Get started: OQ Engine

The OpenQuake Engine is the Global Earthquake Model Foundation’s (GEM) state-of-the-art, open-source software collaboratively developed for earthquake hazard and risk modelling. It runs on operating systems such as Linux, macOS and Windows; and can be deployed on laptops, desktops, standalone servers and multi-node clusters. The functionality to analyze hazard and risks at specific site, city, country or regional level makes the OpenQuake Engine a powerful and dynamic tool for assessing the potential impacts of earthquakes at any location in the world.

  • stochastic earthquake event sets and ground motion fields, hazard curves, hazard maps

 

Scenario hazard:

  • single event - stochastically generated ground motion fields

Additional features:

  • 5 typologies for modeling seismic sources

  • 100+ GMPEs implemented and tested

  • Tools for harmonizing catalogs, creating seismogenic input files, analyzing strong motions and GMPEs

PHYSICAL RISK

Classical PSHA-based:

  • asset-specific loss exceedance curves, average annual loss, loss maps, building typology disaggregation

Compatibility

Compatible with various existing hazard, vulnerability and exposure models

Calculations

OQ Engine Calculators and Outputs

OQ Platform

The OpenQuake Platform is a website that allows the community to explore, manipulate and visualize the datasets and models and to use tools that GEM produces. The platform also allows users to contribute, share and discuss new findings and results with the GEM community.

Share your outputs - datasets, maps, models - to the GEM OpenQuake community through the Platform. The OpenQuake Platform hosts a number of national, regional and global models. Follow the instructions below to access data from GEM and the OQ community. For users who only need outputs such as datasets, layers or maps, you can simply register for free and browse the Platform for the data that you need.

To start sharing your data, follow the instructions below.

  1. Sign in or register here.

  2. Click Layers > Upload Layers

  3. Create maps based on GEM’s existing datasets or create one based on your uploaded Layer. Click Maps > Create Maps

  4. Save and Publish your map to share with the OpenQuake community.

To start browsing and downloading data, follow the instructions below.

  1. Sign in or register here.

  2. In the Search box, type the name of the map or dataset you’re looking for. Look for your item from the search results, click to Download.

  3. To customize or create your own maps, click Maps > Create Maps

  4. Click the Add Layer icon and select from the available layers from the dropdown list.

  5. Save and Publish your map.

  6. Download your map.

Openquake: Tools and Data

GEM works on a wide range of open-source source (software) tools to allow you to calculate, share and explore earthquake risk. Most of these are already embedded in the platform, but others are released as stand-alone applications.

Openquake: Training

The OpenQuake online training is designed for an audience with a diverse background and expertise and covers the main concepts of earthquake risk assessment, along with the basic features of the engine.

 

The training activities have been tailored for beginner users, and are divided into four modules that cover different types of calculations using the OpenQuake-engine.

 

​Each module is approached from a technical and practical perspective. It includes a theoretical introduction, followed by step-by-step examples that help to consolidate the concepts, as well as exploring the OpenQuake tools for each type of calculation.

Learn the basics to perform volcanic risk scenarios using the OpenQuake engine. In this video we cover the main components of a seismic risk model and discuss how their modelling assumptions and products may be useful for volcanic risk assessment. We include a hands-on exercise using the software to calculate volcanic risk and the QGIS OpenQuake plug-in to export and visualize results, like total losses and loss maps for the El Ruiz Volcano.
