| 1 | The Late Pleistocene activity of the eastern part of east Kunlun fault zone and its tectonic significance显示文摘The nearly EW-trending East Kunlun fault zone is the north boundary of the Bayan Har block.The activity characteristics and the position of the eastern end of its eastward extension are of great significance to probing into the dynamic mechanism of formation of the east edge of the Tibetan Plateau,and also lay the foundation for seismic risk assessment of the fault zone.The following results are obtained by analysis based on satellite image interpretation of landforms,surface rupture survey,terrace scarp deformation survey,and terrace dating data on the eastern part of the East Kunlun fault zone:(1)the Luocha segment is a Holocene active fault,where a reverse L-shape paleoearthquake surface rupture zone of about 50 km long is located;(2)the Luocha segment is characterized by left-lateral slip movement under the compression-shear condition since the later period of the Late Pleistocene,with a rate of 7.68–9.37 mm/a and a vertical slip rate of 0.7–0.9 mm/a,which are basically in accord with the activity rate of segments on its west side.The results indicate that it is a part of eastward extension of the East Kunlun fault zone;(3)the high-speed linear horizontal slip of the nearly EW-trending East Kunlun fault zone is blocked by the South China block at east,and transforms into the vertical movement of the nearly SN-NNE trending Minjiang fault zone and the Longmenshan fault zone,and the uplift of Longmenshan and Minjiang.The area where transform of the two tectonic systems occurred confines the position of the east end;(4)Luocha segment and Maqu segment constitute the'Maqu seismic gap',so,seismic risk at Maqu segment is higher than that at Luocha segment,which should attract more attention. | ZHANG JunLong REN JinWei CHEN ChangYun FU JunDong YANG PanXin XIONG RenWei HU ChaoZhong | 2014 | Science China Earth Sciences2014，57，3： | 8 |

| 3 | Surface Rupture and Coseismic Displacement of the M_S7.1 Yushu Earthquake显示文摘On April 14,2010,a devastating earthquake measured 7.1 on the Richter scale struck Yushu county,Qinghai Province,China.Field geological investigation and remote sensing interpretation show that this earthquake generated an inverse 'L-shaped' surface rupture zone,approximately 50km long.The surface rupture zone can be divided into three segments.Between the northern and middle segments of the surface rupture,there is a 16km-long segment,where no rupture was observed.The middle and the southern segments are arranged in a left-step manner,and there are right-step en echelon ruptures developed in the stepovers.The seismogenic structure is the Yushu fault,which is dominated by strike-slip with a small amount of thrust component.The earthquake results from the differential movements between the southern Qiangtang Block and northern Bayan Har Block.The earthquake recurrence interval is 185a^108a.Along an approximately 20km-long part of the Garzê-Yushu fault,between the southern surface rupture of Yushu MS7.1 earthquake and the 1896 earthquake,there is no surface rupture,its seismic risk needs further research. | Zhang Junlong Chen Changyun Hu Chaozhong Yang Panxin Xiong Renwei Li Zhimin Ren Jinwei | 2011 | Earthquake Research in China2011，25，2： | 2 |
| 4 | A Preliminary Study on a Seismotectonic Model for the Active Faults in the Xining Urban Area显示文摘On the basis of the Xining active urban fault survey,we studied the relationship between the active urban fault and fold deformation.The result of this research shows that the Huangshuihe fault and the NW-striking fault on the northern bank of the Huangshuihe River are tensional faults on top of an anticline,the Nanchuanhe fault is a transverse tear fault resulting from differential folding on two sides of the fault,the east bank of the Beichuanhe River fault is a compressional fault developed on the core or climb of a syncline.By balance profile analysis of fold deformation and inversion of gravity anomaly data,we obtained the depth of the detachment plane and established the seismotectonic model of the Xining urban area.Based on the seismotectonic model,we analyzed the earthquake potential of the active urban fault. | Tian Qinjian Li Zhimin Zhang Junlong Ren Zhikun | 2008 | Earthquake Research in China2008，22，1： | 2 |

