The NEAM Tsunami Hazard Model 2018 (NEAMTHM18; https://doi.org/10.13127/tsunami/neamthm18) is a time-independent probabilistic hazard model for tsunamis generated by crustal and subduction-zone earthquakes. The dataset covers the coastlines of the North-Eastern Atlantic, the Mediterranean, and connected Seas (NEAM).
The metric used for the tsunami intensity is the Maximum Inundation Height (MIH, in meters), calculated by applying local amplification factors (AF) to the offshore maximum tsunami amplitudes obtained at 2,336 Points of Interest (POI) distributed in the North-Eastern Atlantic (1,092 POIs), the Mediterranean Sea (1,107 POIs), and the Black Sea (137 POIs) at an average spacing of ~20 km and an average depth of ~50 m.
We provide the mean hazard curve together with five different percentiles to illustrate the model epistemic uncertainty, namely: the 2nd, 16th, 50th, 84th, and 98th percentiles.
NEAMTHM18 data is offered through web services adopting the OGC standards (WFS and WMS). This service is part of the candidate Thematic Core Service for tsunami and is integrated into the Integrated Core Service Data Portal of the European Plate Observing System (EPOS).
