Each special GEM session is described below. Other GEM-related presentations will be featured here as well, as soon as the conference programme is online! There will of course be many more presentations of interest and occasions to discuss how to collaborate even better together and we therefore look forward to meeting many of you in Lisbon!

SS25: Global Earthquake Model: Objectives and Activities
This Special Session will present the mission and vision of the Global Earthquake Model. The session focuses on our collaborative efforts to produce a holistic global earthquake risk model that integrates metrics of social vulnerability and resilience with the on-going activities of hazard and physical risk. The OpenQuake platform through which the integrated risk model and the tools to build it will be rendered available, will be showcased during the session. Special attention will be given to the decision support tools of the platform.
Expect the following:
- GEM: the mission and vision (Anselm Smolka): a description of the modus operandi of GEM, the status of activities, the efforts to extend beyond seismic hazard and physical risk, the OpenQuake platform and mechanisms for collaboration.
- Regional Programmes (Jochen Zschau): an overview of the activities through which the critical cumulated knowledge, experience and feedback of scientists from all regions is brought into the model building exercise.
- Social Vulnerability and Disaster Resilience in GEM (Christopher Burton): a summary of the activities to build upon existing efforts for the development of an integrated risk assessment approach within GEM
- Mainstreaming of Hazard, Vulnerability and Risk Parameters in Core Functions of Local Governments (Fouad Bendimerad): a discussion of how risk outputs can be integrated and transformed into City Risk Profiles and Atlases; Disaster Management Planning, Risk Sensitive Land Use Planning; Disaster Risk Reduction policy, etc. based on the Earthquakes and Megacities Initiative (EMI) disaster risk management master plan model.
- Decision-support tools (Helen Crowley): a tour of the envisaged decision support capabilities of the OpenQuake platform, such as the retrofitting and insurance cost-benefit calculators
- Testing and Evaluation (Danijel Schorlemmer): the efforts to 'test' or validate the models within GEM, to verify whether the models indeed describe a real system within the limits of its uncertainties
Panellists: Mary Comerio and Haruo Hayashi
Conveners: Rui Pinho and Anselm Smolka
SS26: Global Earthquake Model’s hazard activities
This Special Session will contain presentations on GEM’s hazard activities, which include a vast spectrum of methods, software, tools and databases required for the calculation of seismic hazard. The aim of the session will be to discuss the results obtained by different GEM groups (e.g. Global Components projects, Regional Programmes, GEM Model Facility) and solicit feedback from the engineering and scientific communities.
This session is an opportunity to continue GEM's dissemination and community engagement processes (see for example GEM's community platform Nexus.
Expect the following:
The GEM Hazard Global Components, catalogues, faults and geodetic strain (Ross Stein): a review of GEM’s hazard global components on neotectonic faults, instrumental and historical earthquakes and a global geodetic strain rate model.
Global Ground Motion Prediction Equations (Yousef Borzognia): the efforts of a distinguished international team of experts to use a unified, transparent and collaborative approach to select a harmonized suite of ground motion prediction equations (GMPE) that can be used at global and regional scale.
Tectonic Regionalisation (Marco Pagani): a summary of the work on the creation of regionalisation scheme/methodology able to provide for each point on the globe a corresponding set of GMPEs and magnitude scaling relationships.
OpenQuake Modeller (Graeme Weatherill): a presentation of the tool for developing PSHA input models.
Regional hazard model development for Europe (Domenico Giardini): the outputs of the European Regional Programme SHARE.
Challenges in regional hazard model development for Sub-Saharan Africa (Atalay Ayele)
OpenQuake Engine [Hazard] (Damiano Monelli): a tour of the hazard calculation capabilities of the open-source OpenQuake Calculator software, being developed in the context of GEM.
Panellists: Gail Atkinson, Emile Okal
Conveners: Marco Pagani. Paolo Bazzurro
SS27: Global Earthquake Model’s physical risk activities
This Special Session discusses GEM’s physical exposure and vulnerability activities which include methods, software, tools and databases required for the calculation of seismic risk. The aim of the session is to solicit feedback from regional and local experts and encourage them to test and improve the preliminary products of GEM, and get involved in the collaborative development through GEM Nexus.
Expect the following:
GEM Building Taxonomy (Charles Scawthorn and Svetlana Brzev): a scheme for classifying buildings from all over world.
Global Earthquake Consequences Database (Emily So and Antonios Pomonis): the collection of post-earthquake data such as loss of life, injuries, damage and economic loss into a common web-based repository.
Global Exposure Database (Kishor Jaiswal): a global building and population inventory.
Inventory Data Capture Tools (John Bevington): innovative open-source tools to support the population of the exposure and consequences databases
Extending EMS-98 for Global Application (Robin Spence): proposed modifications to the current version of the European Macroseismic Scale to make it more specifically applicable to areas outside Europe with significantly different building stocks.
OpenQuake Engine [Risk] (Vitor Silva): a tour of the risk calculation capabilities of the open-source OpenQuake software, being developed in the context of GEM.
Panellists: Bob Reitherman, Gian Michele Calvi, Stefano Pampanin
Conveners: Helen Crowley, Robin Spence
