Use, share and enhance GEM's tools and resources

Below is an overview of all GEM products that are being released with the OpenQuake Platform or are under development. Products are divided into the following categories:

​

- OpenQuake Platform
- Software/Tools 
- Data
- Models
- Best Practice & risk assessment approaches
- Risk Information

OpenQuake Platform

An integrated platform for risk assessment

The OpenQuake Platform is a web-based application that allows the community to explore datasets and models and to use tools to:

​

  • visualize, explore and manipulate GEM’s datasets, tools and risk information;

  • access and download offline tools and other resources; and

  • contribute, share and discuss data, new findings and results with the GEM community.

Software/Tools

OpenQuake engine - GEM’s state-of-practice software for earthquake hazard and risk modeling.

​

  •  The latest version can be installed on laptops, workstations or servers. Windows, macOS and Linux systems are supported as well as cloud and HPC deployment.

  • Several papers have been published about the engine

  • The hazard part of the engine has been externally reviewed

  • The code of the software is open and available from repositories on Github.

 

The engine is being used by a great variety of companies, national and local institutions responsible for risk assessment, as well as individual scientists and professionals. In september 2015, an external panel of experts reviewed the hazard component of the engine.

​

Integrated Risk Modelling Toolkit

A comprehensive toolkit that works as a plugin to the QGIS software, with two main functions: 1. to develop indicators of social and economic vulnerability or resilience, and 2. to combine measures of physical risk with the above indicators to obtain integrated risk estimates.

​

  • Look for SVIR in the QGIS plugin directory, download and install the latest version

  • Upload completed integrated risk models to the OpenQuake Platform to share with the community

  • The OpenQuake Platform features a viewer for Social Vulnerability Indicators.


Model Development and Post-Processing Tools

Tools developed by GEM scientists (Secretariat and partners) to support model development.

​

​

  • Ground Motion Toolkit: A suite of tools for exploring the empirical ground motion prediction equations implemented in the OpenQuake engine and for assisting the hazard modeller in their selection

​

  • Risk Modeller’s Toolkit (rmtk): tools for engineers to create fragility and vulnerability input models needed to run risk calculations with the OpenQuake engine.

 

Data Capture Tools

​

  • Inventory Data Capture Tools: a set of tools and accompanying user protocols to enable users to collect building information pre and post earthquake and turn them into datasets.

​

 

Knowledge Sharing & Data Facilitating Apps

TaxTweb: Tool to facilitate use of the GEM Building Taxonomy

​

​
 

Supporting Tools

There are various tools that can help you in using the OpenQuake engine and other GEM products. These are prototypes or are of experimental nature, and can be found on Github’s Science Tools Repository. 

Data

Experts from around the globe have worked on developing global uniform datasets that can reliably support the creation of hazard and risk models. They can be explored through the OpenQuake Platform and combined to obtain new insights into hazard and risk. Some datasets can be downloaded in their entirety.
 

Models

Input models for seismic hazard and physical risk calculations

A repository of earthquake hazard, physical risk and integrated risk models at regional, national, sub-national and local levels. These models are either OpenQuake implementations of existing models, generated through external collaborators, or are models created through projects that are directly managed by the GEM Foundation.

​

 

  • The following GEM models are under development or scheduled:

    • A hazard, physical risk and integrated risk model for South America, and detailed models for Quito, Lima and some other cities, collaboratively developed as part of the SARA project 

    • A hazard, physical risk and integrated risk model for Eastern Africa, including detailed models for Addis Ababa, as part of a project together with AfricaArray, funded by USAID (see also http://www.globalquakemodel.org/what/working-together/worldwide-projects/)

Best practice & risk assessment approaches

​

  • Ground Motion Prediction Equations â€“ series of technical reports that facilitate GMPE selection in various contexts; download the main report here, other reports can be found on GEM Nexus

 

  • 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; use the main technical report, the report on the glossary or go to the GEM Nexus page for online use of the taxonomy and glossary. See also above information on the TaxT tool.

 

  • Risk and Resilience Scorecard â€“ an innovative approach for community-based measurement of resilience, which has been tested in Nepal. Supporting documentation on the methodology is under development.

 

Risk Information

Within the OpenQuake Platform, users can explore maps, curves, tables and other types of risk information calculated with models. Users can also down- load them in different formats for further use.

​

Maps and layers

​

  • All datasets and results of single calculations are represented as layers (https://platform.openquake.org/layers/) in the platform. A layer can be downloaded in a great variety of formats for further use.

 

 

  • All layers come with metadata, which include the person / organization who developed the layer and could also include the license.

 

  • All layers and maps can be rated and commented upon by the community.
