Volcanic hazard impacts to critical infrastructure: A review

摘要: Abstract Effective natural hazard risk assessment requires the characterisation of both hazards and vulnerabilities exposed elements. Volcanic is at an advanced state a considerable focus volcanic scientific inquiry, whereas comprehensive vulnerability lacking. Cataloguing analysing impacts provide insight on likely societal physical during future eruptions. This paper reviews documented disruption damage critical infrastructure elements resulting from four (tephra fall, pyroclastic density currents, lava flows lahars) eruptions in last 100 years. We define as including energy sector infrastructure, water supply wastewater networks, transportation routes, communications, components. Common trends are summarised, which can be used to assess reduce for In general, tephra falls cause these sectors, reducing their functionality, whilst flow (pyroclastic more destructive causing permanent damage. should include quantification we challenge volcanology community address this through implementation standardised methodology development use fragility functions, has been successfully implemented other fields.
