The development of probabilistic seismic risk assessment (PSRA) models requires stress-testingthe various components of the models, often through the assessment of damage and lossesconsidering the characteristics of past events¹. In this context, the GEM Foundation andits partners have expanded the OpenQuake scenario damage and loss calculator to use directlyUSGS ShakeMaps²³⁴, or earthquake data from other providers (e.g., INGV, EFEHR) or thescientific literature. This functionality allows users to generate cross-correlated groundmotion fields considering recordings from seismic stations⁵, to compute a number ofrisk metrics based on different rupture solutions and ground motion models, and to compare theresults against past observations and damage reports. An overview of the functionalities implementedwithin the OpenQuake engine can be found atgem/oq-engine#8317.

The Global Earthquake Impact Database (GEID) aims to provide both earthquake and impact datafor users to perform earthquake scenarios using GEM or their own models for validationand verification purposes. This database serves as a complement to theUSGS ShakeMap Atlas and AtlasCat.The former resource has ShakeMaps for a comprehensive catalogue of nearly allnear-damaging and damaging events worldwide for the past 120 years and can be used directlyfor impact assessment within the OpenQuake engine⁴. The latter provides aggregate lossesfor each event separated by cause. The GEID builds upon these sources of data by collecting additionalearthquake 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(seecontributing guidelines) or to provide additional data toexisting entries. We aim to continue expanding the GEID by leveraging on data often collected withinthe scope of GEM projects, as well as data previously collected as part of theGEM Earthquake Consequences Database.

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.

The following events are available, with a global summary of impact data available in theWorld folder.
