WP4 Multi-hazard ex-emplification: seismic and landslide risk

Lead: NGI

Based on the multi-resolution dynamic vulnerability framework developed in WP3, WP4 deals with the application of the framework for seismic and landslide risk in three test cases. In the Cologne test case additional hazard could be considered, as e.g. floods. Since risk and vulnerability vary for different types of natural hazards and for different geographical regions, the scope of a monitoring framework has to be adapted to local and hazard-specific conditions. In this context, the spatia-temporal variability of risk and vulnerability has to be taken into account. The dynamic development of local risks can be assessed by detecting changes in hazard indicators like rainfall and vegetation coverage (for landslide and flood hazard) or vulnerability indicators changing over time and space, such as urban growth, changes in settlement structures, environmental changes or migration, Thus, to continuously monitor risk and vulnerability, hazard indicators and hazard specific vulnerability indicators have to be determined and specified. These indicators, covering a range of spatial scales, can be obtained by either remote sensing techniques or in-situ measurements. To adopt an indicator set and a monitoring framework to local conditions, end-users needs with respect to the desired time frame and geographical scale (or level of detail) of analysis need to be assessed and already existing data and information collected. The results of such an initial monitoring planning phase can then be inferred into the monitoring framework and therefore optimise the model accordingly.

The main goal of WP4 is therefore to extract vulnerability indicators for landslide and earthquake risk and to develop a prototype vulnerability monitoring framework for three test cases.

The key objectives of WP 4 are:

  • Identify the end user needs in terms of information and data required to direct and support earthquake and landslide preparedness.
  • Review and determination of indicators relevant for monitoring spatia-temporal changes in vulnerability to earthquakes and landslides.

Development of a prototype vulnerability monitoring framework for earthquakes and landslides for selected test-cases/end-users (including the application of the concept of focus maps).
