1. OPENQUAKE Mission and Vision It is GEM’s mission to engage a global community in the design, development and deployment of state-of-the-art models and tools for earthquake risk assessment worldwide. OECD’s Global Science Forum created the opportunity for an initiative to leverage (scientific) knowledge on earthquake risk for the benefit of society, worldwide. What GEM envisions and has started to work on, is the bringing together of state-of-the-art science and national, regional, international organisations as well as individuals, in a global collaborative effort that will have a lasting impact on seismic risk assessment.

2. OPENQUAKE OpenQuake is an open source software application that allows users to compute seismic hazard and risk on any scale. What is ?

3. OPENQUAKE OpenQuake can be downloaded from www.openquake.org where the latest version is available with the installation documentation.www.openquake.org How to get ?

4. OPENQUAKE The OpenQuake team coodinates through many communication channels such as IRC, mailing lists, blogs, forum, etc… How do I get support from ?

5. OPENQUAKE What calculators does have today ?

6. OPENQUAKE Classical PSHA-based risk calculator Hazard Model Classical PSHA hazard curves calculator Classical PSHA-based risk calculator Loss curves Hazard curves Vulnerability functions Exposure model

7. OPENQUAKE Probabilistic event-based calculator Vulnerability functions Exposure model Hazard Model Earthquake rupture forecast calculator Stochastic event set calculator Ground motion field calculator Prob event-based risk calculator Prob event-based risk calculator Loss curves

8. OPENQUAKE Architecture

9. OPENQUAKE What can I calculate with today ?

10. OPENQUAKE Currently OpenQuake is alpha-code meaning that it is a development release and all interaction with the tool is through a terminal interface

11. OPENQUAKE Hazard Curves Curves that give the probability of exceedance of a certain intensity measure level, within a time span.

12. OPENQUAKE Hazard Maps Distribution of the expected ground motion for a certain probability of exceedance with a given time span

13. OPENQUAKE Loss curves Curves that give the probability of exceedance a certain loss, within a time span. No Image at this time

14. OPENQUAKE Loss maps Distribution of the expected losses for a certain probability of exceedance with a given time span

15. OPENQUAKE Where can I find documentation about what calculates?

16. OPENQUAKE All the calculations, equations and assumptions inside of the OpenQuake engine are described in detail on the OpenQuake book. OpenQuake book

17. OPENQUAKE What will I calculate with In the future?

18. OPENQUAKE Future releases of OpenQuake will include a Web based user interface

19. OPENQUAKE Seismic Hazard disaggregation The disaggregation provides the contributions to the hazard of discrete combinations of basic parameters considered in the calculations (e.g. magnitude, rupture-site distance)

20. OPENQUAKE Ground motion fields for single events Distribution of the ground motion in a region for a single earthquake

21. OPENQUAKE Disaggregation of losses The disaggregation provides the contributions to the losses of discrete combinations of basic parameters considered in the calculations (e.g. magnitude, rupture-site distance)

22. OPENQUAKE Plus… Uniform hazard spectrum calculator; Analytical methods to estimate vulnerability; Assessment of critical facilities and lifelines; Socio-economic impact; All additional contributions from the OpenQuake community!