| 9 | Characteristics of Late Quaternary Activity of the Gadê Segment in the Madoi-Gadê Fault Zone显示文摘Madoi-Gadê fault is an active fault in the Bayan Har block.According to field investigation,there is an earthquake surface rupture fairly well preserved on the Gadê segment of the Madoi-Gadê fault zone.The length of the rupture is approximately 50km,with a general strike of NW.The maximum horizontal sinistral displacement is about 7.6m and the maximum vertical displacement is about 4m.A large number of earthquake traces are to be found along the rupture zone,and the phenomena on the surface rupture are also various.Field investigation and analysis on the geological and geomorphological phenomena show that the formation age of the surface rupture is relatively young.A series of linear arranged,triangular facets,fault scarps,fault springs,dislocated gullies,twisted mountain ridges,sag-ponds,dislocated ridges,etc.exist along the fault.Based on the analysis of field investigation and the data available,we believe that the surface rupture is due to a strong earthquake in the history of this area.And it is inferred that the Madoi-Gadê fault within the Bayan Har block has been highly active since Late Quaternary and may still be active nowadays. | Xiong Renwei Ren Jinwei Zhang Junlong Yang Panxin Li Zhimin Hu Chaozhong Chen Changyun | 2011 | Earthquake Research in China2011，25，2： | 0 |
| 10 | Earthquake Surface Rupture Features and Tectonic Significance of the Tazang Fault in the Eastern Part of the East Kunlun Fault Zone显示文摘The East Kunlun fault zone is located in the northern margin of the Bayan Har block. The study of earthquake rupture behavior in the fault zone is of importance for understanding the future seismic risk in northwest Sichuan. A number of geological field investigations, typical micro topography DGPS measurements and sample dating show that the earthquake activity of the East Kunlun fault zone extends to the north boundary of Zoige basin, a segment known as the Luocha segment of Tazang fault. In the satellite image, the segment is seen clearly as gray and yellow strips. The earthquake deformation zone mainly features fault scarp, valleys on the slope, offset gullies and terraces, linear distribution of plants, waterfall, fault spring, fault sag pond, and landslide, collapse and talus associated with surface rupturing. These phenomena are distributed intermittently along the re-existing fault and form a ~50km-long inverse L-shaped deformation zone. Fault activities caused left-lateral offset of gullies and terraces, with horizontal displacement concentrated at 5.5m^6m, 18m~23m, 68m~75m, and 200m~220m, respectively. The recent earthquake occurred between 340±30~500±30BP. The macro epicenter is located 5km~7km northwest of Benduo village, with magnitude of MW7.3~7.4, maximum coseismic displacement of 6m, horizontal displacement 5.5m~6m and vertical displacement 0.2m~0.5m, being in a proportion of 5∶1~10∶1. These phenomena show that the Tazang fault is the causative fault of this earthquake. The fault is a Holocene active fault and was dominated recently by left-lateral movement with a small amount of thrust component under compressive shear stress. This characteristic is similar to the movement in other segments of the East Kunlun fault zone. The results of this study support the 'continental escape' model. | Zhang Junlong Ren Jinwei Fu Jundong Hu Chaozhong Xiong Renwei Chen Changyun Yang Panxin | 2012 | Earthquake Research in China2012，26，4： | 0 |
| 11 | Study of Paleoearthquakes by Excavation of Grouped Trenches on the Zemuhe Fault in Daqingliangzi,Xichang,Sichuan显示文摘Uncertainties are common in the dating of paleoearthquakes.To improve the credibility of the dating of paleoearthquakes,analysis was done on fault activity,sedimentary environment and seismo-geomorphology to investigate paleoearthquakes along the Zemuhe active fault zone.Grouped trenches were excavated near Daqingliangzi,which revealed three palaeoearthquake events aged 160a,3100a and 5500a~8900a,respectively,including recurrence intervals of about 3000a.Sedimentary processes related to strike-slip fault type earthquakes were discussed,and a sedimentary model was put forward for strike-slip faults at hillsides where drumlin and reverse scarp developed. | Tian Qinjian Ren Zhikun Zhang Junlong | 2009 | Earthquake Research in China2009，23，1： | 0 |
