| 1 | Study on the Relationship Between Recent Crustal Deformation and the Temporal-Spatial Distribution of Strong Earthquakes (M_s≥6.0) in the Sichuan-Yunnan Region显示文摘Analysis of deformation data measured across the faults, regional vertical deformation data and GPS measurements in the Sichuan-Yunnan region made since the 1980s permitted us to conclude that the crustal deformation in the region during this period of time was relatively weak and caused the occurrence of earthquakes (M S≥6.0), which were not distributed along the major boundary active faults in the region after the 1981 Dawu M S 6.9 earthquake and that the seismic activity is characterized by quasi-clockwise migration. Thus, it follows that earthquake prediction research should be focused on the central part of the Sichuan-Yunnan region in the coming years. Finally, a concept of temporal division of the region into active blocks is suggested and the preliminary result of the division is given in the paper. | LiTieming DengZhihui LüYipei | 2003 | Earthquake Research in China2003，17，4： | 0 |
| 2 | The Recent Crustal Deformation on the Sichuan-Yunnan Rhombic Block Boundaries显示文摘Based on data from an across-fault survey along the Sichuan-Yunnan rhombic block boundaries, the recent deformation characteristics on each fault have been analyzed. It was found that the rate of crustal deformation is slowing down along the northern segment and increasing along the southern segment. Each fault has different features of deformation. The horizontal deformation is mainly characterized by left-lateral strike-slip. The rate of vertical deformation is less than that of the horizontal deformation. The faults have the feature of upper wall uplifting alternated with descending. The anomaly changes of crustal deformation at some sites are closely related to the seismicities near the sites. | Lü Yipei 1), Liao Hua 2), Su Qin 2) and Wang Lan 2) 1)Seismological Bureau of Sichuan Province, Chengdu 610041, China 2)Geodetic Brigade of Seismological Bureau of Sichuan Province, Ya’an 625000, China | 2002 | Earthquake Research in China2002，16，4： | 0 |
