Hazard Global Components

Five global components are currently being developed by the international community as input to the Global Earthquake Model, within the scope of the Hazard Module.

Global Instrumental Earthquake Catalogue
	After collection and critical review of existing global instrumental catalogues, the project consortium is developing a methodological approach for a new catalogue and will subsequently compile it. The consortium consists of six international experts, backed up by their teams, and is led by the International Seismological Centre (ISC, UK) in collaboration with IASPEI.
Global Active Faults and Seismic Source Database
	The main task of the Faulted Earth project is the compilation of a global database of active faults, covering more areas than before. An interactive tool for updating the database is also part of the project. GNS is leading the effort, in collaboration with the Earth Observatory of Singapore, and the Universidad Nacional de San Luis. Local researchers are involved extensively.
Global Ground Motion Prediction Equations
	The main goal of this project is the development of a harmonized suite of ground motion prediction equations (GMPEs) that can be used at both the global and regional level for hazard and risk assessment, built on the most recent advancements in the field. The Pacific Earthquake Engineering Research Center (PEER) leads the project that furthermore features active participation of 27 international experts.
Global Earthquake History
	This is project devoted to developing tools for compiling a Global Earthquake History, starting with existing regional initiatives and anticipating new regional capacities yet to be developed. Earthquakes with M≥7.0 at minimum, in the time window 1000-1903 are mainly considered. The 2-year project is coordinated by two leading institutions: INGV and BGS. Regional expertise is sought through ad-hoc contracts with institutions or individuals.
Global Geodetic Strain Rate Model
	Earthquakes release accumulated crustal strain, and therefore strain rate is a proxy for earthquake potential. The creation of a comprehensive and uniform model for geodetic strain rates is pursued by the consortium, which will significantly update the Global Strain Rate Model of 2004. Tasks are overseen by PI's from University of Nevada, Ecole Normale Supérieure, University of California/CEA and UNAVCO.
