Pillar 4 - Hazard and Risk Products

European Tsunami Risk Service

ETRiS provides researchers with data and tools (e.g., tsunami consequence data, vulnerability models, software for data post-processing and visualization) useful for probabilistic tsunami risk assessment (PTRA). ETRiS aims at provision of DDSS with specific attention to multi-hazard exposure and vulnerability and multi-risk research questions.

This dataset consists of the tsunami part of the Global Risk model, and consists of a combination of probabilistic tsunami hazard assessment (PTHA), and GIS analysis for providing tsunami inundation maps. The data are provided for a return period of 500 years. The maps are projected on open source topographic data. The PTHA analysis contains a range of different steps, including simulations of thousands of scenarios, and is documented in the following references Tsunami exposure is calculated by combining a global population dataset (GRUMP) with STRM terrain model and projected tsunami inundation heights using global amplification factors.

Probabilistic Tsunami Hazard Model for the NEAM Region

The NEAM Tsunami Hazard Model 2018 (NEAMTHM18) is a time-independent probabilistic hazard model for tsunamis generated by earthquakes. The online data covers the coastlines of the North-East Atlantic, the Mediterranean, and connected Seas (NEAM).

The TMV provides the inundation maps related to potential tsunami events potentially affecting the Italian coasts. The inundations are calculated based on the NEAM Tsunami Hazard Model 2018 - NEAMTHM18 (Basili et al., 2018; 2021), referring to the 84th percentile hazards curves and an average return period of 2500 years. The processing methodology is based on the application through GIS tools of an empirical attenuation rule between the design run-up values and the maximum expected onland ingression (detailed description in Tonini et al., 2021). The inundation maps refer to two distinct alert levels (advisory and watch), for which two distinct services are provided: Inundation Map, Advisory zone; Inundation Map, Watch zone The web viewer and the services are hosted by ISPRA - Istituto Superiore per la Protezione e la Ricerca Ambientale Link to the homepage of the service
