Abstract (321) HTML (179) PDF (2183KB)(43)
Abstract:
At 7:49:40.7 on April 14, 2010, a MS 7.1 earthquake happened in Yushu County of Qinghai Province. In the field investigation two surface rupture zones were observed from west to east, Longbaotan surface rupture zone and Yushu surface rupture zone. They display NW trending and are respectively develo...
D-INSAR OBSERVATION OF EARTH SURFACE DEFORMATION IN THE MS7.1 YUSHU EARTHQUAKE
YAO Xin, ZHANG Yong-shuang, YANG Nong, XIONG Tan-yu
2010, 16(2): 129-136.
Abstract (185) HTML (137) PDF (994KB)(17)
Abstract:
A "Two Paths+DEM" interferometric process was made for the PALSAR SAR data before (Jan. 15, 2010) and after (Apr. 17, 2010) the Yushu MS7.1 Earthquake, which yielded a high-quality co-seismic InSAR strip image and absolutely surface deformation. Based on the deformation scale, deformation magnitude ...
NUMERICAL MODELING FOR MECHANISM OF YUSHU MS7.1 EARTHQUAKE
WANG Lian-jie, CUI Jun-wen, WANG Wei, QIAO Zi-jiang, SUN Dong-sheng, ZHAO Wei-Hua
2010, 16(2): 137-145.
Abstract (198) HTML (103) PDF (671KB)(11)
Abstract:
In this paper, strain softening model is used to establish the modeling for Yushu MS7.1 earthquake. The results shows that Yushu MS7.1 earthquake occurred as a combination of northward compressing of the Indian Plate and southeastward compressing of the Qinghai-Tibet Plateau. The stress drop, energy...
FORMATION MECHANISM OF GEO-HAZARDS TRIGGERED BY WENCHUA MS8.0 EARTHQUAKE ALONG DUJIANGYAN-WENCHUAN HIGHWAY
GAN Jian-jun, HUANG Run-qiu, LI Qian-yin, YE Xiao-hua, GAO Wen-jun
2010, 16(2): 146-158.
Abstract (238) HTML (174) PDF (1310KB)(9)
Abstract:
The geological hazards induced by the Wenchuan MS8.0 earthquake along the Dujiangyan-Wenchuan Highway are especially severe and have seriously affected the safe riding along the highway and the reconstructions. In order to prevent and reduce disasters effectively, main geo-hazard type, slope failure...
ESTIMATION OF MAJOR EARTHQUAKE CYCLE AND FUTURE TENDENCY IN HEXI CORRIDOR AND ITS ADJACENT AREA, NW CHINACHEN
CHEN Bai-lin, LIU Jian-sheng, ZHANG Yong-shuang, LIU Jian-min, DONG Cheng, WU Nai-fen
2010, 16(2): 159-175.
Abstract (320) HTML (95) PDF (951KB)(15)
Abstract:
The Hexi corridor, with its particular geographical position, is an important line connecting middle and lower reaches of the Yellow River and NW China. Affected by the late Mesozoic-early Cenozoic collision between Indian Plate and Eurasian Plate and the continuous northward compression the Hexi co...
A REVIEW ON STUDY OF ACTIVITY OF XIANSHUIHE FAULT ZONE SINCE THE HOLOCENE
XIONG Tan-yu, YAO Xin, ZHANG Yong-shuang
2010, 16(2): 176-188.
Abstract (543) HTML (209) PDF (1261KB)(74)
Abstract:
The Xianshuihe fault zone is a large active seismic-genetic zone in mountainous regions of southwest China. Based on previous studies, in combination with field investigation, the authors systemically summarized the research status about Holocene activity of Xianshuihe fault zone. The fault zone is ...

2010, 16(2): 189-202.
Abstract (197) HTML (114) PDF (1709KB)(9)
Abstract:
The Sayak ore field is the only area with the occurrence of large-scale skarn-type copper deposit in Balkhash metallogenic belt, Kazakhstan, Central Asia. In this paper the geological characteristics, ore-field structures and metallogenic model of Sayak ore field are described in detail. Sayak ore f...
