Abstract COGEAR is an interdisciplinary natural hazard project for investigating the hazard chain induced by earthquakes. It addresses tectonic processes and the related variability of seismicity in space and time, earthquake forecasting and short-term precursors, and strong ground motion as a result of source and complex path effects. We will study non-linear wave propagation phenomena, liquefaction and the triggering of landslides in soils and rocks as well as the potential of earthquake-induced snow avalanches. Our focus will be on the physics of non-linear processes in relation to topography, geological disposition and slope stability. The Valais, and parts of the Rhone, Visper and Matter valleys specifically have been selected as study areas. The tasks include detailed field investigations, development and application of numerical modeling techniques, assessment of the susceptibility to seismically induced effects and installation of different monitoring systems to test and validate our models. These systems are for long-term operation and include a continuous GPS and seismic network, a test installation for observing earthquake precursors, and a system to study site-effects and non-linear phenomena in two test areas (Visp, St. Niklaus-Randa). This project will prepare a follow-up risk-related study of impacts on buildings, infrastructure, and society. As a multidisciplinary national program, the scientific and organizational structure underlying this effort combines various disciplines to strengthen and extend partnerships.
