To understand the seismic faulting mechanism and surface deformation features associated with the Wenchuan earthquake, including rupture length, geometric characteristics, and slip distribution of co-seismic surface rupture, our survey group traveled to the epicentral area 2 days after the earthquake and undertook 10 days of fieldwork, during which time we collected fundamental data related to rupture structures and the spatial distribution of offset along faults. Based on the results of this preliminary ?eldwork, we carried out additional detailed ?eldwork along the co-seismic surface rupture over the following year. This photographic atlas shows the main deformation characteristics of co-seismic surface rupture and the nature of the earthquake disaster and subsequent relief operations, based on photographs taken during our ?eld investigations. This atlas is intended not only for geologists, seismologists, and engineers as a means of furthering their understanding of the seismic mechanisms and surface rupture deformation characteristics of large intracontinental earthquakes, but also for advanced undergraduates and graduate students as a textbook. We are grateful to the many organizations and individuals who helped to make this book possible. Thanks are also due to Professor Dong Jia and Dr. Xiaojun Wu of the Nanjing University for their assistance in the ?eld.
