- Risk Information

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.

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.

​

• Hazard Modeller’s Toolkit (hmtk): An extensive suite of tools for pre-processing information (e.g. earthquake catalogues) and for the creation of the hazard source model is now available through the OpenQuake engine.

​

• 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.

​

• Physical Vulnerability Data Suite: tool to explore and contribute physical vulnerability functions;  integrated into the OpenQuake Platform

Knowledge Sharing & Data Facilitating Apps

TaxTweb: Tool to facilitate use of the GEM Building Taxonomy

​

• Available on the OpenQuake Platform (https://platform.openquake.org/taxtweb/)

​
 

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. 

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.
 

• ISC-GEM Global Instrumental Earthquake Catalogue: a global instrumental seismicity catalogue compiled using uniform criteria and containing about 20,000 earthquakes that occurred between 1900 and 2009 – explore in the platform 
   

• Global Historical Earthquake Catalogue and Archive: an archive covering 994 earthquakes that occurred between 1000 and 1903 and a homogenous catalogue of 885 events of magnitude >= 7 extracted from that archive – explore in the platform
   

• Global Geodetic Strain Rate Model: a numerical model obtained from 22,400+ GPS velocities measuring plate motion – explore in the platform 
   

• Homogenous Active Faults Database: global database of active faults, folds and fault sources that integrates currently available national and regional databases worldwide – explore in the platform
   

• Global Exposure Database: a multi-scale database of global buildings and population distribution worldwide. There are two ways to explore exposure data in the platform: 1. download small subsets at https://platform.openquake.org/exposure/ for a region of your interest, and 2. browse the HAZUS building fractions for the US at https://platform.openquake.org/hazus/
   

• Global Earthquake Consequences Database: captures a full spectrum of earthquake consequences; both for humans and structures; it currently features complete data on 66 significant earthquakes (mainly 1970-2011) – explore in the platform
   

• GEM Physical Vulnerability Functions Database: existing and newly derived sets of empirical, analytical and expert opinion fragility and vulnerability functions from around the world – explore in the platform; see also under Software / Tools
   

• Social Vulnerability Indices: includes 197 countries worldwide, consisting of data from 44 publicly available sources – explore in the platform 

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.

​

• Learn about and download the hazard models that we currently share with the community, through this wiki (https://hazardwiki.openquake.org/start).

• 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/)

​

• Ground Motion Prediction Equations – 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 – an innovative approach for community-based measurement of resilience, which has been tested in Nepal. Supporting documentation on the methodology is under development.

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.

• Create custom maps (https://platform.openquake.org/maps/) by combining several layers, or import own data layers. GEM encourages users to share with the community.

• 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.
