方法反演海原断带滑动速率和锁紧程度的GPS数据。

by comparing different block models, the Haiyuan block should be considered independently. The Haiyuan fault zone adjusts surrounding block movements and uplifts Liupanshan mountain tectonically. The results can provide important references for understanding the regional earthquake risk and deformation mechanism.

Aiming at the differences in the slip rate and locking degree obtained from different studies, and Haiyuan blocks rotate clockwise,武汉大学刘洋团队研究了基于精细块体模型和GPS数据的青藏高原东北部海原断裂带滑动速率和锁定程度。

The results are as follows: (1) The sinistral slip rates in the western, 本期文章:《大地测量与地球动力学》:Online/在线发表 近日,(3)冷龙岭、金强河、毛毛山和六盘山断层的滑动赤字相对较高(20公里内平均约为3.42 mm/a、4.16 mm/a、4.23 mm/a和3.43 mm/a), 结果表明:(1)西段、中段和东段的左旋滑动速率分别为4.93-5.22 mm/a、1.52-4.94 mm/a和0.43-1.18 mm/a, northeastern Qinghai-Xizang plateau, while the compression rates are 0.451.26 mm/a。
