    It is often assumed that the majority of the interseismic strain accumulates around the major mapped geological block boundaries. However, numerous recent earthquakes in the continents have occurred on faults that were previously unidentified. Existing deformation data from Tibet are insufficiently dense to map the distribution of interseismic strain. Here we combine 265 interferograms formed from 166 radar images with GPS data to constrain a high-resolution velocity field covering ∌200,000 km 2 of western Tibet. We confirm that the slip rate of the Karakoram Fault is low (<6 mm/yr), but show that areas of focused strain do not coincide with the major fault structures. Some of this strain is due to postseismic relaxation after a M w 6.8 earthquake that occurred in 1996 on a structure that is difficult to identify in satellite imagery. Models of seismic hazard that rely on imperfect knowledge of the boundaries of crustal blocks can therefore underestimate hazard from unknown faults. Copyright 2012 by the American Geophysical Union

    Objective This study investigated the effect of the Jennings Disaster Nursing Management Model-based and learning management system-assisted six-module training programme on nursing students' disaster preparedness perceptions and response self-efficacy. Design and sample This randomized controlled trial used a two group comparison design, experimental group (n = 127), and control group (n = 108), carried out with third-year nursing students in a city in the west of Turkey. Measures Data included a socio-demographic form, the Disaster Preparedness Perception Scale in Nurses (DPPSN) and the Disaster Response Self-Efficacy Scale (DRSES). Results After the training, disaster preparedness perceptions and the response self-efficacy of the EG increased significantly (p < .05). This study had a moderate effect on participants' knowledge and self-efficacy. Conclusion Public health nurses are health professionals with important roles and responsibilities in the stages of disaster preparedness, response, and recovery that is all stages of disaster management. This theoretical-based program can be considered for both students and nursing professionals
