🔎 GEM Earthquake Scenario Database

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 events¹. In this context, the GEM Foundation and its partners have expanded the OpenQuake scenario damage and loss calculator to use directly USGS ShakeMaps²³⁴, 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, and 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 in gem/oq-engine#8317.

✨ Overview

The Earthquake Scenario Database (ESD) aims at providing 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 ESD 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 GEM's Earthquake Scenario Database 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 ESD 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.
