Dataset
Active Faults Database
License type:
CC BY-SA 4.0
The GEM Foundation's Global Active Faults is building a comprehensive, global dataset of active fault traces of seismogenic concern. This repository comprises GIS files of fault traces and small amount of relevant attributes or metadata (fault geometry, kinematics, slip rate, etc.) useful for seismic hazard modeling and other tectonic applications. The dataset is being assembled primarily as a part of GEM's global Probabilistic Seismic Hazard Modeling efforts, although we hope that the data find wide use in research, education and general interest among many users.
The dataset currently covers most of the deforming continental regions on earth with the exceptions of the Malay Archipelago, Madagascar, Canada, and a few other regions.
Model
Africa Exposure
License type:
CC BY-SA 4.0/CC BY-NC-SA 4.0
The Global Exposure Model is a mosaic of local and regional models with information regarding the residential, commercial, and industrial building stock at the smallest available administrative division of each country and includes details about the number of buildings, number of occupants, vulnerability characteristics, average built-up area, and average replacement cost.
The dataset is developed and maintained by the GEM Foundation, using a bottom-up approach at the global scale, using national statistics, socio-economic data, and local datasets. This model allows the identification of the most common types of construction worldwide, regions with large fractions of informal construction, and areas prone to natural disasters with a high concentration of population and building stock.
The Africa region of the model includes the information pertaining the following countries/territories:
Algeria, Angola, Benin, Botswana, Burkina_Faso, Burundi, Cameroon, Cape_Verde, Central_African_Republic, Chad, Comoros, Congo, Democratic_Republic_of_the_Congo, Djibouti, Egypt, Equatorial_Guinea, Eritrea, Eswatini, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea_Bissau, Ivory_Coast, Kenya, Lesotho, Liberia, Libya, Madagascar, Malawi, Mali, Mauritania, Mauritius, Morocco, Mozambique, Namibia, Niger, Nigeria, Rwanda, Sao_Tome_and_Principe, Senegal, Seychelles, Sierra_Leone, Somalia, South_Africa, South_Sudan, Sudan, Tanzania, Togo, Tunisia, Uganda, Zambia, Zimbabwe

Alaska Hazard
License type:
CC BY-SA 4.0
The 2007.0.0 seismic hazard model for Alaska (USA) was developed by the United States Geological Survey (Wesson et al., 2007). The model covers the state of Alaska including the Aleutian Islands. The model has been translated from its original format into the OpenQuake (OQ) engine by GEM.
Since the original version, an update was made to the model by the GEM hazard team, leading to the latest release (v2007.1.0), which was used in the computation of the 2023 Global Earthquake Hazard and Risk Maps. This model incorporates the GMPEs recommended by Mueller et al. (2015) for Alaska.
Model
Arabia Hazard
License type:
CC BY-SA 4.0
The 2018.0.0 seismic hazard model of the Arabian Peninsula (ARB) was developed by the Saudi Geological Survey (SGS). The model covers Saudi Arabia, Yemen, Oman, and Qatar, but does not include sources that originate in the Zagros region of western Iran. The model has been translated into the OpenQuake (OQ) engine format by GEM.
Since the original version, several significant updates have been made to the model by the GEM hazard team, leading to the latest release (v2018.2.0), which was used in the computation of the 2023 Global Earthquake Hazard and Risk Maps. Differences in the versions can be consulted in the model documentation.

Caribbean & Central America Hazard
License type:
CC BY-SA 4.0
The original model covering the Central America and the Caribbean region (v2018.0.0) was initially developed in the framework of the CCARA project, a GEM collaboration project funded by USAID. Cuba and Puerto Rico were included a posteriori by the GEM hazard team. During the CCARA project and after it, some local organizations and experts were involved and this models benefits of it: University of Costa Rica, Costa Rica - Costa Rican Institute of Electricity, Costa Rica - Nicaraguan Institute of Territorial Studies, Nicaragua - Catholic University of El Salvador, El Salvador - Ministry of Environment and Natural Resources, El Salvador - Panama University, Panama, Puerto Rico Seismic Network, Puerto Rico, National Center for Seismological Research, Cuba. The model was built as a combination of a shallow model, where active faults and distributed seismicity sources were integrated, and a subduction model, divided into its main components (i.e. interface and in-slab). The interface seismicity was modelled using complex faults, while for the in-slab region, the typology of source preferred was the non-parametric source.
Since the original version, several significant updates have been made to the model by the GEM hazard team, leading to the latest release (v2019.1.0), which was used in the computation of the 2023 Global Earthquake Hazard and Risk Maps. Differences in the versions can be consulted in the model documentation.
