| Zusammenfassung |
The uncertainty brought about by intermittent volcanic activity is fairly
common at volcanoes worldwide. While better knowledge of any one volcano's
behavioural characteristics has the potential to reduce this uncertainty,
the subsequent reduction of risk from volcanic threats is only realised if
that knowledge is pertinent to stakeholders and effectively communicated to
inform good decision making. Success requires integration of methods, skills
and expertise across disciplinary boundaries.
This research project develops and trials a novel interdisciplinary approach
to volcanic risk reduction on the remote volcanic island of Tristan da Cunha
(South Atlantic). For the first time, volcanological techniques,
probabilistic decision support and social scientific methods were integrated
in a single study. New data were produced that (1) established no
spatio-temporal pattern to recent volcanic activity; (2) quantified the high
degree of scientific uncertainty around future eruptive scenarios;
(3) analysed the physical vulnerability of the community as a consequence of
their geographical isolation and exposure to volcanic hazards; (4) evaluated
social and cultural influences on vulnerability and resilience; and
(5) evaluated the effectiveness of a scenario planning approach, both as a
method for integrating the different strands of the research and as a way of
enabling on-island decision makers to take ownership of risk identification
and management, and capacity building within their community.
The paper provides empirical evidence of the value of an innovative
interdisciplinary framework for reducing volcanic risk. It also provides
evidence for the strength that comes from integrating social and physical
sciences with the development of effective, tailored engagement and
communication strategies in volcanic risk reduction. |
