Abstract

This map presents the admin level 0 (i.e. country-based) results of the beta (i.e. test) version of the 2020 European Seismic Risk Model (ESRM20), which are being made available as part of the community preview. The following risk metrics are provided as separate layers: Average Annual Loss (AAL), Average Annual Loss Ratio (AALR), 200-years return period loss. By clicking on a given country on the map, you can also access (in the sidebar) the breakdown of these losses per occupancy class (residential, commercial and industrial) as well as the data of the exceedance probability curve (represented as loss versus return period).

The following additional layers can be added to the maps: social indicators and events from the NCEI/WDS Global Significant Earthquake Database. Once the social indicator layer is enabled, clickng on a given country will present the social indicator data and associated year and source. The NCEI/WDS Global Significant Earthquake Database (NGDC/WDS) has been filtered to consider events in European countries from 1920 to 2020. Clicking on a specific event will present a summary of the main characteristics of the earthquake and associated damage and loss.

Definitions

The Average Annual Loss (AAL) represents the long-term mean loss value per year due to direct damage caused by earthquake ground shaking in the residential, commercial and industrial building stock, considering structural and non-structural components and building contents.

The Average Annual Loss Ratio (AALR) for the country represents the average annual loss normalized by the total asset replacement cost within the country.

The 200-years return period loss represents the long-term mean loss value due to direct damage caused by earthquake ground shaking in the residential, commercial and industrial building stock, considering structural and non-structural components and building contents, that is expected to be equalled or exceeded at least once every 200 years.
