Surface deformation associated with the 2008 Ms8.0 Wenchuan earthquake from ALOS L-band SAR interferometry
The Ms8.0 Wenchuan earthquake (in China) occurred on 12 May 2008 as a result of slip on the northeastern-striking Longmen Shan (LMS) faults beneath the ruggedmargin between the Qinghai-Tibet Plateau and Sichuan Basin. The catastrophic event caused significant surface ruptures and permanent ground displacement in a wide area. This paper concentrates on mapping surface deformation caused by the m...
متن کاملSlip model of the 2008 Mw 7.9 Wenchuan (China) earthquake derived from co-seismic GPS data
Near-field co-seismic GPS data were used to derive the slip distribution of the 12 May 2008 Wenchuan earthquake. Based on field measurements and geological observations, the earthquake is represented by ruptures on the Beichuan fault and a neighboring fault from Pengxian to Guanxian, both dipping with a decreasing angle with depth. Using a layered elastic crust model, we obtained a slip model t...
متن کاملTwo-dimensional Co-Seismic Surface Displacements Field of the Chi-Chi Earthquake Inferred from SAR Image Matching
The Mw=7.6 Chi-Chi earthquake in Taiwan occurred in 1999 over the Chelungpu fault and caused a great surface rupture and severe damage. Differential Synthetic Aperture Radar Interferometry (DInSAR) has been applied previously to study the co-seismic ground displacements. There have however been significant limitations in the studies. First, only one-dimensional displacements along the Line-of-S...

متن کاملEditorial: The Foundation of the Faculty of Information Sciences and Knowledge Studies Which Did Not Last Long
In 2010, the Faculty of Information Sciences and Knowledge Studies founded in the University of Tehran but unfortunately it was closed down after 5 years. This faculty was established as a result of an agreement between the National Library and Archives of Iran and University of Tehran. This catastrophe, i.e. the dissolution of the faculty, was due to several changes, including: the change of t...
