Helen Crowley 23rd July 2014 – 10th U.S. Na4onal Conference on Earthquake Engineering
@GEMwrld #10NCEE
OpenQuake Components and Status
• OpenQuake pla7orm
– Web-‐based access to engine, data, models, results and tools
– Work in progress, v1.0 release end 2014
• OpenQuake engine
– Calculate seismic hazard and physical risk
– v1.0 released in June 2013
– Development con4nues
• OpenQuake desktop tools
– Prepare input models for OpenQuake engine
– Social Vulnerability and Integrated Risk models
– Work in progress, v1.0 release end 2014

Session W35, Wednesday 5:30 – 6:45pm
OpenQuake Component Interac4on
OpenQuake Community Interac4on
• A mul4-‐purpose tool – Hazard and physical risk calcula4ons
• Open and Transparent – Take a look at the code on h^p://github.com/gem
• Modular – The engine is organised into a number of scien4fic libraries (OQ-‐hazardlib, OQ-‐
risklib, OQ-‐nrmllib) • Runs on clusters and laptops
– Op4mised for large-‐scale calcula4ons on Linux clusters, but also runs on a laptop
• Documented – We produce documenta4on on the methods behind the code and how to use
the engine, and publish in peer-‐review journal publica4ons • Tested
– Tes4ng is an integral part of the development process
OpenQuake Engine Features
• Calculators:
– Classical Probabilis4c Seismic Hazard (PSHA) and Risk Analysis (PSRA)
– Event-‐based PSHA and PSRA – Scenario hazard, damage and loss assessment
– Disaggrega4on of hazard, damage and losses
– Retrofigng cost-‐benefit analysis
• Tested
– Tes4ng is an integral part of the development
– process

5. Demonstrative examples
(a)
Figure 5.3. – Hazard curves as obtained from the LogicTreeCase2 demo. Solid gray linesrepresent individual hazard curves from the different logic tree path (a totalof 324 curves). The red dashed line represents the mean hazard curve, whilethe red dotted lines depict the quantile levels (0.15, 0.5, 0.95).
LogicTreeCas3ClassicalPSHA illustrates an example of logic tree defining rela-tive uncertainties on G-R maximum magnitude and b value. A single sourcemodel is considered containing two sources belonging to different tectonic re-gion types and both characterized by a G-R magnitude frequency distribution.The source model logic tree is as follows:
<?xml version="1.0" encoding="UTF-8"?><nrml xmlns:gml="http://www.opengis.net/gml"
xmlns="http://openquake.org/xmlns/nrml/0.4"><logicTree logicTreeID="lt1">
<logicTreeBranchingLevel branchingLevelID="bl1"><logicTreeBranchSet uncertaintyType="sourceModel"
branchSetID="bs1"><logicTreeBranch branchID="b11">
<uncertaintyModel>source_model.xml
</uncertaintyModel><uncertaintyWeight>1.0</uncertaintyWeight>

• Sign up for the OpenQuake Alpha Tes4ng Service (OATS) on GEM website
• Install a Virtual box image (of Ubuntu and the OpenQuake-‐engine) on your laptop
• Install the engine on a Linux cluster (with the help of GEM’s developers)
• Run calcula4ons through the OpenQuake pla7orm (from 2015)..
