| Zusammenfassung |
| This paper presents an integrated approach to conduct a scenario-based
volcanic risk assessment on a variety of exposed assets, such as residential
buildings, cultivated areas, network infrastructures or individual strategic
buildings. The focus is put on the simulation of scenarios, based on
deterministic adverse event input, which are applied to the case study of an
effusive eruption on the Mount Cameroon volcano, resulting in the damage
estimation of the assets located in the area. The work is based on the recent
advances in the field of seismic risk. A software for systemic risk scenario
analysis developed within the FP7 project SYNER-G has been adapted to address
the issue of volcanic risk. Most significant improvements include the
addition of vulnerability models adapted to each kind of exposed element and
the possibility to quantify the successive potential damages inflicted by a
sequence of adverse events (e.g. lava flows, tephra fall, etc.). The use of
an object-oriented architecture gives the opportunity to model and compute
the physical damage of very disparate types of infrastructures under the same
framework. Finally, while the risk scenario approach is limited to the
assessment of the physical impact of adverse events, a specific focus on
strategic infrastructures and a dialogue with stakeholders helps in
evaluating the potential wider indirect consequences of an eruption. |
