Integrated Risk

Exposure Database

A large global and open database that contains information on the population and on and the number / built area / replacement cost of buildings for a urban and rural areas, both for residential and non-residential buildings. The database features 4 different levels: national, sub-national, community and building-to-building. The database’ first version (2014) will comprise aggregated data on national and sub-national level. Information at the community level and building-by-building will be available only for selected areas.

Building Taxonomy

The GEM Building Taxonomy is a uniform classification scheme of buildings across the globe. It is used as a basis for assessing the risk from earthquakes within the scope of GEM. The taxonomy self, but mainly the glossary of 400 definitions and 600 images facilitates global collaboration and growing of our joint knowledge on the diversity and seismic vulnerability of all the buildings that exist around the globe.

Earthquake Consequences Database

A database of the different consequences of past earthquakes, in terms of damage, casualties (people that were injured), socio-economic consequences and recovery data, due to ground shaking, landslides, liquefaction, tsunamis and fire following an earthquake. The dataset is based on 65+ important earthquakes (1923-2011), including Tohoku and Haiti.

Inventory Data Capture Tools

A set of open-source tools to capture data on exposure and on earthquake consequences. OpenQuake users will be able to upload information on single buildings that they captured by using mobile apps or paper forms that are based on the GEM Building Taxonomy. Other tools allow users to identify building footprints and add attribute information from remote sensing imagery. They can do so for developing exposure datasets or to capture information on consequences in the aftermath of an earthquake. After validation this data can be integrated into the Global Exposure Database or the Global Consequences Database.

Physical Vulnerability

A dataset of existing and newly derived sets of empirical, analytical and expert opinion fragility and vulnerability functions from around the world that have been quality rated. These functions form the basis for damage estimation and for loss estimation in terms of fatalities (people that lost their lives) and building repair costs.

Socio-Economic Vulnerability and Resilience Data and Tools

Data and tools that allow for the integrated evaluation of earthquake risk worldwide, by combining physical risk with the socio-economic vulnerability and resilience of communities.  Transparent indices for all countries will help to understand the impact of the socio-economic environment in earthquake disaster. In addition, several tools and a large database will allow OpenQuake users to develop their own indices and thereby their own assessments, incorporating their local knowledge.
