... Abstract In this paper we use three-dimensional spherical shell finite element model of power-law creep mechanism, to analyze the stress field variation in china mainland caused by the brittle failure of Longmenshan fault, during 5.12 Wenchuan earthquake. We establish a local coordinate system...

... district. 1 INSTRUCTIONS The Sep 21, 1999 Chi-Chi, Taiwan, earthquake (Mw7.6) is the largest inland earthquake that occurred in Taiwan in the 20th century, while the May 12, 2008 Wenchuan earthquake (Ms8.0) is the most affected earthquake to China in the beginning of the 21st century. In this study, we...

... ABSTRACT: The 2008 Wenchuan earthquake, Mw 7.9, ruptured the Longmenshan fault zone at the eastern margin of Tibetan Plateau and formed a 240-km-long surface rupture zone along the Yingxiu-Beichuan fault and an additional 70-km-long surface rupture zone along the Guanxian-Jiangyou fault. Some...

... ABSTRACT: The Wenchuan earthquake(Ms=8.0) suddenly happened on May 12th 2008 in Sichuan Province,China. This earthquake produced a 240 km-long co-seismic surface rupture along the Longmenshan Central Fault. We mainly focus on three regions along the co-seismic surface rupture: the Nanba Town...

... ABSTRACT: We collected all of the well-water level data and bore-hole volume strain data with step-like changes induced by the 2008 Wenchuan Earthquake, and then compared the two kinds of data simultaneously obtained from one-well and obtained from two monitoring network, based on earth tide...

... ABSTRACT: One week before the occurrence of Wenchuan Ms8.0 Earthquake the maximum horizontal principal stress measured by hydro-fracturing technique in the seismogenic fault zone of Wenchuan Earthquake (Yingxiu-Beichuan fault) at 400±m depth was 21∼22MPa, which was 8∼10MPa higher than...

... ABSTRACT: This paper summarizes the typical features and their regularities of the observed coseismic surface ruptures by Wenchuan Earthquake in terms of the three faults, ground locations, ground geomaterials, rupture geometries and rupture displacements. The paper then uses both...

... ABSTRACT: The sudden and unexpected Wenchuan earthquake occurred on the Longmen Shan Fault. The dynamic mechanisms of the event remain enigmatic although much work has been done by scientists. In order to know more about the behaviors of the Longmen Shan thrust fault, we simulate...
