Seismic hazard, also referred to as earthquake hazard, is composed of different input data, representing the main components of the current seismic hazard model of Switzerland.
The assessment is based on knowledge of past earthquakes, geology and tectonics, and requires a reference rock model to be determined as a basis for the seismic hazard model. The datasets underlying these factors are combined into a seismic hazard model that can be used to estimate where earthquakes of different magnitudes may occur, how frequently they are expected to happen, and how probable certain levels of ground shaking due to earthquakes are. Recent scientific knowledge and research results are also required in order to reliably assess and estimate the different ground shaking levels in Switzerland.
