GEM's 2018 global hazard and risk models
Pagani, M., Silva, V. et.al
This special issue of Earthquake Spectra documents the supporting research critical to the development of the Global Seismic Hazard and Risk models by the GEM (Global Earthquake Model) Foundation, representing a major step in understanding earthquake risk globally. Seismic hazard and risk models are needed for accurate assessment of risks in order to promote risk reduction and mitigating actions, such as the improvement of building codes and construction practices, sustainable land use, emergency response, and protection of critical infrastructures, as well as risk transfer through insurance.
GEM’s Global Seismic Hazard Model comprises a mosaic of 30 probabilistic seismic hazard models. Using this collection of hazard models as input, GEM computed a Global Seismic Risk Model depicting the average Annual Economic Losses (AEL) caused by ground shaking on the residential, commercial, and industrial building stock. Additional results were successively compiled including global maps for different intensity measure types, soil conditions and return periods. This collection of papers is intended for scientists and researchers in the hazard and risk modeling sector, and risk professionals for application to disaster risk reduction around the globe.
This issue is made possible with partial support by the Global Earthquake Model (GEM) Foundation. Founded in Pavia, Italy in 2009, GEM is a non-profit public-private partnership that drives global collaborative efforts to develop scientific and high-quality resources for transparent assessment of earthquake risk and to facilitate their application for risk management around the globe.
