1. GEM: the mission and vision
Anselm Smolka, Chairman Governing Board, GEM Foundation

2. What is GEM?
“A collaborative effort devised and launched by OECD’s Global
Science Forum, aimed at engaging the global community in the
transparent design, development and deployment of uniform
open standards and tools for earthquake risk assessment
worldwide”

3. Why GEM?

4. Why GEM?

5. The rationale I
Global
Seismic
Risk:
Earthquake
disasters
since 2004

6. The rationale II
‣ advanced seismic hazard and risk assessment tools and resources
out of reach for many potential users
‣ similar issues, different approaches
≠

7. Public-private partnership
‣ Combining the strengths, knowledge and needs of both sectors
‣ Growing: currently 10 companies, 15 public organizations
representing nations or regions, 8 international organizations

8. Looking at risk holistically

9. Collaborative Development
TESTING & EVALUATION FACILITY
‣ Data
‣ Tools
‣ Best Practice

10. Global Projects: Hazard
Global Earthquake History
Global Instrumental Earthquake Catalogue
Global Active Fault and Seismic Source Database
Global Ground-Motion Prediction Equations
Global Geodetic Strain Rate Model

11. Global Projects: Exposure and physical vulnerability
GEM Ontology and Taxonomy
Global Exposure Database
Global Earthquake Consequences Database
Global Vulnerability Estimation Methods
Inventory Data Capture Tools

12. Global Projects: Social Vulnerability and Resilience
Goal
Facilitate the implementation of
indicators, indices, and assessment
standards for capturing the social
vulnerability, disaster
resilience, and indirect (economic)
loss vulnerability of societies to
earthquake impacts.
Project
Development of indices and tools for integrated risk assessment

13. Regional Collaboration
By creating regional programmes
and networks scientists in the
different countries can provide
feedback on global standards and
bring in local data and knowledge. SHARE, NERA, Syner-G EMME EMCA
Regional workshops

14. Worldwide collaboration
Since starting in 2009 GEM has become a truly global effort

15. Tools, software, GIS-platform
Open-source development of software and IT-infrastructure

16. GEM in a nutshell
‣ State-of the-art
‣ Transparent and open
‣ Independent
‣ Commmunity owned
‣ Global
‣ Standardized, but flexible
‣ Rigorous testing & validating
‣ Accessible
‣ Serving multiple users

17. Dynamic Risk Assessment Platform
‣ model, analyse, explo
re, share
‣ different ‘suites’
tailored to our
stakeholders
‣ first version 2014
‣ transparency
‣ common data
exchange format
‣ models, tools, data

18. Using the platform
Develop custom output and risk information
Custom hazard, loss and risk maps
Create event-loss tables, get insight into average annual loss and occurrence
exceedence probability, obtain spatial distributions of cost-benefit ratio’s
Use GEM risk information
Access and use GEM maps, graphs, indices and other info
Overlay maps to have a better understanding of risk components
Access documentation to get insight into the methodologies and
approaches

19. Results and outputs
OpenQuake Engine tested
and used in more than 45
countries
Already used for national
hazard maps, regional
programmes, scientific
projects

20. Results and outputs
Global projects are delivering more and
more output as they are progressing.
Some examples:
- The ISC-GEM global instrumental
catalogue
- A taxonomy of buildings
worldwide, plus an online glossary
- A report on pre-selection of ground
motion prediction equations
[GMPEs] for the globe
- A report on guidelines for data
collection for earthquake
consequence data
See www.nexus.globalquakemodel.org

21. Vision
‣ Working together to assess risk: worldwide use of the
OpenQuake Platform and other resources
‣ Extending and enhancing tools and methods
‣ Technology transfer and knowledge exchange
‣ Intensified regional collaboration
‣ New global projects: other and secondary perils, time
dependence/aftershocks, infrastructure
=> Staying there, alive and dynamic

22. Roadmap

23. Get involved
