The collaborative project ‘Seismic Hazard Harmonization in Europe (SHARE)" was supported by the EU-FP7 to deliver the first-ever complete, state-of-the-art hazard model, replacing older maps (ESC-SESAME. 2003). SHARE contributes its results as a regional program to the Global Earthquake Model (GEM) program initiated by the Organization for Economic Cooperation and Development.
The SHARE hazard results describe potential shaking associated with future earthquakes in Europe and serve as input for mitigation policies such as seismic risk assessment and earthquake-resistant design, covering single- and multi-storey buildings and critical infrastructures such as bridges or dams. Through coordination at the European Union level, these hazard results will help harmonize the next generation of national seismic hazard assessments and serve as a benchmark for the revision of the European seismic building code (EuroCode8). The data assembled by SHARE on earthquakes and faults will accelerate the generation of new scientific and technical knowledge to improve seismic hazard assessment in Europe.
The ground shaking is expressed in terms of the unit gravitational acceleration g. The SHARE peak ground acceleration value across Europe range from 0g to over 0.5g. Low hazard areas (PGA≤0.25g) in red-black.
