OpenQuake (OQ) - comprised of the engine, platform and tools - caters to a variety of users, from modellers and researchers to emergency planners - OpenQuake is used for a wide range of purposes for disaster risk reduction and management.
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.
For modellers, researchers, scientists and engineers
OQ Engine Key Features

Explicit representation of uncertainty, including separation of epistemic from aleatory
Runs risk calculations for precomputed hazard curves and ground motion fields
OQ Engine Calculators and Outputs
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 browsing and downloading data, follow the instructions below.
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.
To customize or create your own maps, click Maps > Create Maps
Click the Add Layer icon and select from the available layers from the dropdown list.
Save and Publish your map.
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.

Guidelines for component-based analytical vulnerability assessment of buildings and nonstructural elements
A procedure is offered for the analytical derivation of the seismic vulnerability of building classes, that is, probabilistic relationships between shaking and repair cost as a fraction of replacement cost new for a category of buildings.
