The European Tsunami Risk Service (ETRiS) is a DDSS (Data, Data Products, Services, and Software) service for tsunami risk. This service is part of the Thematic Core Service tsunami (TCS Tsunami) and is integrated into the Integrated Core Service Data Portal of the European Plate Observing System (EPOS-ICS-C).
The primary objective of this service is virtual access provision for DDSS for tsunami vulnerability and risk components.
This web platform will provide some essential DDSS required for probabilistic tsunami risk analysis (PTRA) such as:
- Datasets (selected raw/processed datasets of impact and damage incurred by tsunamis)
- Data Products (damage scales, fragility curves, consequence models, vulnerability curves)
- Maps (visualizing data products and data sets)
- The Tsunami Risk Modeller’s Toolkit (software and tools for tsunami risk analysis, stand-alone software and tools for post-processing raw data, model testing and validation)
- Training activities and material (presentations, recordings, and related material of ETRiS online training activities)
A full description of the PTRA workflow and terminology can be found in Behrens et al., (2021).
Figure 1 below shows a schematic overview of the main variables in PTRA.
- IM: Tsunami intensity measure (e.g., wave amplitude, flow depth, current velocity, momentum flux, or maximum inundation height)
- DM: Damage measure (e.g., a physical damage state)
- DV: decision variable (e.g., fatalities, repair costs, downtime)
