S3.13: Volcanic ashfall, gas and acid rain impacts: current and future research and resources in support of preparedness, assessment and mitigation
Special accommodations: This session has been developed in collaboration with and is intended to pair with the Ashfall/Gas/Acid Rain Workshop proposed by Carol Stewart et al.
Understanding volcanic impacts and how to reduce or manage their effects forms a cornerstone of volcanic disaster risk reduction. Multi-volcanic hazards occurring simultaneously and/or sequentially can be challenging to assess and manage the likely impacts. Volcanic ash, gas and acid rain are hazards which often occur together and collectively have the largest footprint of all volcanic phenomena: they are most likely to affect the greatest number of people. It maybe difficult to attribute specific impacts to just one of these three phenomena; recent experience highlights the need to consider these collectively.This session aims to explore how science can improve management of volcanic impacts through field and laboratory-based assessment of impacts and mitigation measures, and the translation and application of this knowledge into volcanic risk management approaches. This includes exploring how to assess impacts from long-duration, multiple and cascading hazards across complex systems as well as the longer term effects of disruption. We invite volcano scientists, city and emergency managers, environmental monitoring agencies and health professionals to work together to:
- Share current knowledge and new research concerning impacts and mitigation resources for ash, gas and acid rain
- Share case studies of recent eruptions where civil authorities grappled with the combined impact of ash, gas, and acid rain, exploring key lessons and implications for best practice
This session is sponsored by the IAVCEI Cities and Volcanoes Commission, International Volcanic Health Hazard Network, and the Volcanic Ashfall Impacts Working Group, and will pair with the post-conference Ash/Gas/Acid Rain workshop.Core connection with societal risk mitigation: Volcanic ash, gas and acid rain often occur together and collectively have the largest footprint of all volcanic phenomena: they are the most likely to affect the greatest number of people. Effective mitigation of ash, gas and acid rain impacts is a cornerstone of volcanic disaster risk reduction.
