The off-shore maximum surface elevation is multiplied by the factor to achieve the MIH estimation. This service is part of the candidate Thematic Core Service for tsunami and will be integrated into the Integrated Core Service Data Portal of the European Plate Observing System (EPOS).

The primary objective of this service will be to give scientists a tool for regional tsunami hazard evaluations, based on time series extracted by tsunami propagation models, without running computational costly run-up models along the coastlines.  Example on global evaluation of MIH is found in Figure 2.

The model provides / will provide the following features:

  • Interface for extraction of the wave characteristics from off-shore mariograms (time history of the surface elevation at a gauge)
  • Extract the amplification factors based on the wave characteristics
  • Calculation of the maximum inundation height
  • Creating hazard maps

The method is described in the following open access publications:
