Global Components

Ten Global Component projects are currently being carried out by groups of international experts and organisations, in order to develop global uniform databases, tools and standardized methods as input to the model:

HAZARD

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.

EXPOSURE/VULNERABILITY

GEMECD; Global Earthquake Consequences Database
	The aim of this project is to create a structure to assemble and to store earthquake consequence data in a web-accessible way. Data to include comprise building damage, damage to lifelines and other infrastructure, ground failure, human casualties, social disruption, financial and economic loss. The consortium is led by CAR Ltd and comprises furthermore CRED, ERN-AL, GNS, KOERI, Kyoto University, Munich Re, SPA Risk and USGS.
GED4GEM; Global Exposure Database
	The GED4GEM project aims to create the first open database of global building stock and population distribution containing the spatial, structural, and occupancy-related information needed for damage, loss and human casualty (estimation) models to be deployed in GEM. The project is carried out by the University of Pavia, CIESIN, IES-CEA, IGP-CEA, ImageCat, JRC, UN-HABITAT and USGS.
IDCT; Inventory Data Capture Tools
	This project has 2 main goals: a) provide tools to enable capture and transfer of high-resolution inventory or damage data into either the GED and GECD, and b) develop tools to merge data collected using Remote Sensing with data acquired from Direct Observation. ImageCat leads the consortium. Other partners are BGS, CAR, CEDIM, DLR, Nottingham University, OpenGeo, Pavia University, SPA Risk, Stanford Univeristy and WAPMERR.
Global Vulnerability Estimation Methods
	The aim of this project is to provide standards for vulnerability estimation (i.e. the estimation of building damage, both structural and non-structural, and associated social and economic loss) using a number of different methods (empirical, analytical, expert opinion) and a range of measures of ground-motion intensity. The consortium, consists of the University of Colorado, University of Chile, Geoscience Australia, EERI, Stanford University, UCL, University of Bath, USGS and Willis.

RISK AND IMPACT ANALYSIS

GEM Ontology and Taxonomy

This project foresees the development of a technical communications and coordination programme, definition of a set of concepts used in GEM and the relationship between them (a GEM ontology). Furthermore an initial GEM taxonomy is to be developed that can be sustained in the future (i.e. a classification of things in an ordered system that reflects their relation). AGORA, DPRI, PEER and WHE-EERI are the institutions that carry out this 3-year project.
