OpenQuake Platform

An integrated platform for risk assessment

A web-based GIS platform that allows a user to visualise, explore and manipulate GEM’s datasets, models and results; to access the engine for running computationally intensive hazard and risk calculations; to access and download offline tools and to contribute, share and discuss their data, new findings and results with the GEM community; V1 planned for end 2014.

Most of GEM's products can be found in the platform, for online use or for download and offline use. These are mostly resources in their own right, but their value increases by being able to combine them inside the platform. Some of the products are to be combined in an integrated workflow to perform a certain task, such as developing an exposure model, or developing a dataset on earthquake consequences.

A demo-version of the platform is being developed. V1.0 will be released at the end of 2014. 

Below a current overview of the products and services that GEM plans to render available; the overview is subject to change over time.


Global uniform earthquake-related datasets

Software Tools

The code of our software is mostly open and available from our repository on the Github website. Many of them are not yet ‘packaged’ so that they can be used / installed separately, or do not feature a user interface.

  • OpenQuake Engine: state-of-practice software for hazard, physical risk and integrated risk calculations - available for online use through OATS; local installation possible as well through a virtual image.
  • OpenQuake Fault Capture Tool: tool to capture new data on active faults around the globe – available in the OpenQuake Platform (2014)
  • OpenQuake Modeller: a suite of mainly offline tools that help experts to develop input models for the OpenQuake Engine, either for hazard and for (physical) risk calculations / modeling:
    • Hazard; Earthquake catalogue homogenization tool - prototype code available from Github
    • Hazard; Modelling Tools – available for collaborators July 2013, later for others
    • Risk; Exposure Modelling Tools available for collaborators July 2013, later for others
    • Risk; Physical Vulnerability Modelling Toolsavailable for collaborators December 2013, later for others
  • OpenQuake Inventory Capture Toolkit: a suite of tools to support GEM stakeholders in extracting datasets, models and information on buildings from field observations as well as remote sensing, both pre- and post- earthquake disaster
    • OpenQuake Inventory Direct Observation Tool Windows - prototype code available from Github
    • OpenQuake Inventory Direct Observation Tool Android - prototype code available from Github
    • OpenQuake Inventory Spatial Damage Data App (SIDD) - prototype code available from Github
    • OpenQuake Inventory Building Reconnaissance App (BREC) – available from June 2013
  • OpenQuake Toolkit for Socio-Economic Indicators and Integrated Earthquake Risk
    • Tools that help stakeholders with knowledge of the local context to compose indicators for socio-economic vulnerability and disaster resilience – available in the OpenQuake Platform (2014)
    • Tools that allow users to calculate and combine earthquake hazard and physical risk with composite indicator on socio-economic vulnerability, to understand the drivers of risk in an area -  available in the OpenQuake Platform (2014)


Input models required for seismic hazard and physical risk calculations

Together with collaborators worldwide we are developing both global ‘uniform’ models, as well as regional models and we are working to feature as many national and regional models in our platform as possible - available in the OpenQuake Platform (2014)

  • Regional/national PSHA models - we are aiming to provide different models for as many regions in the world as possible. These can cover an entire region, a nation or even smaller areas. Most of these models will be community developed and GEM rated1, others will be based on existing models. The regions we plan to cover by 2014 are as follows; after 2014 through the platform and further collaboration we envisage many more models to become available:

    • Caribbean
    • Central America
    • Central Asia
    • Europe
    • Middle East
    • North America
    • North-East Asia
    • Oceania & South-East Asia
    • South America
    • South Asia
    • Sub-Saharan Africa

1 = Based on a set of criteria that will be discussed and agreed upon within GEM’s scientific community

  • Global 'uniform' models - models that are based on the GEM global homogenised datasets and hence follow as much as possible a uniform strategy. These models can be used for benchmarking of outcomes with regional models, for rough comparisons between countries (for example of estimated losses or socio-economic resilience) and as a basis for learning and joint improvement. They will likely feature much uncertainty and therefore through the platform we will provide access both to a global hazard (PSHA) model and a global risk model, as well as to a set of regional/national models, that we will rate and review. The global models hence incorporate the knowledge and data currently publicly available, and best practice put together by international experts, using GEM tools and will improve over time with contributions from stakeholders worldwide, as they work with the models and as new data and science can be incorporated. By mid 2014 we will collate first versions of the global ‘uniform’ models.

    • Global ‘Uniform’ Hazard (PSHA) Model
    • Global ‘Uniform’ Risk Model

Best practice, methods, guidelines

  • GEM Building Taxonomy; a comprehensive global classification scheme for buildings, for capturing all different building types that exist around the globe with a common language technical reports – available already through GEM Nexus


These results will be produced from running the models outlined above the OpenQuake Engine. In v1.0 the results will be applicable mainly for the global / national level and stakeholders will be able to develop more detailed results at local levels and share these with all other users - available in the OpenQuake Platform (2014)

  • Global ‘uniform’ hazard maps and regional hazard maps
  • Global ‘uniform’ hazard curves
  • Stochastic event sets
  • Ground motion fields
  • Uniform hazard spectra
