🔎 Global Earthquake Impact Database (GEID)

The development of probabilistic seismic risk assessment (PSRA) models requires stress-testing the various components of the models, often through the assessment of damage and losses considering the characteristics of past events[^1]. In this context, the GEM Foundation and its partners have expanded the OpenQuake scenario damage and loss calculator to use directly USGS ShakeMaps[^2][^3][^4], or earthquake data from other providers (e.g., INGV, EFEHR) or the scientific literature. This functionality allows users to generate cross-correlated ground motion fields considering recordings from seismic stations [^5], to compute a number of risk metrics based on different rupture solutions and ground motion models, and to compare the results against past observations and damage reports. An overview of the functionalities implemented within the OpenQuake engine can be found at https://github.com/gem/oq-engine/issues/8317.

✨ Overview

The Global Earthquake Impact Database (GEID) aims to provide both earthquake and impact data for users to perform earthquake scenarios using GEM or their own models for validation and verification purposes. This database serves as a complement to the USGS ShakeMap Atlas and AtlasCat. The former resource has ShakeMaps for a comprehensive catalogue of nearly all near-damaging and damaging events worldwide for the past 120 years and can be used directly for impact assessment within the OpenQuake engine [^4]. The latter provides aggregate losses for each event separated by cause. The GEID builds upon these sources of data by collecting additional earthquake and impact information, often documented spatially and with greater detail.

The v2023.0.0 release for the Global Earthquake Impact Database (GEID) is available! 🥳 🚀

This database is open and aims at being a community effort, that enables users to add new events (see contributing guidelines) or to provide additional data to existing entries. We aim to continue expanding the GEID by leveraging on data often collected within the scope of GEM projects, as well as data previously collected as part of the GEM Earthquake Consequences Database.

🗺️ Database coverage

The database is compatible with GEM's Global Models, and the folders are organized according to regions and countries/territories, as specified in the map and table below.
