Calculate, Share, Explore

The OpenQuake suite of open-source software comprises the Platform, the Engine, and a great variety of (desktop) Tools for modeling, and for accessing and exploring GEM products, as well as uploading and sharing data & findings. At the end of 2014, the OpenQuake Platform will become available. This web-based risk assessment platform will offer an interactive environment for modeling, viewing, exploring, and managing earthquake risk by allowing users to access, manipulate, share and add data, models and tools for integrated assessment of earthquake risk.

Many of these can be used as stand-alone products, but by combining them in integrated workflows value is added.

Using OpenQuake

A Disaster Risk Reduction professional will benefit from OpenQuake tools to facilitate disaster preparedness and policy recommendations for improving resilience. In particular, this ‘public’ user can collaborate with local experts to use OpenQuake in the support of cost-benefit analysis of risk transfer (insurance) as well as retrofitting (“seismic upgrade”). The resulting maps results will intuitively show these users, in both relative and absolute terms, how each neighbourhood will benefit from a policy being evaluated.

A Corporate Risk Manager will be able to use OpenQuake to conduct holistic risk assessment to a common standard worldwide, and inform capital investment decisions. These users will especially benefit from understanding the effects on earthquake risk from indicators of social vulnerability, resilience, and indirect economic loss.

An Insurance Modelling Analyst will benefit from OpenQuake by conducting sensitivity testing to develop a custom view of earthquake risk. These ‘power’ users will be able to estimate loss under varying assumptions. Repeating part(s) of the calculation, while adjusting parameters or investigating the underlying event sets, will provide insight to variability/uncertainty in the results.

Open source and test-driven development

The source code behind the platform, engine and tools is openly available from a public repository Live development of the code takes place on this repository, and documentation facilitates contributions by external software developers. In test-driven development, each new feature begins with the implementation of its corresponding test code, such that test coverage reaches 100%.
