Case Studies Highlighting Impacts of Ashfall

Past impacts and mitigation strategies for specific eruptions are catalogued here. Case studies are detailed further for impacts on grouped sectors, which appear under their relevant topic headings.

The eruption is briefly described in an overview discussing the size and volume of ash dispersed where figures are known or approximated. There are four categories discussed where impacts are documented:

• Health – direct and indirect from exposure
• Infrastructure – includes (where applicable) building, transportation, power network, communication, water and wastewater treatment.
• Agriculture and Primary Industries – includes livestock, pastoral land, horticulture and forestry.
• Emergency management – monitoring, response during the eruption and recovery post eruption.

Please contact the Ash Web Team if you would like to contribute additional case study information. We are always looking for additional information.
